I have a large collection of Exakta cameras and a few more lenses than I need so I wanted to try some on my digital bodies. I bought a Fotodiox Pro Exa-PK adapter. This is one with a lens in it to allow for infinity focus. Problem 1...A number of lenses, usually wide angle, extend back past the edge of the lens mount hitting the adapters lens, making infinity unreachable. Problem 2...in spite I'd having a coated (appears to be) lens in it, it exhibits terrible flare. I have an example attached.
1) K70 with adapter and Steinheil 55/1.9
2) Fotodiox adapter
3) 3502 image taken using Steinheil without adapter (holding it in place with my hand)
4) 3501 image with Steinheil and adapter
5) 3496 Image taken with HD Pentax 35/2.8 macro
The image I took holding the Steinheil up to the camera with my hand is better than with the adapter. The adapter is really only usable with some lenses in low contrast shots...for the most part it's crap and I wouldn't recommend anyone using it.
Shots are ISO 1600, apertures f/5.6 or 8...
