Two years after the unveiling of the Olympus OM-1 ($1999), OM Systems announced their next flagship: the Olympus OM-1 MKII ($2,397). It’s a 20 MP (5184 x 3888) camera with a stacked BSI Live MOS sensor and TruePic X processor. Hey, just like the OM-1 mark 1. As you probably guessed, the new camera does not change much over the original OM-1, but it is more of an incremental improvement of the body and the software.

If you look from a high vantage point, the biggest improvements are enhanced AI subject detection for humans, live graduated neutral density filters, updated menu configuration, 14-bit raw output, and rubberized dials. I’ll touch on all of them.

The Om-1 MKII is impressively rugged

Except maybe the Nikon Z9 units that NASA modified (and maybe some single-digit old Pentax K cameras), the OM-1 MKII may be the best mirrorless around for harsh environments. It boasts an impressive IP53 weather sealing and a freezing-proof design. In addition to its durability, the OM-1 MKII has incredibly high shooting speed with up to 120 FPS of continuous shooting (RAW, fixed-fixed point focus). Both durability and speed are great for shooting in extreme situations like photographing wildlife in the snow or fast rally cars racing through the dirt. (If you don’t trust me, see what this strobe looks like after a few days on the track).

In addition to the high burst speed, you can also use the OM-1 MKII pro capture mode. In this mode, the camera will take pictures for you before you press the shutter button. The camera can store up to 70 frames before you press the shutter to ensure you capture the right moment.

Graduated live ND

You may already know that some OM system cameras allow you to digitally mimic ND filters with the live ND feature. That feature has improved with the MKII, and it now also includes the option to mimic graduated ND filters instead of a “constant” ND filter. Effectively, this addition lets you darken one side of the image, which is particularly useful when you need to darken the sky.

The OM1 MKII gets improved autofocus

The Mark two gets an improved AI autofocusing system with multiple subject detection modes:

• Humans
• Birds
• Dogs
• Cats
• Cars
• Motorcycles
• Airplanes
• Helicopters
• Trains

The new modes should allow for a more consistent experience during your work. Olympus claims that the autofocusing capabilities improved even outside the subject detection modes, but it will take some time until we know just how much the autofocus has improved.

What’s new on the video side of the OM1 MKII?

I’m sad to say it, but the OM1 MKII hardly has anything new added to its video capabilities. There are no higher resolution or frame rate options. However, there is one small new feature available, and it is support for vertical video tagging.

Price and availability

As most of the improvements are not image-related, you could argue the new OM-1 MKII isn’t much of a successor camera to the OM-1. Instead, you could see the MKII as an updated version of the OM system’s flagship (maybe you could even see it as the OM-1 2024 edition). One way or another, the OM-1 MKII is a fitting and capable camera for anyone looking for a small and light but rugged machine. The camera will be available in February, but you can preorder one now for $2,397.
