I picked up an OM1 Mk 2 from Park Cameras this morning and here are my initial subjective impressions from using it with the Panasonic 100-400 and Oly 150-400 for a couple of hours.
I hope this helps prospective buyers and starts to build a more realistic view of the impact of the changes.
Best wishes, Peter
- Rubberised dials - These seem to have the same rotational stiffness as the Mk 1 but the rubberised coating gives your finger better grip so you don't have to apply so much force into the dial notches in order to turn the dials. I had hoped the dials would have a lower rotational stiffness as well, like those on the EM1X, but this is not the case. The click sound is just like the Mk1.
- Human AI autofocus - Seems more effective than the Mk1, and being able to select it from the AI subject menu makes the experience of changing modes clearer and easier. I need some time with my 2.5 year old granddaughter to find out whether the Mk 2 now does the job well!

- Bird AI Autofocus - The mk1 is already good but the Mk 2 seems more consistently accurate when the subject is clear of foreground objects. It also felt more effective when the bird was behind twigs, although it still sometimes chose to focus on foreground objects. The autofocus changes have made a good first impression and make it feel more sure footed, Hopefully specific improvements will become more apparent with use.
- Autofocus with Half-press and AF ON button - I liked being able to make one of these use AI subject detection while the other used the selected AF area. This enabled me to use subject detection on half-press and to switch instantly to AF area mode (I used single point) if the subject detection failed to lock on. It was very convenient that I was back in subject AI mode when I released the AF ON button i.e. that I didn't need to do anything to revert to subject detection.
- Drive Mode and AF Mode Buttons - These are slightly more proud on my Mk2 than on my Mk 1, making them somewhat easier to select. This may be a real change or could just be down to sample variation.
- CAF/TR - Feels a lot sticker. I found that the CAF/TR option is only visible when subject detection is disabled! I think this option should always be visible but should be greyed out when it can't be selected.
I hope this helps prospective buyers and starts to build a more realistic view of the impact of the changes.
Best wishes, Peter
