10mm Metal Optical Viewfinder (Black)
The black 10mm Metal Optical Viewfinder from Voigtlander is a shoe-mounted finder that can be used to provide an approximate field of view for lenses with a 10mm focal length. Designed for use with a 35mm film or full-frame digital camera, the finder slips into the camera's accessory shoe and allows for accurate photo composition. It offers an eye-level 0.32x-magnification viewfinder with a reverse Galileo Albada design, and brightlines that represent the field of view when focused at infinity. It uses five elements and has a -0.6 diopter for comfortable viewing.
