Om system om 5 vs om system om 5 mark ii?

The two bodies share the same 20.4-megapixel Micro Four Thirds sensor, the same in-body stabilisation, and the same small size, and they take the same lenses. The main difference is age. The OM-5 came out in 2022 and I still call it a hiking camera. The OM-5 Mark II was announced in 2025, and its page specifically mentions IP53 weather sealing. If you're buying new, I'd go for the Mark II. If you find a good deal on the original, it will still do the job.

For a hiking kit, I'd pair either body with the Olympus M.Zuiko 12-100mm f/4 IS PRO for one lens that covers most of a day's shooting. For something lighter, the Panasonic Leica DG 12-35mm f/2.8 is a good compact standard zoom.
