Nikon Series E 50mm f1.8 lens mount_Mamiya NC Works on most EF cameras

Works on most EF cameras and many EF lenses

It won't hold the Contarex

Shoots up to 72 vertical half frame images on a roll of 36 exposure film- definitely an economical proposition

but you'll need to use the included external viewfinder to frame your shot (it's too wide for the camera viewfinder)
