This is a small optical viewfinder that attaches to the hot shoe of a DP1 model camera. It has a frame for 28mm equivalent (35mm film camera equivalent). There appears to be a crack in the lower right corner of the viewing side, but it's not visible when looking through it. The exterior is in particularly clean condition with no noticeable scratches. Optically, there are no scratches or dust particles, but please understand that this is a used item before purchasing. #Sigma #Sigma #Viewfinder
