OM System

If you’re a wildlife or nature photographer, you’re probably looking for a rugged, lightweight and highly-durable camera that also delivers high-quality photography and videography. For that, look no further than OM System cameras, and you can find a wide range of cameras, lenses and accessories at Castle Cameras.

You’re not likely to find a tougher camera around than the Tough TG-7 Digital Camera, which is compact, lightweight and extremely durable. It can also shoot underwater to a depth of 15 metres and features a F2.0 high-speed 4x zoom lens for sharper images. The OM-1 Mark II is the most popular OM System camera, the OM-3 is perfect for creative photography and the OM-5 is built for adventure.

In addition to the many cameras you can find, there’s also a broad range of OM System lenses too, ensuring you can capture high-quality photos and videos no matter what you're shooting, what the weather conditions are, and how far away the object is. Some of the most popular lenses are from the M.Zuiko Digital ED line, including the 90mm f3.5 Macro IS PRO, and 150-400mm f4.5 PRO lens with TC1.25x.
