Joshua Waller reviews the new OM System ‘Olympus’ OM-1 Micro Four Thirds camera, with new 20MP Stacked BSI Live MOS sensor

The OM System ‘Olympus’ OM-1 is OM Digital Solutions new E-M1 III update, with a brand-new, never before seen 20MP Stacked BSI Live MOS sensor, updated body design, high-resolution OLED EVF, updated vari-angle touch-screen, and – make sure you’re sitting down – a completely redesigned menu system. Available from the beginning of March, pre-orders will get a free additional battery.

The new sensor, along with a new image processor, allows for high-speed continuous shooting, at 120fps at full-resolution, an improved ISO range, (upto ISO 102400), which OMDS say will give up to 2 stops noise improvement, as well as an extra 1 stop of dynamic range. They also say that most Micro Four Thirds users, when asked, wanted better noise performance, rather than higher resolution.

At a glance

  • £1999 body only
  • 20MP Four Thirds Stacked BSI Live MOS sensor
  • 50fps with C-AF, upto 120fps fixed AF
  • ISO80 – ISO102400 (extended)
  • 1053-point AI detect Quad Pixel AF
  • 5.76m-dot electronic viewfinder, 1.65/0.825x magnification
  • 1.62m-dot 3in vari-angle touchscreen
  • 5-axis in-body stabilisation (upto 8EV)
  • IP53 rating with specific lenses

There’s a completely new, and first to market ‘Quad Pixel AF’ system, with 1053 cross-type AF points covering the entire sensor, and this supports continuous shooting speeds upto 50fps with Continuous AF, when using a compatible Olympus PRO lens. “Quad pixel AF” divides the pixel (photodiode) into 4 subpixels underneath the colour filter, and should not be confused with Quad Bayer filter – it is NOT a Quad Bayer sensor.

AI detection AF has been improved upon from the E-M1X and now supports planes, trains, motor vehicles, birds, and animals such as cats and dogs, with both subject and face/eye detection, and this is said to be 3x faster than the E-M1X. Focus is sensitive down to -5.5 EV, and you can choose whether to have a small focus point, all the way up to the full frame, with multiple sizes and areas in-between. You can also customise the focus area, with 4 different custom groups available.

In-body Image Stabilisation (IBIS) has long been a feature of Olympus cameras, and using 5-axis Sync IS with a compatible lens will give up to 8 stops of correction. When using a non-sync lens, you can expect up to 7 stops of IS.

Beyond this, the camera also adds 1 step better rolling compensation, as well as improved panning compensation. There’s a new “Handheld assist” to support handheld long exposure shooting, which also works with Live Composite and Live Bulb.

Computational photography – the camera includes a whole new menu section dedicated to this. This is where you’ll find High-res shot, Live ND, Focus stacking, HDR, multiple exposure, plus Live composite / time / bulb mode options. These last three settings can be quickly accessed using the B setting on the mode dial.

Key Points

  • New image processor – TruePix X – 3x faster image processor than TruePic VIII / IX, giving 2x faster High-Res and Focus Stacking processing.
  • OLED EVF – The camera features a new 5.76m dot EVF with 0.83x magnification, 120fps refresh rate, blackout free shooting, and anti-fogging.
  • IP53 rating – The camera body meets the IP53 rating, and is dust and splashproof when used with splashproof PRO lens.
  • Power – The new BLX-1 battery gives a 25% increase in performance, for 520 shots per charge, and the camera supports USB-C charging as well as PD support (9V, 3A).

OM System ‘Olympus’ OM-1 Features

The new high-res OLED EVF, with 5.76m-dots, offers the same resolution as premium models such as the £5879 Canon EOS R3, and the £4000 Leica SL2-S, and a higher resolution than the Nikon Z9 (at 3.69m dots). Magnification is 1.65x (0.825x) same as E-M1X, or 1.48x (0.74x) selectable, with the same optical quality as the E-M1X, and a 120fps refresh rate. There’s an anti-fogging coating for shooting in wet conditions, and a 0.005 sec display delay.

High-res shot gives 80/50MP images, and is easier to access using the movie button in photo mode, as OMDS want to make it easier to use this feature, even when out and about, without the need for a tripod, with handheld hi-res giving 50MP images. Using the high-res shot mode also gives 2 steps better noise performance due to multiple images being combined, and images are combined automatically in-camera.

OM System OM-1 next to the Olympus OM-1

OM System OM-1 next to the Olympus OM-1, a lot has changed in 50 years.

Video recording has been improved to include Cine 4K at 60fps from 5K oversampling, with 4:2:2 10bit (H.265 codec) internal recording, and FullHD at up to 240fps (cropped).

For the more advanced, there’s also support for C4K, 60p, 4:4:4, 12-bit external recording using Apple ProRes RAW with Atomos Ninja V support. Unlimited video recording is also possible, only limited by battery life.

OM System 'Olympus' OM-1 new menus

OM System ‘Olympus’ OM-1 new menus

The camera features a completely redesigned menu system, that is now neatly colour coded, and browsable with the front and rear command wheels, or the 4-way controller. Unfortunately, they are not selectable using the touch-screen, however the Super Control Panel (SCP) is touch-sensitive for most options. Greyed out items that are not selectable are explained with a pop-up explanation explaining why, and you can also get information on each option by pressing the Info button. There’s also a MyMenu section so that you can get quick access to your favourites.


High-speed shooting – Continuous shooting buffer size:

  • 10fps: 129 shots (raw), 169 shots (JPEG LF)
  • 20fps: 108 shots (raw), 116 shots (JPEG LF)
  • 120Fps: 92 shots (raw or JPEG LF)

Pro Capture lets you capture 70 pre-shot images, double that of E-M1 III/E-M1x.


Shutter life is rated to 400,000 shots (when using the mechanical shutter), and we expect an unlimited number of shots can be taken when using the electronic shutter.

The IP53 rating is an improvement over the IPX1 rating of the E-M1 III, and the camera is dustproof, splashproof, and freezeproof with a lightweight magnesium alloy body. To benefit from the IP53 rating you need to ensure you use compatible lenses.

It almost goes without saying, that the camera features Wi-Fi, and Bluetooth built-in for remote connections and control with your smartphone or tablet. You can also use the camera as a very high quality webcam if you want, using Olympus’s free webcam software.


Some of the differences between the OM-1 vs E-M1 III / E-M1X

  • Additional 1stop added to Live ND, now upto ND64
  • 1053 AF points vs 121 (E-M1 III / E-M1X)
  • Upto 8 stops IS (vs 7.5 E-M1 III, sync IS)
  • 3inch touchscreen with 1.62m dots (up from 1.04m)
  • 5.76m-dot EVF 0.83x magnification (vs 2.36m-dots, 0.74x on E-M1 III)
  • 50fps C-AF, or 25fps C-AF depending on lens, vs 18fps C-AF on E-M1 III
  • Improved Pro Capture – now 70 shots before you shoot!
  • 2x faster High-Res and Focus Stacking processing
  • TruePix X – 3x faster image processor than TruePic VIII / IX

See our detailed OM-1 vs E-M1 III comparison for more details.


OM System ‘Olympus’ OM-1 Design and handling

The OM-1 will look familiar to anyone who has used E-M1 cameras, but there are a few subtle changes that are designed to make the camera easier to use, including a new AF-ON button on the back of the camera, a smaller function lever (switches between AF and MF), as well as redesigned command dials at the front and back. The shutter release button is now separate to the command wheel, and the hand grip gives an excellent feel, helping the camera feel great in the hand.

The controls are all neatly positioned to make them easy to reach, and you have direct access to the most important settings, with dedicated ISO, Exposure compensation, and AF-ON buttons. There’s a dedicated video record button, and the majority of buttons and controls can be customised to your own personal preferences. The ISO button also doubles as image rating button in playback, so you can quickly give images a star rating out of 5.

The camera body has a solid metal construction, and with multiple seals it offers improved weather-sealing than other Olympus cameras, being the first to offer an IP53 rating being both dust and splashproof when used with specific PRO lenses. The camera is ever so slightly larger than the E-M1 III, at 134.8 x 91.6 x 72.7mm, and weight is slightly increased, at 599g with battery and memory card (excluding eyecup).

The battery compartment is found underneath, and features a metal latch that locks firmly into place. You can see there are good levels of weather sealing, and it’s possible to open the battery compartment even when using a relatively large tripod plate. The new battery, model BLX-1, has a rating of 2280mAh (7.2V), which is an improvement over the 1720mAh (BLH-1) battery used in the E-M1 III. Using the Quick sleep mode is said to double battery life, and the new, optional HLD-10 battery grip can also double battery life.

In a long awaited update, the menus have been completely redesigned, and they look great, being logically laid out, with clear colour coded sections, browsable with the front and rear command wheels, or the 4-way controller. Unfortunately, they are not selectable using the touch-screen, however the Super Control Panel is touch-sensitive for most of the options. There’s also a MyMenu section so that you can get quick access to your favourites.

Viewfinder and Screen

OM System Olympus OM-1 rear

OM System Olympus OM-1 rear

The electronic viewfinder (EVF) looks great, with a high-resolution OLED display at 5.76m-dots, it gives a very clear view, and the optics used are also of high quality, giving you a sharp view right into the corners. Icons and text are clearly displayed, and you can access the menus and Super Control Panel if needed to change settings. You get the choice of 0.83x magnification, filling the frame, or 0.74x if 0.83x is too large. The optics have an anti-fogging coating, to help with visibility when using it in inclement weather, and there’s a 120fps / 0.005s refresh rate.

You’ll also find that you can shoot at 120 or 50fps without blackout, and this really is useful when you want to ensure you’re still capturing the subject, and the AF-tracking is doing its job (at 50fps).

A simulated OVF (optical viewfinder) view is available, or S-OVF, and this is designed to give you a view more similar to using an optical viewfinder. A new “Night Vision” option has been added to support astrophotography, and this is designed to work with the “Starry Sky AF” setting.

OM System Olympus OM-1 touchscreen

OM System Olympus OM-1 full articulated 3inch touchscreen

There’s a 3inch 1.62m-dot touch-screen, which is fully articulating, and can be tilted out to face forwards, great for selfie’s, vlogging, and other things. The view is very clear, and colours look great, matching the viewfinder. The screen also has good viewing angles, and it’s also bright enough outdoors, with adjustable brightness levels. The microphone socket can be used without the screen bumping into it, due to a higher position.

Some of the icons appear a little bit small at times on the rear screen, and this would benefit from an update, even making the icons just a little bit larger would help. For example, the multi-shot high-res shooting mode is shown with a small icon, as is the AF AI detection mode selected.

AUTOFOCUS

With the AF-ON button on the back, the camera can be used in the same way as other cameras with this, and for those that love to use ‘back-button focus’ this will be a real bonus.

You can customise the AF area, and whilst there are numerous areas already setup, you can customise and setup four different, additional focus areas. AF settings can be quickly accessed with one of the many dedicated AF buttons, and pressing the top left AF/metering button gives you access to metering options, as well as AF modes including: S-AF, C-AF, MF, C-AF + Tracking, Preset MF, and Starry Sky AF.

Cat Detection AF on the OM-1

Cat Detection AF on the OM-1, 1/60s, f/2.8, ISO800, 26mm (12-40mm F2.8 PRO II)

AI subject detection gives you the choice of motorsports (cars, motorcycles), airplanes (including helicopters), trains (of all types), birds, and animals – specifically cats and dogs. When you’re not focusing on these subjects, then the camera will also focus on humans, with face and eye detection AF, which is extremely rapid.

Bird AF on the OM-1

Bird AF on the OM-1, 1/320s, f/4, ISO1000, 160mm (40-150mm F2.8 with 1.4x TC)

Subject detection requires you to choose the subject before shooting, however this can be set to a custom function button to make it quicker to switch subjects. Using this you can see the camera quickly track the subject, as well as the main area also highlighted with a smaller box, for example the head/face and eyes of a subject, even when the subject is looking away.

It’s worthwhile customising a button for this, or adding it to the MyMenu section, as it can take a while to find this option otherwise, as it doesn’t appear to be accessible on the Super Control Panel (perhaps a firmware update will add this).

Low-light gig AF, OM-1

Low-light gig AF, 1/80s, f/2.8, ISO3200, -0.7EV, 38mm (12-40mm F2.8 PRO II)

Starry Sky AF – This AF options works well to help you capture photos of stars at night, with the camera focusing correctly on the distant stars.

There’s an option to automatically create timelapse videos in-camera that you could use in conjunction with this, with a wealth of settings (including 4K, FullHD video output). You also get to set the interval time from 1 second, up to 24hrs, 59m, 59seconds, and can take up to 9999 shots!

OM System ‘Olympus’ OM-1 Performance

Lucy Woodroffe, Portrait, with OM-1, raw to JPEG conversion using OM Workspace, 1/80s, f/2.8, ISO500, 35mm (12-40mm F2.8 PRO II)

Image quality and detail is excellent, particularly at lower ISO speeds, with a noticeable improvement to be found in the levels of detail visible in images. In fact, depending on your subject, you may want to reduce the sharpness slightly particularly with portraits, depending on the lens you use.

Coffee Cup with OM-1

Coffee Cup with OM-1, 1/60s, f/2.8, ISO800, 32mm (12-40mm F2.8 PRO II)

The new OM System M.Zuiko Digital ED 12-40mm F2.8 II PRO lens gives excellent images, with rapid focus and extremely sharp results. It’s been updated to improve image quality, and weather-resistance, as well as a new fluorine coating. The lens performs extremely well, and has an impressively close focus distance.

Colour is, as you would expect with an ‘Olympus’ camera, very pleasing, Olympus cameras have always given great colour reproduction, thanks to an excellent auto white balance system. There are multiple picture modes (or profiles) to choose from, and you can customise the sharpness, contrast, saturation, and gradation of each to your own personal preferences, if needed, and I’m only saying ‘if needed’ as for the most part you won’t need to as the camera gives excellent results straight from the camera.

Handheld IS shot, low-light

Handheld IS shot, low-light, OM-1, 1/15s, f/2.8, ISO1000, -0.7EV, 22mm (12-40mm F2.8 PRO II)

Image stabilisation performance – The image stabilisation system is excellent, however, the camera, on default settings tends to raise the ISO and shutter speeds, so if you’re happy to use the IS system more, rather than rely on higher ISO/shutter speeds, then it’s worth adjusting the settings. Then you should be able to get sharp shots at much slower shutter speeds than you would with other camera systems, giving you the benefit of lower noise (and cleaner detail) in images, assuming you’re not shooting moving subjects.

High-res multi-shot mode (20mp, 50mp, 80mp crops)

High-res multi-shot mode (20MP, 50MP, 80MP crops) Click to view full-size crop.

High-res 50MP/80MP modes – In the normal photo modes, holding the movie record button and turning the rear dial lets you switch on the high-res mode, as well as switch between handheld and tripod modes. The camera combines multiple shots in camera, producing a higher resolution image, with 50MP images possible handheld, and 80MP images when using a tripod. Processing speeds have been improved, taking roughly 5 seconds, meaning you can more quickly move on to your next shot.

High-res multi-shot image with OM-1

High-res multi-shot image with OM-1, 1/400s, f/7.1, ISO200, 12mm (12-40mm F2.8 PRO II), 20MP: Here, 50MP: Here (21MB), 80MP: Here (34MB).

The results possible are impressive, with additional detail visible thanks to a higher resolution image, however, any movement in the scene, such as trees blowing in the wind may degrade the image quality in these areas.

Pro Capture – Shooting at 120fps is all well and good, if you like shooting lots of shots and hoping you captured the right thing, however, your reaction times need to be really good if something unexpected happens. That’s where Pro Capture comes in, letting you capture up to 70 shots before you press the shutter release button. This makes it a really useful feature, as you can be more confident of getting the action, and can often shoot less, rather than other cameras, where you have to start shooting, and hope the action happens while your camera still has enough buffer to store all the shots without slowing down.

Like the other high-speed shooting options, you can shoot at 120fps (ProCap SH1) with fixed AF/AE, or at upto 50fps (ProCap SH2) with C-AF/AE tracking with the right lens. You’ll need to ensure light levels are good though, as the shutter speed needed for this is 1/640s.

ISO and Noise Performance

ISO200, 1/2sec, f/6.3, ISO200, 12-40mm @ 35mm, click to enlarge, OM-1

The camera has made improvements in noise performance, with both a BSI CMOS sensor (BSI CMOS sensors give improved noise performance compared to CMOS sensors), and the camera also adds a new AI algorithm for noise reduction. These images are crops from JPEGs straight from the camera, and you can click them to view the full-size versions.

ISO6400, 1/80sec, f/6.3, ISO6400, 12-40mm @ 35mm, click to enlarge, OM-1

OMDS say the standard range of the OM-1 is ISO200 to ISO25600, with ISO80, and ISO100 being extended (low) settings, and above ISO25600 being extended (high) settings, going all the way up to ISO102400. This is a noticeable improvement over the standard range of ISO200 to ISO6400 on the E-M1 III.

ISO12800, 1/160sec, f/6.3, ISO12800, 12-40mm @ 35mm

While ISO6400 felt like the limit on the E-M1 III, we’d say that using ISO12800 and ISO25600 on the OM-1 produces improved results. Whilst ISO25600 on the Olympus PEN E-P7 showed image quality drop off noticeably, the OM-1 delivers better results, with JPEG images looking good, albeit with an obvious drop in detail as the ISO speed increases.

ISO25600, 1/320sec, f/6.3, ISO25600, 12-40mm @ 35mm, click to enlarge, OM-1

Whether you’ll want to shoot at these higher ISO speeds will be up to you, and of course, processing the raw files, you can adjust the noise reduction settings to suit.

Images show excellent detail, particularly fine detail at lower ISO speeds, particularly when using a high-quality lens like the 12-40mm f2.8 PRO lens, however, with a base ISO speed of ISO200, the extended speeds of ISO80 and ISO100 do show a reduced dynamic range.

It’s nice to see a Micro Four Thirds camera offering a competitive ISO range, making it more competitive with APS-C cameras.

You can also process raw images in-camera, to adjust the noise reduction options (Off, Low, Standard, High), or use Olympus Workspace, which has been updated to include an AI Noise reduction tool. The raw .ORF files are also supported in the latest version of Adobe Camera Raw.

However, one area where this camera lags behind is in resolution, with a 20MP sensor, it simply doesn’t match other cameras that offer 24/36/42/45/50MP sensors. Yes, you can use the high-res modes for still subjects, but not everyone wants to shoot still subjects. No doubt, if this camera did offer a higher resolution sensor, we’d have a more limited ISO range, and mostly likely be complaining about noise performance, so ultimately it’s good to see an extended ISO range, even if it does mean we have a 20MP sensor.

Video performance

Unlimited 4K 60fps video is available, with options for CINE 4K or UHD, with AF including face/eye detection. High-speed FullHD video can be recorded at speeds upto 240fps (8-bit), or 200fps (10-bit), albeit without sound, and S-AF (pre-record) / MF.

OM-Log400, Flat and HLG video picture mode profiles are included, as well as the same colour profiles as the photo mode, however options are limited depending on H.264/H.265 selection, with photo profile, Flat and OM-Log400 available with H.264 (8-bit), and OM-Log400 and HLG (Hybrid Log Gamma) available with H.265 (10-bit). View Assist is available and displays a standard BT.709 colour gamut onscreen.

Audio is recorded at 16-bit, 48KHz, or 24-bit, 96KHz, with options for wind noise reduction, volume limiter, plus separate levels for internal / external mic, along with settings for plug-in power, and headphone volume settings. H.264 video has a maximum bitrate of 202mbps, and H.265, with more efficient compression has a maximum bitrate of 152mbps.

Detail in video footage is good, and the camera’s in-body image stabilisation gives impressive levels of stabilisation that can give your video the look of a system using gimbal stabilisation.

There are microphone and headphone sockets as you’d expect, as well as PD (Power Delivery) over USB Type-C, however, one thing that will most likely disappoint videographers is the micro HDMI connection.

Zebra display with two levels is available, plus a red frame around the screen when recording.

Value for money

Competitors to the OM-1 include the following APS-C and Micro Four Thirds models:

There’s also the Panasonic Lumix G9, Olympus OM-D E-M1 III, and E-M1X which all offer 60fps continuous shooting.

Full-frame models with a similar price point include:

However, it’s extremely difficult to find other cameras that offer such high-speed continuous shooting as the OM-1, without increasing the price massively, with the closest being the £5299 Nikon Z9, which offers 120fps continuous shooting at 11MP, or 30fps at 47MP.

OM System ‘Olympus’ OM-1 Verdict

The new OM System ‘Olympus’ OM-1 gives Micro Four Thirds users and fans the latest technology as well as a long-overdue, and long-wished for BSI Stacked Live MOS sensor, giving users a step up in image quality and noise performance, something that has been lagging behind other cameras, who have featured BSI CMOS sensors for several years now*.

It also re-introduces the OM-1 name, in recognition of the 50th anniversary of the original OM-1. The new name dramatically simplifies the long-winded and often confusing naming system found on previous Olympus cameras. However, this is tinged with a bitter-sweet sorrow, as this is the last camera to bear the Olympus branding, and the official name of the camera is OM System OM-1.

If you enjoy shooting with Olympus cameras, then the refinements made with the OM-1, along with the improved image quality, features, and improved video options, makes this camera a real joy to use, with the updated menu systems another welcome change.

Without doubt, the OM System OM-1 is the best Micro Four Thirds camera currently available, and goes beyond what you would expect from a £2000 camera in terms of subject detection AF, high-speed performance, and the sheer number of useful shooting features available.

The camera also resolves the complaints we made about the E-M1 III, with a new high-resolution viewfinder that looks fantastic, improved screen, improved menus, and the vertical grip now has a joystick. There’s also improved battery life, dramatically improved AF, and a noticeable improvement in image quality.

For fans of smaller mirrorless camera systems, the OM-1 offers a really compelling option, particularly when you factor in the range of compact Micro Four Thirds lenses available for it. There will be those that want a full-frame sensor, but by sticking with Micro Four Thirds, OMDS has been able to create a relatively compact, weather-sealed camera system, with a vast choice of matching size lenses. They’re also able to use this to their advantage, with an ultra-high-speed sensor.

Yes, full-frame mirrorless cameras are also quite compact, but are the lenses? And if you want high-speed, you’re looking at a significantly larger, and more expensive system.

The price has gone up, to just under £2000, which makes it £400 more expensive than the E-M1 III was when it was released, but many other cameras have also increased in price, as fewer cameras are being sold.

For those that need or want 120fps continuous shooting (at 20MP), or 50fps with continuous-AF, this camera really does offer some unique features, including Pro Capture, particularly when you consider the weight savings to be found, and the price difference between this and other high-speed cameras such as the Sony A1, Canon R3, and Nikon Z9. The OM-1 weighs in at around 985g with the 12-40mm F2.8 II lens, and the 40-150mm f2.8 with 1.4x TC weighs 1010g, giving a total weight of under 2Kg.

The improvement in weather-sealing gives this camera real appeal when you want a camera system that can be used in all kinds of weather, rather than being left at home, as long as you pair the camera with the appropriate splashproof lens.
