Can i use Nikon lens on the Olympus PEN E-P1?
Yes. The lack of a mirror box in Panasonic’s and Olympus’ Micro Four Thirds system allows for a shorter flange focal distance than the traditional SLR design. The FFD of the PEN E-P1 is shorter than that of Nikon’s—which happens to use one of the longer flange focal distances—so you will be able to use most Nikon F-mount lenses with few exceptions. In fact, the M4/3 FFD is so short that it’s the most adaptable digital interchangeable system currently available. All you need is a Nikon to Micro Four Thirds adapter of which there are several to choose from. If you want an “official” adapter, Voigtlander’s Nikon F adapter is it: http://www.cameraquest.com/adp_micro_43.… There are plenty of other “unofficial” adapters available too that may work just as well:
