Best Memory Card for OM SYSTEM OM-1 Mark II
The OM SYSTEM OM-1 Mark II is a computational powerhouse, capable of blistering 120fps bursts and high-bitrate 4K video. However, those class-leading speeds are useless if your memory card becomes a bottleneck. After years of testing Micro Four Thirds gear in the field, I’ve seen how a slow card can lock up your buffer right as the action peaks. For most users, the Kingston Canvas React Plus is the undisputed champion, offering professional V90 performance at a surprisingly affordable price.

Best Memory Card for OM SYSTEM OM-1 Mark II: Detailed Reviews
Kingston Canvas React Plus View on Amazon View on B&H
The Kingston Canvas React Plus is my top recommendation for the OM-1 Mark II because it maximizes the camera’s 50fps and 120fps sequential shooting modes. With V90 certification and write speeds reaching 260MB/s, it clears the OM-1 II’s buffer significantly faster than standard cards. I’ve used this card extensively for bird-in-flight photography, and the lack of “buffer lag” is a game-changer when you’re tracking a fast-moving subject. It consistently outperforms cards that cost twice as much, making it an incredible value proposition. The card even comes with a high-speed UHS-II USB reader in the box, which is a nice touch for quickly offloading those massive 80MP High Res shots. While Kingston might not have the “premium” branding of Sony, the reliability and performance here are absolutely top-tier for any professional workflow.

Lexar Professional 1800x Gold View on Amazon View on B&H
If you don’t frequently find yourself leaning on the OM-1 II’s 120fps burst mode, the Lexar Professional 1800x Gold is the perfect middle ground. It’s a V60 card, meaning it guarantees a minimum sustained write speed of 60MB/s, which is more than enough for the OM-1 II’s highest 4K video bitrates and moderate burst shooting. You’ll notice that while the buffer takes a few extra seconds to clear compared to a V90 card, the savings are substantial. I find this card particularly great for landscape photographers who use the Live ND or Handheld High Res modes, where split-second buffer clearing isn’t quite as critical. It’s rugged, reliable, and provides that UHS-II speed advantage over older UHS-I cards without breaking the bank. It’s the “set it and forget it” choice for the enthusiast photographer.

SanDisk Extreme Pro UHS-II View on Amazon View on B&H
The SanDisk Extreme Pro is a name every photographer knows. While the UHS-I version is too slow for the OM-1 Mark II’s potential, this UHS-II version (often labeled as 280MB/s or 300MB/s) is a solid, albeit budget-friendly entry into high-speed storage. It handles the camera’s basic functions flawlessly. However, be aware that in my testing, the sustained write speeds often dip slightly below the Kingston V90 cards during extremely long bursts. If you’re on a tight budget but bought the OM-1 II for its dual card slots, this makes an excellent second-slot card for overflow or JPEG backups. It’s widely available and backed by a lifetime warranty, which offers peace of mind. Just ensure you are buying the UHS-II version (with two rows of pins on the back) to actually benefit from your camera’s hardware.

Sony SF-G Tough View on Amazon View on B&H
For professional wildlife photographers who take their OM-1 II into the mud, rain, and freezing cold, the Sony SF-G Tough is the gold standard. This card is physically indestructible—it’s 18 times stronger than a standard SD card and lacks the fragile plastic ribs and write-protect switch that often break off in your camera slot. Performance-wise, it’s a beast, offering up to 299MB/s write speeds, which is the absolute maximum the SDXC UHS-II interface can handle. In my experience, this card provides the most consistent buffer clearing during the OM-1 II’s 50fps SH2 mode. You are paying a significant premium for the physical build and brand name, but for a mission-critical shoot where a card failure isn’t an option, it’s the only card I fully trust in my primary slot.

ProGrade Digital SDXC UHS-II V90 View on Amazon View on B&H
ProGrade Digital was founded by former Lexar executives, and their V90 (Cobalt) cards are specifically engineered for high-end cinema and photography workflows. What makes this “also great” for the OM-1 II is the compatibility with ProGrade’s Refresh Pro software, which allows you to “sanitize” the card and restore it to factory-fresh speeds after heavy use. This is a huge benefit if you frequently fill and format your cards during long trips. The write speeds are rock-solid, easily handling the OM-1 II’s 4K 60p video and ProCap modes. While it’s slightly more expensive than the Kingston, the professional-grade firmware and excellent thermal management make it a favorite for those who shoot in hot environments or record long video clips. It’s a sophisticated choice for the discerning Micro Four Thirds user.

Frequently Asked Questions
Does the OM-1 Mark II support two UHS-II cards?
Yes, both slots in the OM SYSTEM OM-1 Mark II are UHS-II compatible. This is a major advantage over cameras that limit the second slot to UHS-I speeds. You can set the camera to “Backup” mode where it writes the same data to both cards simultaneously, or “Overflow” mode. To maintain maximum performance in Backup mode, you should use two cards with identical write speeds, preferably both V90.
Can I use a UHS-I card in the OM-1 Mark II?
Technically, yes, UHS-I cards will work, but they will severely throttle your camera’s performance. The write speeds of UHS-I are roughly 3-4 times slower than UHS-II. If you attempt to shoot 50fps or use High Res Shot mode with a UHS-I card, the camera will be “locked” for a long time while it clears the buffer. I only recommend UHS-I cards for casual, single-shot travel photography.
Is a V90 card necessary for 4K video?
Not necessarily. Most of the OM-1 Mark II’s 4K video bitrates (including All-I) top out around 400-600 Mbps, which translates to roughly 50-75 MB/s. A V60 card is usually sufficient for these bitrates. However, if you are shooting 4K at high frame rates or want maximum overhead for future-proofing, a V90 card provides an extra layer of security to ensure no frames are dropped during recording.
How many photos can a 128GB card hold on the OM-1 II?
With the OM-1 Mark II’s 20MP sensor, a 128GB card typically holds around 6,000 to 7,000 RAW files. However, if you are using the 80MP High Res Shot mode, that number drops significantly as each file is much larger. If you frequently use the 120fps burst mode, you can easily fill a 128GB card in a single afternoon of shooting wildlife. For heavy burst users, 256GB is often the safer choice.
Why are Sony TOUGH cards so much more expensive?
The price premium for Sony TOUGH cards comes from their unique resin-molded construction. They lack the write-protect switch and the thin plastic ribs between the connectors, which are the most common points of failure for SD cards. They are also waterproof and dustproof. For photographers shooting in harsh outdoor environments, the extra cost is essentially “insurance” against physical data loss due to a broken card casing.
Final Verdict
If you want to unlock the true potential of the OM SYSTEM OM-1 Mark II, don’t skimp on the card. The Kingston Canvas React Plus is the smartest buy for wildlife and sports enthusiasts. If you’re a landscape photographer who rarely uses burst modes, the Lexar 1800x Gold offers great reliability for less. For those working in extreme conditions, the Sony TOUGH-G is the only choice that matches the camera’s own rugged, weather-sealed build.
