Nikon D7200 lens mount_Olympus Pen The Nikon K-ring set isThe Nikon D7200 is a fast shooting 24mp DSLR with excellent low light performance, a dramatically larger buffer (vs the earlier D7100), WiFi and NFC functionality, and more. It shoots video in 1080P at up to 60fps with a slight crop, or up to 50fps without. In very condition, with minor cosmetic surface wear and under 1000 actuations. That's not a lot of actuations! It includes a battery, charger, strap, and instructions.
