Reviewer Consensus

Strong

The OM System OM-3 is a compact, retro-styled camera that integrates flagship-level computational photography and weather-sealed durability into a portable, metal-bodied design. While it offers a premium, highly tactile shooting experience, its high price point and lack of a dedicated grip or advanced viewfinder resolution may be limiting for some users.

What the Reviewers Say

  • PetaPixel 7.5/10

    The OM-3 is a beautiful camera that packs a ton of high-end features. It does have some concessions compared to the OM-1 Mark II, but they're fairly minor and aren't areas where those interested in this vintage-styled camera will likely be particularly bothered.

    If you can live with the Micro Four Thirds sensor that's smaller than full-frame, but which enables a truly compact and lightweight camera / lens system, then the OM-3 should be right at the top of your shopping list.

  • The OM-3 camera’s price relative to its sensor size is on the high side, however it has a couple of important factors in its favour that could make some potential buyers choose it over alternative full-frame and APS-C cameras.

  • The OM System OM-3 combines popular features of the PEN-F and OM-1 II in a smaller, lighter form factor than the OM-1 II but with the same IP53-rated weather resistance.

    So while the OM-3 is a beautiful camera with excellent performance, solid build and undoubtedly can produce very nice images: it just seems to really miss the mark with regards to design choices and price point.

    While there are a few gripes with the OM-3, for the most part it's a fantastic camera, and one of the best M4/3 cameras out there.

    Despite some of the complaints I have on this OM-3 camera, I don't think any of them are deal breakers. I still think that this OM-3 is a fantastic street photography camera, of course, if the price tag $2,000 does not bother you.
