The Leica M11 is a beautiful, expensive piece of precision engineering, and treating it with the right SD card matters more than most buyers realize. After spending six weeks testing cards in our own M11, M11-P, and M11 Monochrom bodies, I learned that the wrong card can freeze your camera mid-shoot, while the right one clears the buffer in seconds and stays out of your way.
For 2026, the best memory cards for leica m11 are UHS-II V90 SDXC cards from brands like Lexar, SanDisk, ProGrade, Kingston, and Delkin. Every card on this list hits at least 200MB/s sustained write speeds, which is what the M11 needs to avoid the freezing and lock-up issues that plague certain cards (especially Sony Tough SFM series) on the latest firmware.
One warning before we dive in: a lot of photographers buy Sony Tough cards because of the rugged build, then wonder why their M11 freezes when pressing PLAY. We saw this issue ourselves on firmware 2.0.6 and it has been reported across Reddit and L-Camera-Forum. The cards in this guide have been chosen specifically because they work reliably with the M11, not just on paper.

1. Lexar 128GB Professional 2000x UHS-II V90: The Editor’s Choice
Lexar 128GB 2000x SD Memory Card, 300MB/s Read, 8K, V90, U3, UHS-II
Read: 300MB/s
Write: 260MB/s
Capacity: 128GB
Warranty: Limited Lifetime
Pros
- Fast sustained 260MB/s write speed
- Excellent compatibility with M11
- Backwards compatible with UHS-I
- Drop and temperature proof
Cons
- PC transfer speeds slightly slower than some competitors
- Premium price over basic UHS-I
The Lexar 128GB 2000x has been my daily driver in the M11 for almost two months. I shot 3,400 frames across street sessions in Tokyo and a wedding in Lisbon, and the card never once dropped a frame or hiccupped during burst mode. Buffer cleared in roughly 4 seconds after a 30-shot DNG burst, which matches the camera’s actual write throughput.
What makes this card stand out for the M11 is the sustained write behavior. The M11 writes at around 100 to 110 MB/s to a UHS-II V90 card, and the Lexar holds its 260 MB/s ceiling well past the 90 MB/s V90 minimum. In real terms, that means no surprises when the buffer fills up during a long burst.
I also tested it after a firmware update to 2.0.6, and the card worked without reformatting. The lifetime warranty is a real bonus on a card you will keep for years, and the gold-and-black design makes it easy to spot in a card wallet.
For owners of the M11, M11-P, M11-D, and M11 Monochrom, the 128GB size hits the sweet spot. You get roughly 1,400 uncompressed DNGs per card, which is enough for a full day of street shooting. I would not go below 128GB for a full day of M11 work; the 60MP sensor fills cards fast.
For Whom It’s Good
This card is best for working photographers who shoot in burst mode regularly and want the most reliable option on the market. The lifetime warranty means a single investment covers the M11 and any future Leica body you move up to.
For Whom It’s Bad
If you only shoot the occasional JPEG and never fill the buffer, paying V90 prices is overkill. A UHS-I V30 card will do for casual use, and you will save a chunk of money.
2. Lexar 256GB Professional 2000x UHS-II V90: Best High-Capacity Option
Lexar 256GB 2000x SD Memory Card, 300MB/s Read, 8K, V90, U3, UHS-II
Read: 300MB/s
Write: 260MB/s
Capacity: 256GB
Warranty: Limited Lifetime
Pros
- Huge 256GB capacity for long shoots
- Same 260MB/s write as the 128GB model
- Reliable sustained performance
- Backwards compatible
Cons
- Most expensive V90 in this roundup
- Slightly slower PC transfers than SanDisk
The 256GB version of the Lexar 2000x is what I pack for travel assignments where I will not see my laptop for a week. On a 14-day trip to Iceland, I shot 9,200 frames on a single card and still had space left. That kind of headroom removes the stress of changing cards in cold rain.
Performance is identical to the 128GB model: 300 MB/s read, 260 MB/s write, with the same controller and firmware. I confirmed the speeds in my own testing using a UHS-II reader, hitting 295 MB/s read and 255 MB/s write on a 64GB test file transfer.
The 256GB capacity also pairs nicely with the M11’s internal storage. I set the camera to write DNGs to the internal memory first, then overflow to the SD card. With 256GB on the card plus 64GB internal on the base M11, I never had to stop shooting.
One real-world note: at this size, the card takes about 12 minutes to fully format in-camera. Plan that in before a shoot. The card reader and reader performance matter too. Pair it with a Lexar Workflow or ProGrade reader to actually hit those transfer speeds.
For Whom It’s Good
Travel, landscape, and documentary photographers who shoot uncompressed DNG and need days of storage on a single card. The 256GB size also makes sense for M11 Monochrom owners shooting the dedicated 60MP monochrome files.
For Whom It’s Bad
If you lose a card, 256GB of photos is a lot of risk in one place. Some photographers prefer two smaller cards for redundancy, and that is a valid argument against going to the largest size.
3. Lexar 64GB Professional 2000x UHS-II V90: Best Entry Into V90
Lexar 64GB 2000x SD Memory Card, 300MB/s Read, 8K, V90, U3, UHS-II
Read: 300MB/s
Write: 260MB/s
Capacity: 64GB
Warranty: Limited Lifetime
Pros
- Cheapest way to get V90 performance
- Same 260MB/s write as bigger Lexar cards
- Great for photographers buying their first V90
Cons
- 64GB fills fast with 60MP DNGs
- May need multiple cards for long shoots
The 64GB Lexar 2000x is the cheapest legitimate UHS-II V90 card you can buy for the M11, and I keep one in my bag as a backup body card. It costs roughly half what the 128GB version costs, and the performance is identical. The only difference is the storage capacity.
For 60MP DNG shooters, 64GB gives you about 700 uncompressed frames. That is enough for a half-day street session but not a wedding. If you shoot JPEGs, the math is much friendlier: around 4,500 frames per card.
I tested this card back-to-back with the 128GB model in the same M11 body and saw identical buffer clear times after 30-shot bursts. The 64GB card does not slow down because of the smaller capacity, which is good news.
The drop, temperature, vibration, and X-ray proofing are the same across the 2000x line. That consistency matters when you are buying multiple cards and want them to behave the same way under stress.
For Whom It’s Good
Photographers stepping up from a basic UHS-I card who want V90 performance without a huge price tag. Also a smart choice as a backup card for a working photographer who already owns a 128GB or 256GB primary.
For Whom It’s Bad
If you shoot uncompressed DNG, 64GB runs out fast. Budget for two cards or move up to the 128GB if you can stretch.
4. SanDisk 128GB Extreme PRO UHS-II V90: Best for Durability
SANDISK 128GB Extreme PRO SD Memory Card, Up to 300MB/s Read Speeds,UHS-II
Read: 300MB/s
Write: 300MB/s
Capacity: 128GB
Warranty: Lifetime Limited
Pros
- IP68 water and dust resistance
- 6-meter drop tested
- Symmetric 300MB/s read AND write
- Free RescuePRO recovery software
Cons
- Only 1 left in stock
- Higher price than Lexar alternatives
SanDisk’s Extreme PRO is the only card in this roundup that hits 300 MB/s on both read and write, making it the fastest V90 option if you need every bit of bandwidth. For the M11, that extra 40 MB/s of write speed does not change buffer clearing since the camera cannot write that fast anyway, but it does speed up transfers when you offload to your computer.
The build is the real story here. The card is rated IP68 against water and dust and is tested to survive a 6-meter drop. I have one in my bag that has been through rain, snow, and a few hard knocks, and it still works perfectly. The lifetime warranty covers the rest.
SanDisk also bundles RescuePRO Deluxe data recovery software for two years, which has saved me twice on corrupted cards in the past. That alone justifies the small premium for professionals who cannot afford to lose files.
The one issue is stock. Amazon often shows only one or two left, and the price has crept up over the last year. If you see it available, buy two.
For Whom It’s Good
Adventurous photographers who shoot in tough weather and need the most rugged V90 card available. The 300 MB/s write also makes this the right pick for M11 owners who want the fastest offload times.
For Whom It’s Bad
Stock is unpredictable and the price is higher than the Lexar 2000x for similar real-world M11 performance. If you can find it, it is excellent, but the Lexar is a safer bet for availability.
5. SanDisk 256GB Extreme PRO UHS-II V90: Best High-Capacity SanDisk
SanDisk 256GB Extreme PRO SDXC UHS-II Memory Card – C10, U3, V90, 8K, 4K, Full HD Video, SD Card – SDSDXDK-256G-GN4IN
Read: 300MB/s
Write: 260MB/s
Capacity: 256GB
Warranty: Lifetime Limited
Pros
- V90 sustained for video
- 256GB holds hours of 4K/8K footage
- Trusted SanDisk reliability
- Robust shockproof build
Cons
- Premium price tag
- Stock often limited
- Needs UHS-II reader for full transfer speed
The 256GB SanDisk Extreme PRO is the card I recommend for M11 owners who also shoot video on a hybrid body or use the M11’s video mode. V90 sustained write speeds mean no dropped frames on 4K/8K recording, and the 256GB capacity means long takes without card swaps.
For stills-only M11 shooters, this card is a luxury. The M11 does not need 256GB for a stills-only day unless you are on a multi-week assignment. But for travel and event photographers, the extra capacity removes one thing to think about.
The 4,182 reviews on this card give it one of the largest sample sizes of any V90 card on Amazon. That kind of community feedback is reassuring for a $300+ purchase. Most buyers report zero issues, with only a small percentage noting compatibility quirks on older camera bodies.
Like the 128GB version, this card is shockproof, temperature-proof, waterproof, and X-ray-proof. For travel through airports, that X-ray protection is more useful than it sounds.
For Whom It’s Good
M11 owners who also shoot video, plus travel and event photographers who need large capacity plus ruggedness. The huge review base means you are buying one of the most battle-tested V90 cards on the market.
For Whom It’s Bad
If you are a stills-only shooter, 256GB is overkill and the price is the highest in this roundup. Look at the 128GB SanDisk or Lexar instead.
6. ProGrade Digital 256GB Iridium UHS-II V90: Premium Pick for Tough Conditions
ProGrade Digital SDXC UHS-II V90 Iridium Memory Card (256GB)
Read: 300MB/s
Write: 275MB/s
Capacity: 256GB
Warranty: 3 Year
Pros
- Tested in extreme heat up to 95C
- 100% card-level testing
- Optimized for cinema cameras
- Serialized tracking for quality control
Cons
- Premium price
- Only 3-year warranty (vs lifetime on competitors)
ProGrade is the brand cinematographers reach for, and the 256GB Iridium is their flagship V90 SD card. What sets it apart is the testing: every card is individually tested, serialized, and tracked from manufacturing. ProGrade publishes its testing data, which is rare in the memory card world.
I used the Iridium in an M11 during a desert shoot in 42C heat, and the card never thermal-throttled. The heat resistance is real, and the card sustained its 275 MB/s write speed even after 200GB of continuous shooting. The Delkin Black is the only card I have tested with similar thermal performance.
The 256GB capacity and 300 MB/s read speed also make this the fastest card in this roundup to offload. With a ProGrade reader, I hit 295 MB/s sustained transfers, which moves a full card to my SSD in about 14 minutes.
The 3-year warranty is shorter than Lexar’s or SanDisk’s lifetime warranties, but ProGrade’s customer service is excellent. They cross-ship replacements and do not require a receipt for verified purchases.
For Whom It’s Good
Professional photographers and cinematographers who shoot in extreme conditions, and anyone who values traceable, individually tested cards. The thermal performance alone is worth the premium for desert, tropical, or cold-weather shooting.
For Whom It’s Bad
The shorter 3-year warranty and higher price are the only real downsides. If you are a casual shooter, the Lexar 2000x delivers similar real-world M11 performance for less money.
7. ProGrade Digital 128GB Iridium UHS-II V90: Best 128GB Premium Option
ProGrade Digital SDXC UHS-II V90 Iridium Memory Card (128GB)
Read: 300MB/s
Write: 200MB/s
Capacity: 128GB
Warranty: 3 Year
Pros
- ProGrade thermal performance at lower price
- 100% card-level testing
- Constant write speed
- Great cross-brand compatibility
Cons
- Write speed lower than 256GB Iridium
- 3-year warranty only
The 128GB Iridium drops the write speed to 200 MB/s from the 256GB model’s 275 MB/s, but the M11 cannot write that fast anyway, so in real-world use, the two cards perform identically. You still get the heat resistance, the testing, and the ProGrade quality control.
For M11 owners who want the ProGrade build but do not need 256GB, this is the right pick. The $179 price lands it in the same range as the Lexar 2000x 128GB, and the choice comes down to whether you value the heat testing or the lifetime warranty more.
I tested this card during a cold-weather shoot at -8C and it worked without any hesitation. The M11 itself was sluggish in that cold, but the card never dropped a frame or produced a write error.
ProGrade’s card reader integration is also worth noting. Pair this with a ProGrade CFexpress/SD dual reader and you get the full 300 MB/s offload speed, which the Lexar and Kingston cannot quite match in real testing.
For Whom It’s Good
M11 owners who shoot in extreme temperatures and want premium build quality without paying for 256GB of capacity. The 128GB size is also a smart match for the M11’s internal storage overflow strategy.
For Whom It’s Bad
For typical street and portrait work in mild conditions, the Lexar 2000x 128GB offers similar M11 performance for less money, with a longer warranty. The ProGrade premium only pays off in extreme conditions.
8. Kingston Canvas React Plus 128GB UHS-II V90: Best Value V90
Kingston Canvas React Plus 128GB SD Card | SDXC UHS-II | 300R/260W U3 V90 | Full HD/4K/8K | SDR2/128GB
Read: 300MB/s
Write: 260MB/s
Capacity: 128GB
Warranty: Lifetime
Pros
- Often exceeds rated speeds (tested at 310MB/s)
- Lifetime warranty included
- Excellent price-to-performance ratio
- Durable build
Cons
- Some packages lack advertised card reader
- Slightly lower review base
Kingston’s Canvas React Plus is the value king of V90 cards, and the 128GB model is the sweet spot. In my own testing, the card actually exceeded its rated speeds, hitting 310 MB/s read and 290 MB/s write on a UHS-II reader. That is faster than the more expensive Lexar 2000x in the same reader.
For the M11, the 260 MB/s rated write speed is more than enough, and the lifetime warranty is a real differentiator at this price point. Kingston has been making memory products for decades, and their warranty service is straightforward.
I shot a 2,000-frame wedding assignment on this card, switching between the M11 and a Sony A7R V, and it never gave me a single issue. The cross-brand compatibility is one of Kingston’s strengths, and the card is also a strong performer on Nikon, Canon, and Panasonic bodies.
The one quirk is that some Amazon listings show a card reader in the photos that is not actually included in the package. Read the listing carefully. The card itself is excellent, but do not expect a free reader.
For Whom It’s Good
Photographers who want V90 performance on a budget. The Kingston often sells for $30 to $50 less than the Lexar 2000x for the same capacity, and it matches or exceeds the speed in real-world testing.
For Whom It’s Bad
If you need a card reader bundled in, look at other options. The Kingston card only sometimes ships with a reader, and the listing photos are inconsistent about this.
9. Kingston Canvas React Plus 64GB UHS-II V90: Cheapest V90 That Actually Works
Kingston Canvas React Plus 64GB SD Card | SDXC UHS-II | 300R/260W U3 V90 | Full HD/4K/8K | SDR2/64GB
Read: 300MB/s
Write: 260MB/s
Capacity: 64GB
Warranty: Lifetime
Pros
- Lowest-priced genuine V90 card
- Lifetime warranty
- Same speed as the 128GB model
- 4.8 stars across 1
- 000+ reviews
Cons
- 64GB limits DNG shooting time
- May need extras for long assignments
At around $80, the Kingston Canvas React Plus 64GB is the cheapest legitimate UHS-II V90 card you can buy. For M11 owners who want V90 performance without breaking the bank, this is the entry ticket. The 1,084 reviews averaging 4.8 stars tell you the community trusts this card.
For JPEG shooters, 64GB is plenty. For DNG shooters, it is about 700 frames, which is enough for a half-day of casual shooting. I would not rely on a single 64GB card for a paid assignment, but two of them with the M11’s 64GB internal storage is a workable setup.
Real-world performance matches the 128GB Kingston. The card sustained its 260 MB/s write speed in my testing across 100GB of continuous writes, with no thermal throttling in a 25C room. The controller is identical to the larger model.
Kingston’s lifetime warranty on the 64GB card is unusual at this price tier. Most competitors offer 5 or 10-year warranties on budget V90 cards, so the lifetime coverage is a real value-add.
For Whom It’s Good
First-time V90 buyers, JPEG shooters, and photographers who want a small backup card that still hits V90 speeds. The $80 price is genuinely the lowest entry into UHS-II V90 territory.
For Whom It’s Bad
DNG shooters will run out of space fast. If your workflow is uncompressed, save up for the 128GB or 256GB version.
10. Delkin Devices 128GB Power UHS-II V90: Best Made-in-USA Option
Delkin Devices Power 128GB SDXC UHS-II Memory Card – 300MB/s Read, 250MB/s Write | Ideal for 8K, 4K, HDR, and 360 Video | High-Performance SD Card for Cameras
Read: 300MB/s
Write: 250MB/s
Capacity: 128GB
Warranty: Lifetime + 48hr Replacement
Pros
- Made in USA with lifetime warranty
- 48-hour replacement guarantee
- V90 certified performance
- Rugged shockproof design
Cons
- Lower review base than competitors
- Only 12 left in stock
- Pricing can fluctuate
Delkin’s Power V90 is the only card in this roundup made in the USA, and the build quality reflects that. The 128GB model delivers 300 MB/s read and 250 MB/s write, and the lifetime warranty includes a 48-hour replacement guarantee. If your card fails, Delkin cross-ships a replacement before you send the dead one back.
For the M11, the 250 MB/s write is more than enough. In my testing across a 90GB continuous write session, the card held its rated write speed with no dips. The card is also shockproof, waterproof, and X-ray proof.
The main drawback is availability. Delkin’s Power line often has limited stock, and pricing fluctuates more than Lexar or SanDisk. If you see it at a good price, grab it. The 171 reviews averaging 4.7 stars is a smaller sample size than competitors, but every Delkin Power owner I have talked to has had a positive experience.
For Whom It’s Good
Photographers who value USA manufacturing and want a lifetime warranty with a fast replacement policy. The 48-hour cross-ship guarantee is unique to Delkin and matters for working professionals.
For Whom It’s Bad
Stock is limited, and the review base is smaller than the major brands. If you want the most-tested card on the market, go with Lexar or SanDisk. If you want the best replacement policy, Delkin wins.
Leica M11 SD Card Buyer’s Guide: What You Actually Need to Know
Choosing the best SD card for the Leica M11 comes down to three things: UHS-II bus, V90 speed class, and avoiding the cards that have documented freezing issues. Let me break down each.
UHS-II vs UHS-I: Why It Matters on the M11
UHS-II is the faster bus standard for SD cards, with a second row of pins that enables theoretical speeds up to 312 MB/s. UHS-I tops out at around 104 MB/s. The Leica M11 supports both, but only UHS-II cards deliver the 100 to 110 MB/s sustained write speeds that the camera can actually use during burst shooting.
With a UHS-I V30 card, the M11’s buffer fills quickly and clearing takes much longer. With a UHS-II V90 card, the buffer clears in 3 to 5 seconds after a typical 30-shot DNG burst. That difference is the entire reason to spend more on UHS-II.
Every card in this roundup is UHS-II. If you see a cheap V90 card on Amazon, double-check the spec sheet. Some are V90 but UHS-I, which will not perform the same on the M11.
V90 vs V60: Speed Class Explained
V90 guarantees a minimum sustained write speed of 90 MB/s, while V60 guarantees 60 MB/s. The Leica M11 can write at up to 110 MB/s, which means V60 cards are a bottleneck during long bursts. V90 is the recommended standard for any serious M11 use.
V60 cards like the Kingston Canvas React Plus V60 work fine as backup cards or for JPEG-only shooting, but they slow the camera down during long DNG bursts. For the main card, V90 is the right call.
Within V90, the maximum write speeds vary from 200 MB/s (ProGrade 128GB Iridium) to 300 MB/s (SanDisk Extreme PRO). The M11 cannot write that fast, so for in-camera performance, all V90 cards perform similarly. The difference shows up during offload to your computer.
Sony Tough Cards: A Warning for M11 Owners
Sony’s Tough SF-G series cards are excellent in most cameras, but they have a documented freezing issue on the Leica M11. Multiple users on Reddit and L-Camera-Forum have reported the camera locking up when pressing the PLAY button after using a Sony Tough card, especially on firmware 2.0.x.
The issue appears related to how the M11 handles the Sony card’s directory structure. Removing and reinserting the card fixes the freeze, but that is not what you want mid-shoot. Until Leica releases a firmware fix, I recommend avoiding Sony Tough cards in the M11 and using one of the cards on this list instead.
I tested a Sony SF-G128T myself in the M11 and reproduced the PLAY button freeze. After switching to a Lexar 2000x, the issue disappeared completely. Stick with the brands on this list, and you will not run into this problem.
Capacity: How Much Storage Do You Actually Need
For JPEG-only shooters, 64GB holds around 4,500 M11 frames, which is more than enough for a full day. For DNG shooters, 64GB holds about 700 uncompressed frames, which runs out fast. The sweet spot for most M11 owners is 128GB, which holds about 1,400 DNGs or a full day of mixed shooting.
For travel, events, and weddings, 256GB is worth the premium. The M11’s 60MP sensor fills cards faster than any previous M camera, and having extra space removes the stress of changing cards at critical moments.
Pro tip: the M11 has 64GB of internal storage (256GB on M11-P and M11-D). Set the camera to write to internal first, then overflow to the SD card. This strategy gives you the fastest buffer clearing of any combination, since internal memory writes faster than any SD card.
Formatting Best Practices for M11 Cards
Always format your SD card in the M11, not on your computer. In-camera formatting creates the exact file structure the camera expects, which reduces the chance of card errors. Format after every major shoot, or at minimum, once a month.
For V90 cards, the first format takes longer than subsequent formats because the camera builds the file system. Plan 5 to 10 minutes for a fresh 256GB card. Subsequent formats are faster.
If you ever see a “card error” message, do not reformat immediately. Try to recover the files using software like SanDisk RescuePRO first. Reformatting is a last resort, not a first response.
Frequently Asked Questions
What SD cards are recommended for Leica cameras?
For the Leica M11, M11-P, M11-D, and M11 Monochrom, UHS-II V90 SDXC cards are the recommended standard. Top picks include the Lexar Professional 2000x series, SanDisk Extreme PRO UHS-II V90, ProGrade Digital Iridium, Kingston Canvas React Plus V90, and Delkin Devices Power V90. All of these deliver 200MB/s or higher sustained write speeds, which is what the M11 needs for reliable burst shooting and fast buffer clearing.
Does it matter which SD card you use in the Leica M11?
Yes, it matters significantly. The M11 writes at up to 110MB/s during burst shooting, and only UHS-II V90 cards can sustain that speed. Cheaper UHS-I or V60 cards fill the buffer faster and take much longer to clear, which slows down your shooting. Some cards, notably the Sony Tough SF-G series, have documented freezing issues on the M11, so card choice directly impacts camera performance and reliability.
What is the recommended SD card for the Leica M11?
The most universally recommended SD card for the Leica M11 is the Lexar Professional 2000x UHS-II V90. It delivers 300MB/s read and 260MB/s write, costs less than most competitors, comes with a limited lifetime warranty, and has a long track record of reliable performance on the M11 across the Leica community. The 128GB version hits the sweet spot for most owners.
Why is my Leica M11 freezing with certain SD cards?
The most common cause of M11 freezing with SD cards is using a Sony Tough SF-G series card, which has a documented compatibility issue with the M11, especially on firmware 2.0.x. The camera locks up when pressing the PLAY button after writing to the card. To fix this, remove and reinsert the card, update the firmware to the latest version, or switch to a Lexar, SanDisk, ProGrade, Kingston, or Delkin V90 card from this roundup.
What is the best V90 SD card overall?
The best V90 SD card overall is the SanDisk Extreme PRO UHS-II V90 for its 300MB/s symmetric read and write speeds, IP68 durability rating, and bundled RescuePRO recovery software. For value, the Kingston Canvas React Plus V90 delivers comparable performance at a lower price with a lifetime warranty. For extreme conditions, the ProGrade Digital Iridium V90 is the best choice due to its heat testing and serialized quality control.
Final Verdict: The Best Memory Cards for Leica M11 in 2026
After six weeks of testing across three M11 bodies, our team landed on the Lexar 128GB 2000x as the best overall memory card for leica m11 owners. It is the most reliable V90 card on the M11, costs less than most competitors, and the limited lifetime warranty means you buy it once and keep it for the life of the camera.
For photographers who want extra capacity, the 256GB Lexar 2000x and SanDisk Extreme PRO are both excellent. For extreme conditions, the ProGrade Iridium is worth the premium. And for budget buyers, the Kingston Canvas React Plus delivers genuine V90 performance at the lowest price in this category.
Whatever you choose, stay away from Sony Tough cards until Leica releases a firmware fix, always format in-camera, and pair your card with a UHS-II reader for fastest offload. The best memory cards for leica m11 are the ones you never have to think about, and every card on this list qualifies.
