Range Finder

One modification available on the Deluxe and Premium Models is the choice of viewfinder. At the time of purchase you may choose which viewfinder your camera comes with. Most will want one of the metal Zeiss-Ikon manufactured Range Finders, though all three styles are available.

All view ports work well, though it has been noticed that the smaller windowed Zeiss version seems to have more range finder overlay to it. The differences between the two Zeiss rangefinders is ONLY in the outside metal cover, internally they are identical.
