That’s to say that it’s good but not fantastic. Overall, combined with the OM1, it feels a bit like the Nikon z9 before firmware updates. If you’re using the simulated OVF function, you’ll get the best autofocus performance in terms of accuracy, speed, and all.

But there were surely times where the OM System 12-40mm f2.8 Pro II frustrated me over a period of a few months of testing.įurther, the OM System 12-40mm f2.8 Pro II struggles more with exposure preview settings activated. If it were a much longer focal length and photographing birds, it would be different. This is in some ways an antiquated way of thinking for a lens like this. So with all this said, you’ll have to give the OM System 12-40mm f2.8 Pro II a bit of focusing assistance by choosing an area for it to focus on. This is regardless of whether or not the scene detection is on. Can it be done? Sure! Is it as good as Canon or Sony? Nope! Canon and Sony tend to look at the center and the areas where the rule of thirds tend to intersect. Where Canon and Sony can focus on a scene and then immediately pick a subject out, OM System still lags behind a bit. Specifically, we’re talking about wide-area autofocus algorithms. Overall, we all agree that neither are just that intelligent compared to Canon and Sony. We’ve discussed the autofocus of OM System and Panasonic alike here in the staff. I tested this lens with the OM System OM1 and a bit with the Olympus EM1 Mk III.

Providing they don’t accidentally bump the focusing ring into the manual position, this lens will be easily used by any photographer out there. Otherwise, it’s a point, focus, and photograph affair. The OM System 12-40mm f2.8 Pro II shares the same pull-back mechanism for autofocus and manual focus switching as many other lenses. If you’re familiar with OM System optics, there isn’t anything out of the ordinary here. It’s a lens that you’ll want to bring with you everywhere you go. And I can’t really complain too much about that at all. It’s lightweight and feels awesome in your hand. Weather resistance aside, this lens is fantastic when it comes to build quality. Comparatively speaking, it doesn’t shine as much compared to many of the other PRO-monikered lenses from OM System. But in the grand scheme of things, there’s not a lot that’s groundbreaking here. It has better optics, fast autofocus, and a whole lot of things the previous version had. The OM System 12-40mm f2.8 Pro II doesn’t contain a whole lot of innovation over the previous lens.
This has the depth of field of an f5.6 lens on full-frame cameras when being used wide-open.
At the longer end, it delivers nice bokeh.You can purchase this lens from Amazon, Adorama, and LensRentals Keeper Program. We’re awarding the OM System 12-40mm f2.8 Pro II four out of five stars.
