The New OM-1: Impressed by the Specs? Here's my Hands-on Review of the Camera

The New OM-1: Impressed by the Specs? Here's my Hands-on Review of the Camera

I aggressively tested an OM System OM-1 Camera in the field. As I had pre-ordered one, I was hoping that I would be pleased with the results. Was I? Here are my thoughts on the camera and what it means to the future of the OM System.

First Impressions of the OM-1

I first trained in an engineering background. Consequently, I have always had a penchant for well-made precision instruments. When I lifted this camera from the box, my very first realization of the OM System OM-1 was how well it fits that bill; it looks and feels like a high-quality device, making it a pleasure to hold and use.

It’s slightly larger than my Olympus OM-D E-M1 Mark II – I didn’t upgrade to the Mark III – and the grip is deeper than any of the E-M1 models, making it easier to hold. The bodywork feels even more robust than my previous camera, and that survived all sorts of drops onto rocks, splashes by the sea, and dunking in rivers. Despite being only a tiny bit heavier, weighing in at just 1.32 lb (599 g), the new model gives the impression of being even tougher than both its predecessors and its competition.

Portability and Battery Life: The OM-1 is the Perfect Tough Traveling Light Camera

Despite that small increase in dimensions, It’s still a small camera. The big advantage of Micro Four Thirds is that smaller size, especially because of the highly regarded OM System M.Zuiko lenses. I often walk with my camera attached to a wrist strap. With the 12-40 f/2.8 lens attached, it’s still just small enough to slide into my coat’s side pocket.

Moreover, I have family and friends dotted around the world. When I take my camera with me, I want it in my hand luggage, so it’s perfect for traveling. Furthermore, the OM System’s discreet design is especially useful in those places where you don’t want to draw attention to yourself.

Much of the time though, I just carry my camera attached to my tripod, with an ND filter in one pocket and a spare battery in the other. I don't haul bulky camera bags around. I plan my shots, taking only what I need. Now, I can sometimes even leave my pockets empty as the camera has a built-in 6-stop ND filter. The battery’s charge longevity is great too, so I don’t need to take a spare one of those.

My old camera’s battery would run down when shooting multiple long exposures, or spending a few hours capturing wildlife. With the OM1, I came home from the first 2-hour test shoot with over 1000 photographs taken over two hours. The battery had only dropped from 90% to 70% charge.

Moreover, further tests showed that the in-body image stabilization is so good, I can even leave the tripod at home for many shoots; Olympus were always ahead of the stabilization game.

The in-camera USB charging is another attribute useful dimension for travelers.

With that size and weight saving, coupled with the IP53 rating, I can see this camera appealing to outdoor activities enthusiasts where weight and durability count. IP means ingress protection, the 5 means protection from dust, and the 3 is spraying water. In other words, it should stand up to desert and rainforest conditions. Its freeze proof rating means it is reliable in use for temperatures down to 14°F (-10° C), so great in winter conditions too.

Oops! I Shot it Again, and Again, and Again

I should explain those 1000 shots. In my rush to set the camera up the night before, I had accidentally programmed one of my custom modes to Pro Capture. This recorded seventy images to the buffer before I had fully depressed the shutter release, when it loaded them onto the memory card. It then continued recording at 120 frames per second once I fully pressed that button. Lesson learned; I’ve since set the frame count limiter and slowed the frame rate. Nonetheless, it did mean that I got the shot.

I ended up with around ninety images of this female eider that suddenly stood up and shook its wings. Pro capture meant I got the shot.

As I shoot in silent mode most of the time, saving the very generous 400,000 shutter life, one big difference I noticed was the lack of blackout between frames when shooting at the fastest frame rate. This is a good thing, although I did wonder whether the camera was taking photos at first.

The OM-1's Ergonomics and Usability

As I mentioned, I graduated to this camera from the E-M1 Mark II and not the Mark III, and I noticed a marked difference in the positioning of the buttons. For users of the Mark III this will be less of a challenge, although the front dial is now recessed in the body, as opposed to sitting on top, and the top buttons by the power switch have a lower profile too. My muscle memory is still learning these new positions. The AF-On button is new to this camera and, until I got used to it, my right thumb went automatically to the AEL button to back-button focus.

But the important thing for me is that it is comfortable to hold in my big hands. Despite the diminutive size of the camera, my long fingers can easily manipulate the buttons.

Shooting with gloves wasn’t a problem. However, I do wear warm, tight fitting technical gloves made for extreme outdoor pursuits. Loose fitting, thick gloves may be a hindrance, but the same could be said of using any camera.

Putting the OM-1 to the Focussing Test

The focusing is fast and accurate and there are several factors at play here.

Geeky photographers like me will want to discover why the Quad Pixel system with 1053 cross type phase detection points that cover the entire stacked sensor make a difference. I suspect most photographers though will just be impressed that it does. Although that technical jargon sounds remarkable, you don't have to know how the auto focus works to discover that it does, and does it well.

Most of my work is shooting seascapes, so that focusing speed is less important to me, but being able to focus at the extremes of the frame is a boon. Yet, I also enjoy capturing photos of birds, and I did notice a significant improvement in focussing speed, even when using my old Four Thirds Zuiko 50-200 mm 1:2.8-3.5 SWD lens.

Even when fitted with my legacy 50-200 mm Four Thirds lens, there was a marked difference in the speed and accuracy of focussing on birds

Switching on the subject recognition feature, my success rate for capturing birds leaped up enormously. Then, using the in-body focus limiter, which allows setting three different distance ranges anywhere between 0 to 999.9 meters, I could restrict the minimum and maximum subject distance, thus reducing focusing time even more.

My previous camera's tracking would not have managed to stay locked onto this bird against that cluttered background.

The AI subject recognition is first class. It quickly detects subjects and holds focus. Even when photographing sparrows in my back yard, the camera locked onto birds even when partially obscured by the twigs and leaves of my neighbor's tree.

The AI quickly locked onto the sparrow in the tree, partially obscured by twigs, and maintained that focus even when a second bird hopped onto the frame.

It would even identify and lock onto birds that were too distant to photograph, great when capturing birds flying towards you.

Although small and distant - around 100 yards - the camera identified this pigeon and stayed locked onto it.

In single autofocus mode (S-AF), the camera mainly uses contrast-detect. I guess this is because, no matter the camera, contrast detection is more accurate. That accuracy is especially important for close-up and macro photography. I use the word “mainly” as it is supported by the phase-detect system, which I presume is to add extra speed, and also enabling focusing in low-contrast situations. 

In continuous autofocus (C-AF) it uses solely the faster phase detection system, essential when shooting moving subjects.

Close-up the focus tracking worked perfectly.

Are the Noise Control and Dynamic Range Better?

The new OM-1 has much, much better noise control than previous models, two stops in fact, and this is noticeable both with higher ISOs and long exposures. If you are not familiar with what stops are, each stop is double the previous value, so two stops are four times better. This is thanks to the new TruePic X image processing chip working in tandem with the Stacked BSI Live MOS Sensor.

The extra stop of dynamic range means the camera picks up shadow details that were not visible in the E-M1 Mark II's pictures

I tried both high ISOs and long exposures and was pleased by the improvements. With the advent of AI noise reduction, such as Topaz Denoise, DxO Deep Prime, and On1 NoNoise, clean, sharp images should be achievable at high ISOs, once the various processing and editing programs are updated to handle the camera's raw files. Be sure to also download the free AI Noise Reduction software for the OM Workspace software, but only if your graphics card has more than the 4 GB of VRAM minimum requirement.

I carried out a quick test of the ISOs, and these are the results, without Noise reduction.

Some random objects placed together for their colors, lit solely from a north-facing window. The reproduced colors were a  match for the original objects. Shot at the native ISO 200.

The same image cropped to 100%

ISO 400

ISO 800

ISO 1600 still produces a clean and usable image. There are a few artifacts visible in the greens, if you look closely, but nothing that isn't easily recoverable in processing.This was close to the limit I was happy with on the OM-D E-M1 Mark II

At ISO 6400, luminance noise is a bit more apparent, especially in the greens. This is still acceptable and nothing noise reduction software, or zooming out, would not remove. There is still plenty of detail and no appreciable loss of colors. 

At ISO 12800, the luminance noise is more apparent at 100% crop. But it's still at a level that would be easily fixed by an AI based noise reduction program. There is no chroma (color) noise visible. I can see a slight loss of details in the yellow flowers.

At ISO 32000 and above there is appreciable luminance and some chroma noise. Again, I have removed worse noise than this using AI software, and it's performing far better than many cameras at this sensitivity. Furthermore, I have never needed to use an ISO that high.

The uncropped image at extended ISO 32,000. Still perfectly usable at this size, although significant noise is visible when pixel peeping.

Uncropped at ISO 40000. There is still plenty of detail, although noise is visible. The camera goes up to ISO 102400. I look forward to the noise reduction software being updated to try it on these high ISO images.

The In-Built ND Filter Opens and other Computational Techniques

The computational photography facilities of Olympus cameras were always a hidden gem that their camera owners loved. Unlike the old Olympus, OM Digital Solutions are rightly highlighting these features, some of which are unique to the brand.

The image below was a handheld 3-second shot combining the inbuilt ND64 with my URTH ND1000 screw-on filter. To the right is an approximately 200% enlargement showing the sharp detail of the island that is just over a mile distant. No exposure compensation was added, and although shooting contre jour, details can be seen in the shadows.

This next image was again a handheld 1-second exposure with a 15mm focal length

Previously, on a bright day, I would struggle to get a one-second exposure using just the ND1000. Combining the two, I can extend that to up to a minute-long exposure. That’s something I could only achieve before by stacking filters.

3.2 second exposure combining the inbuilt ND 64 filter and a screw-on Urth ND1000



The following was a 17-second exposure, using Live Time. That allows me to watch the image gradually develop on the rear screen. Again, the noise control was superb. This was shot before sunrise with the ND 1000 filter fitted.

As yet, I haven’t tried light painting with the camera using Live Composite mode. I would be embarrassed putting my results out there when Hannu Huhtamo is out there creating astounding art. This amazing feature, unique to OM System cameras, shoots a frame and then only adds new light to the shot, allowing Hannu to create these marvelous compositions.

Video and Other Features Worth a Mention

Video would need a whole new review of its own, so I am just going to brush over it here. Historically, Olympus stood back with its video specs, leaving that to Panasonic to rule the roost in the Micro Four Thirds field. But there has now been a huge leap forward with the OM-1. Especially so with its 4K/60p with 10-bit 4:2:2 color depth, and the 120 fps at 1080 – enabling slow motion shooting – capabilities, and its raw output.

I wonder whether OM Digital Systems will start producing dedicated video lenses without graduated f-stops.

The dust cleaning system is as good as ever. I have never had to clean dust from any of my previous Olympus cameras.

The camera also has HDR modes, combining multiple exposures into a single raw file; in-camera focus stacking compatible with pro lenses; a high-resolution mode, creating up to 80-megapixel images using sensor shift technology, including a hand-held version; plus a multiple exposure mode where you can see the image you want to overlay within the viewfinder before you shoot the second image. There’s also “Starry Sky AF” that ensures the night sky is sharply focussed.

Finally, the color reproduction seems to be spot on. I matched test shots against the original items, and they seemed identical using the “Natural" picture mode. 

Will this Camera be a Success?

This camera lives up to the exacting standards of the first camera to bear the OM-1 name half a century ago. But, will it be as successful, and what does this all mean for the future of the OM System?

Now OM Digital Solutions is not shackled to developing technologies that must also be of use to the medical industry, it appears to be concentrating on doing what, historically, it did best: making innovative first-class cameras that meet the needs of photographers. Their ongoing pushing of the boundaries of what a camera can do has to be good for the industry as a whole.

In many countries, OM Digital Solutions have been taken aback by the initial demand. The huge numbers of pre-orders mean the OM1 sold out their first two months of stock before it hit the shelves. Several suppliers are on back-order, so those buying now will have a short wait before their camera arrives, but OMDS are increasing the supply to meet the shortfall. This is a different situation from the recent delays with the Olympus 150-400 pro lens where production could not keep up with demand.

I contacted Mark Thakara, Content & Community Senior Manager at OMDS about this.

We have been quietly confident for some time that this model would do well. We planned accordingly and substantial stocks have arrived on time around the world ready for initial shipments. Reaction and order intake for the OM-1 have more than exceeded our forecasts. We are excited about the growing enthusiasm and high interest in the OM SYSTEM brand and we would like to manage expectations a little. Our successful pre-order promotion does mean not everyone will get their OM-1 right at the start but more will be on the way on a regular basis from now on. Therefore, we recommend customers contact their local retailer to confirm availability. We appreciate the understanding and can assure everyone that this camera is worth any possible wait.

What I Liked About This Camera?

I make my living from photography, but only because I enjoy it so much; if I didn't, I would do something else. I need photography to be pleasurable, and this camera is a delight to use. There are plenty of reasons why I am pleased with it:

Firstly, I enjoy learning, and there is a lot to learn with the OM-1.

Next, there is a big leap forward in image quality; the increased dynamic range and operating speeds are noticeable in the real world, thanks to that new sensor and powerful processor that enable all the unique features mentioned above.

Third, I am glad that OMDS chose to listen to the Micro Four Thirds users and make improvements where they were needed, and not chase more megapixels, as dictated by the big brand marketing departments. I don’t need bigger files.

Then there is the menu improvement. That will make it much more accessible for new users. It’s color-coded and the sub-menu names are better. Although a different layout from its predecessors – I liked the previous version – it is still familiar enough to not seem completely alien. Furthermore, the four custom modes, and the customizable “My Menu” mean that delving into the depths of the menu system is usually unnecessary. What is more, if something is grayed out, with the press of the "Ok" button, a dialog box can tell you why.

Fifth, I find the camera comfortable to use, and the buttons easy to reach, and its name is much less of a mouthful than its predecessors. It also feels really well made too. Plus that new EVF is crystal clear.

Sixth, the computational photography features are useful in the real world, and not gimmicks like fake bokeh. This is a serious photographer's camera.

What Could Be Improved

There is only one area of improvement that struck me: I wish the removable-battery charger had been included in the box. The USB-C charger and in-body charging are great, but I prefer to have my camera safely stored while I charge batteries. I also try to avoid long-term use of sockets and body covers to prevent wear. Plus, in some circumstances, I want to charge one battery while I am using the other. Consequently, the additional battery charger is on my shopping list. But that’s a tiny gripe; I know photographers who are happy with in-body charging.

A useful review. I just jumped into Olympus late last year (M1x and M1///). I'm curious about real-world use of the OM-1 versus these, as I don't want to spend for a modest improvement.

Chris Boyd's picture

If you do landscapes or other static subjects, I would not bother upgrading. I went from the M1-iii to this for the new AF system. Weather has been bad but so far in limited use I am happy I upgraded. Missed too many shots with the M1-iii when the wildlife moved and or was moving. Easy to setup the subject tracking on a button and easy to change subjects. It sticks to animals and birds pretty well.

That's very kind, Alex. Thank you.

Andy Day's picture

I agree with Alex.

Ivor Rackham's picture

Ha ha. That's my self-esteem boosted for today.

My two problems with the OM-1: mine hasn't arrived yet, and Watson doesn't have a universal charging plate yet for the new battery.

Ivor Rackham's picture

It takes time for third-party manufacturers to come up with new accessories. You'll be pleased with the camera when it does arrive.

Jan Steinman's picture

Thanks for informing us about the Watson multi-battery charger!

Alas, I fear it may not be long for this world. I could not find a retailer who stocked it, so I bought a used one on evilBay. And the second "red flag" is that B&H is closing out Watson adapter plates for $1.99, when their retail was $9.99 before.

So I'm hopeful that a BLX plate will be coming, but it appears one could modify a BLH plate to fit: https://www.dpreview.com/forums/post/66029135

I just ordered a Kastar wall-plug battery charger for the BLX-1 battery from Amazon. They also make two double battery chargers, but these aren't wall chargers. I have never used this brand before, but they do make a lot of chargers and batteries according to their Amazon store. I won't get this for a week or so,but thought the community should know it's available. It's only $9.95. I'm keeping my fingers crossed that it will work OK. My default charger is the Watson DuoCharger; I assume Watson will be coming out with a plate. Note: I'm not sure B&H is closing out Watson battery plates just because the price is $1.99; thier chat service is currently closed, so I couldn't ask them. Beside, Watson products are available all over the place.
It certainly is chintzy of OMDS to not include an external charger; and they certainly know what I think about it.

Maybe I'm paranoid, but batteries are most likely to fail (leak, outgas or fire) while charging. I'd much rather that happen OUTSIDE the camera.

Ivor Rackham's picture

The battery technology has come a long way and the risk of that happening has fallen a long, long way over the last decade. After all, all phones are charged with the battery inside.

Saying that, I bought a charger, extra batteries, and a power bank so I could be on a whole day or multi day shoot with no worries. Plus, I like to keep my cameras safely stored in their cupboard and not have them using space on my desk on charge. But, I know others who charge in camera with no qualms.

Personally, I do wish the OMDS had waited a generation of camera with this battery before excluding the charger from the box, but that would have pushed the price up for everyone, even those who didn't want the separate charger.

J Barber's picture

I agree with your approach (admittedly the fire risk is small, but has happened with phones) . Like you I keep multiple camera batteries charged and ready (just like my shelf of power tool batteries).

I bought an external charger and batteries for my wife's camera as well. Encouraging her to get in the habit.

Paul Stephenson's picture

A lovely simple review concentrating on what really matters to a photographer, nothing more needs saying. I've been using Olympus from the OM1/OM4ti era and always loved their innovation. I'm invested in the M4/3 system which is just as innovative. New OM1 arrived yesterday and I can say I'm just as excited about it as I was my original. Like you the old menu didn't bother me but I think when I get my head around the new one it will be simpler. Unlike you I've not got out taking images with it, planned to do it today but tested positive for covid (caught of my wife who's had it for 6 days)!

There are no camera brands producing bad cameras today, all that is important is finding one that suits your needs and feels right in the hand and becomes part of you. ...and yes agree about the battery charger.

Thanks for the great review.

Ivor Rackham's picture

Thank you for that kind comment. I hope you recover quickly and feel okay while you have that horrible infection.

sam w's picture

my EM5ii is still in very good condition, but looking at this camera, it's starting to feel a bit ready to be upgraded.

Ivor Rackham's picture

The E-M5 ii was one of my most favourite cameras I've ever owned. For day-to-day shooting, especially street photography, it was fabulous. I still miss mine. Performance wise though, the OM-1 leaves it standing.

Dave Rausa's picture

Coming up from an EM5-ii and a G9, I have received my OM-1 and the difference in handling, performance, speed and available computational features has nearly made me forget how much money this thing costs. I believe OM Systems have offered a very competitive camera for those who know what they are after. Those hungrier for more and more megapixels will obviously look elsewhere. For the camera the OM-1 is trying to be, its the best I have ever held. Nice write up Ivor - very practical look at what this can offer.

Ivor Rackham's picture

Thank you David. I hope you enjoy using it.

M Hector's picture

Great review! Thank you. I really like this camera. Your photos are impressive, and the associated real-world situations and conditions really help me to understand how the camera performs in our hands as opposed to in a lab or tightly controlled conditions.
I will have to rent one of these to further lure me towards buying one! I just bought a camera body about a year ago, though.

Ivor Rackham's picture

Thank you!

(That's what MPB is for!) Is the OM Test and Wow operating near you? You can borrow one to give it a go. If you do, then read up on the settings first, or book a one-to-one with one of the OMDS guys for a free tutorial, especially if you haven't used Olympus cameras in the past.

Eric Robinson's picture

If I were to do it all again. Choose a camera brand. This would be the way I would go. The features on this system makes it very desirable especially for wildlife. Great review.

Ivor Rackham's picture

Thank you Eric

Michael Krueger's picture

Those handheld long exposures are impressive, I really need to get myself an Olympus camera one of these days. I've got some Panasonic gear so I'm already invested in M4/3 but haven't gotten a camera since 2019 due to the pandemic destroying any profits I made.

Ivor Rackham's picture

Yes, the last couple of years have not been easy for us photographers.
