Released in 2022, the OM-5 targets travel and outdoor photographers specifically, built genuinely lighter and smaller than the flagship OM-1 while retaining serious weather sealing rated for harsh outdoor conditions — a combination the Micro Four Thirds format's smaller components make considerably easier to achieve than on larger sensor formats.

The OM-5 also inherits Olympus's Live Composite mode for real-time star-trail and light-trail blending, a genuinely distinctive long-exposure feature that previews a multi-minute exposure as it builds rather than waiting until the shutter finally closes. Its IP53 dust and water-resistance rating is independently tested and verified, a genuinely rigorous standard rather than a vague marketing claim of weather resistance. A genuinely rigorous standard.
OM System also gave the OM-5 a genuinely capable 50-megapixel handheld high-resolution shooting mode, combining multiple frames into a composite well beyond its native 20.4-megapixel output for static subjects. A genuinely useful computational feature.

Frequently Asked Questions
Is the OM-5 built for serious outdoor conditions despite its smaller size?
Yes — the OM-5 carries genuine IP53-rated weather sealing against dust and light rain, a real practical advantage for hiking and travel photography, and its Micro Four Thirds sensor lets OM System achieve that sealing in a considerably smaller and lighter body than most weather-sealed larger-sensor cameras manage.
