    The new OM-5 Mark II from OM System (formerly Olympus) is a very modest upgrade of the three-year-old OM-5, which was itself a gentle evolution of 2019's EM-5 Mark III.

    The OM-5 II has been criticized for offering few improvements over its predecessor, but I think that’s missing the point. If a camera does a great job at a great price, why hike the specs and change everything?

    Now that I've revisited the OM System OM-5 Mark II, I do think particularly now that the prices have come down, it's well worth a look if you want an everyday carrier that is small, stylish, weather sealed, and has good AF.
