The Adventurer's Flagship
At the crossroads of image quality, portability, speed, and reliability, the OM-1, from OM SYSTEM is a flagship mirrorless camera built for adventure. Characterized by its versatile Micro Four Thirds platform, the OM-1 meshes quick and nimble stills performance and apt 4K video recording with unique computational imaging tools and a hardy, dependable physical design.
20MP Stacked Sensor and TruePic X
Micro Four Thirds BSI Live MOS Sensor
Newly designed 20.4MP Micro Four Thirds Live MOS sensor features a stacked BSI design that offers improved readout speeds, noise levels, and greater dynamic range than previous designs. This sensor structure improves noise performance by two stops and dynamic range by one stop for improved image quality, especially at higher ISOs.
TruePic X Processor
Compared to previous-generation processors, the TruePic X offers 3x-faster processing speeds along with a 120 fps sensor readout rate for faster, more responsive shooting. The processor also contributes to a wide ISO range and quick continuous shooting rates:

  • Native sensitivity range from ISO 200-102400, expandable down to ISO 80.
  • Continuous shooting up to 10 fps with full-time AF/AE and a buffer of 169 raw frames when working with a mechanical shutter.
  • If working with a silent electronic shutter, 20 fps shooting is possible with full-time AF/AE and a buffer of 108 raw frames. SH1 and SH2 are blackout-free high-speed shooting modes, offering rates up to 120 fps without AF/AE in SH1 and 50 fps with AF/AE in SH2.
  • Pro Capture mode begins recording before you release the shutter; able to record at 120 fps with fixed focus or 50 fps with continuous AF, this mode begins recording once the shutter button is half-pressed and then stops once the button has been fully pressed. Up to 70 additional frames can be recorded with this mode, serving as a safeguard for times when the action occurs just before you press the shutter button.
Cross Quad Pixel AF and AI Detection
Featuring a unique design, on-sensor phase-detection AF uses a Cross Quad Pixel system that effectively splits each pixel into four sub-pixels for cross-sensor performance that is more adept at focusing in tricky lighting conditions. The focusing system has 1053 individual points, which fully cover the sensor and perform at up to 120 fps to suit virtually all recording methods.

Benefitting from the Cross Quad Pixel AF structure, color and contrast information from the sensor can also be used to create a detailed depth map of the image for more refined subject detection and tracking accuracy. Using AI, this focusing system can automatically detect a range of subject types, like cars, motorcycles, airplanes, helicopters, trains, birds, dogs, cats, and humans, as well as faces and eyes. And, compared to earlier iterations of this focusing system, improved processing now makes focusing performance 2x more accurate and 3x faster.

Image Stabilization and Computational Photography
5-Axis Image Stabilization
In-body 5-axis image stabilization compensates for up to 8 stops of camera shake, allowing for the use of significantly longer shutter speeds when shooting handheld. This advanced sensor-shift system compensates for 7 stops of camera shake with the body alone, and an additional stop is provided when select IS-enabled lenses are attached.

Handheld Assist relies on this stabilization technology for more stable framing, which is especially helpful when working with longer focal length lenses. Additional, in-body image stabilization also contributes to a variety of additional shooting modes and camera functions, including High Res Shot modes, Handheld Live Composite, and an advanced dust reduction system.

Creative Shooting Modes
  • High Res Shot—Benefitted by the stacked sensor design, processing power, and image stabilization system, this mode composites a series of 12 shots into a single higher resolution frame in just 5 seconds. Tripod High Res Shots mode produces an 80MP raw file and Handheld High Res Shot mode produces a 50MP raw file, and both modes offer up to 2 stops of reduced noise and improved color information.
  • Live ND—Now supporting up to ND64 (6-stop), this unique function digitally simulates the effects of an optical neutral density filter for produce long exposure/slow shutter speed effects.
  • Live Composite—Perfect for long exposures, nighttime shooting, and light painting applications, this unique mode gradually builds up an exposure over time without overexposing key elements within the frame. This mode works to only record newly detected light sources over time, and allows live view monitoring as an image develops. A Handheld Live Composite mode is available, too.
  • Focus Stacking—This mode automatically records 15 sequential frames while shifting the plane of focus slightly between each frame, then composites these exposures into a single image that exhibits an extended depth of field.
DCI/UHD 4K Video Recording
  • DCI/UHD 4K video recording is supported at up to 60p and 10-bit 4:2:0 sampling. Full HD recording is possible at high-speed rates up to 240 fps for slow-motion playback.
  • 12-bit raw output is supported via the micro-HDMI port when working with an optional compatible external recorder, such as the Atomos Ninja V or Ninja V+.
  • HLG picture mode permits in-camera HDR recording and an OM-Log gamma allows for greater color grading range when adjusting the footage in post-production.
  • In-camera time-lapse production is possible, up to UHD 4K with frame rates from 5 fps to 30 fps.
  • Both 3.5mm microphone and headphone ports contribute to greater audio recording control and quality.
Reliable, Adventure-Ready Design
EVF and LCD
  • Electronic viewfinder features a 5.76m-dot OLED panel, offering a bright and clean means for eye-level monitoring. The finder has a 0.83x-equivalent magnification, a 21mm eye point, and 120 fps refresh rate for realistic motion rendering.
  • 3.0" 1.62m-dot LCD touchscreen features a vari-angle design with 270° of swivel to suit working from high, low, and front-facing angles.
Durable, Weather-Sealed Build
  • Lightweight, durable magnesium alloy body design is dust- and splash-resistant with an IP53 rating for ensured use in trying weather conditions.
  • Tough design is also freezeproof-tested for reliable use in temperatures down to 14°F.
  • Durable shutter design is rated for 400,000 shutter actuations.
Practical and Intuitive Handling
  • Utilizing the new BLX-1 battery, the OM-1 is rated for 520 shots per charge. In-body battery charging is possible via the USB type-C port, and the camera itself can also be powered using a USB-connected power bank.
  • Dual UHS-II SD memory card slots for flexible file saving, including making in-camera backups, splitting file types, or just for having additional memory on hand for overflow storage.
  • Updated menu configuration makes it easier to find different settings, confirm settings selections, and understand why grayed-out items cannot be selected.
  • Separate AEL and AF-ON buttons for easier, more direct control over the different functions. Both buttons can also be customized to adjust different settings.
  • Bluetooth and Wi-Fi (5 and 2.4GHz) allow wireless file transferring and remote control over the camera via the OI.Share app for mobile devices.

OM SYSTEM OM-1 Reviews

Excellent high ISO, awkward grip

By William B
Rated 3 out of 5
Date: 2023-01-26

Added an OM-1 to our two E-M1mk3. Using the same settings (AF-S, single point AF), little difference re AF. (We didn't explore other AF settings.) Deeper grip and/or strange angle of grip + shutter button was extremely uncomfortable (wrist pain). After two brief uses (indoors and outdoors), we sold the camera-solely due to the hand / wrist issues. Excellent high ISO response means less use of DeNoise, etc.

Great video camera

By John
Rated 4 out of 5
Date: 2023-01-08

We bought a pair of these 6 months ago for shooting video interviews. They record great HLG 10-bit video in 4K resolution minimally compressed via H.265 (HEVC). This gives a very nice latitude for color grading and matching in editing and finishing. Camera can easily record continuously for over 1.5 hours at a time in the above 4K HDR mode. Finally the micro four-thirds sensor size better matches the human eye to give more realistic depth of field unlike that of the larger sensor sizes.

Camera would blackout after 10-20 regular shots in 2-3 min (non-continuous). Dark screen with telemetry on (no drive activity icon). No direct sun shots. Locks even indoors. After 5 mins it would let me shoot again. I changed memory cards, updated firmware, reset to default settings. Returned

The perfect tool for Birding?

By Frank
Rated 5 out of 5
Date: 2022-12-24

Quick Background ..I still own Full frames (canon 1DXii, Sony A7R4, etc and 3 different Olympus bodies (EM1mk2, EM1X and OM-1) along side a few APC (sony 6300,6600 and Fuji x100v), plus some others. The OM-1 so far has excedded my expections when compared to the EM1X or other full frames for Birds in Flight (BIF). I'm not sure the hype is necessarily accurate regarding the dynamic range increase (I can't see it) but the nooise handling is better than the EM1X (evolutionary) but, really noticeable when compared againts the MK2. But, when you compare the performnce for Birds in flight.. it's just amazing. Crushes even the Sony A7R4...and delivers in rain, fog or low contrast. the ergonomics is where it falls short when compared to the EM1X, even with the HLD (battery grip). You are losing some buttons. The handheld pixel shift for higher resolution is barely usable for Wildlife and I mapped that button to strickly video. The battery is understated and I easily get over 1500 captures with some videos out of a single battery. But, if you use pro Capture..I get about 900. Overall the OM-1 is just an amazing tool for Birding and I highly reccomend it!!!

Worthwhile upgrade from the EM-1 Mk III

By Mark
Rated 5 out of 5
Date: 2022-12-22

I hesitated to upgrade my MkIII because it is such a great camera. I have been a Nikon user for 30 years, and I finally changed over from my D-810 to the Em-1 a year ago. The Nikon is a great camera also, but it is cumbersome, heavy, and lacks most of the added features found on the OM cameras. The Nikon sitis on the shelf 90% of the time now. I use the hand held high res mode a lot for landscapes, and it makes the OM-1 nearly as capable as the D-810 for that purpose. The fact the it processes more than twice the speed as the MkIII is a major plus for me. I also have found the noise levels are slightly lower across the board compared to the MkIII. Where the MkIII gave me great images up to ISO3200, the OM-1 is very usable up to ISO6400. That little bit helps in lower light images. Overall, I was a bit disappointed that they did not increase the sensor to 24MP, but I can live with the 20MP. I just have to avoid a lot of cropping. The build quality is great, but not to the same level as the MkIII. The front and rear dials are not as easy to use, and I miss the top mounted front dial the most. The lack of a charger is also a negative, and I feel OM Systems should have included it on their top of the line camera. Other than that, I am very pleased with the upgrade.

Still refining setup

By Nicholas
Rated 5 out of 5
Date: 2022-12-21

I am pleased with the camera, and happy with early results in photographing birds. Images seem a bit better and higher ISO results are superior to the OMD III which was good. While the two cameras are very similar in setup and function, there is some difference in feel on button placement for back button focus and on the two wheels. Overall, I am glad I made the purchase.

This OM-1 Seems Like My First Real Camera

By Charles
Rated 5 out of 5
Date: 2023-01-13

I've been through several cameras in my life. Canon AE-1, Sony S3-IS and Panasonic G85. I started looking at cameras for another reason and realized that the technology had come a very long way since I got my G85. I shoot mostly birds/wildlife, flowers and plants and landscapes. When I found that the OM-1 had intelligent subject tracking for birds that would let me keep them focused in flight, I was really intrigued. When I found out about the ProShot feature where I can can pictures from a couple of seconds before action, I was amazed! Then there was High Res and a much better Focus Stacking than my G85! I was already pretty well invested in lenses and accessories for the Micro 4/3 platform so I didn't need any new lenses. The OM-1 for me is a win-win-win purchase. I expect to get many years of good use out of it. I keep learning new features every day.

Disappointed

By Matt
Rated 2 out of 5
Date: 2023-01-12

First off, ergonomics are bad. The buttons are much smaller than EM1.3. The dials are very hard to use, the front dial is really a chore (if you wear gloves, forgetaboutit). There are a lot of reports of dials failing (in a camera that's less than a year old). Computational features are mediocre. Subject detection is not reliable. I find it's helpful about 1/2 the time. The Live ND is not strong enough to avoid carrying a filter if you shoot in sunlight. Works fine if you are only shooting in shade. Still looks fake though. Yes, people are getting great shots but only by shooting a lot and choosing the best of their hundreds of images. Who wants spray and pray? I've had some software glitches and done a few factory resets - which I've never had to do on any other digital camera. Hopefully OMS will do better next time.
