Olympus pen e p7 vs om system om 1?
The OM System OM-1 is the bigger, more serious camera. It's a 2022 flagship with a 20.4-megapixel stacked sensor and a weather-sealed body. The Olympus PEN E-P7 is a small 2021 rangefinder-style camera with 20.3 megapixels, no viewfinder, and a switch for colour and monochrome profiles. Both use Micro Four Thirds, so they take the same lenses. If you want a light, stylish everyday camera, go with the E-P7. If you shoot in rough conditions or want a flagship body, get the OM-1.
Either way, a good starting lens is the Olympus M.Zuiko 25mm f/1.8 for a natural, portrait-friendly view. For a small all-round kit, try the Panasonic Lumix G 14-42mm f/3.5-5.6 II. If you want one zoom for the OM-1, the Olympus M.Zuiko 12-45mm f/4 PRO is a solid pick.
