Right now I have Pentax ME Super SLR camera and I want to buy some telephoto lens. Additionally, I plan to buy medium-format camera in some (near) future. In consequence I wonder: Is it reasonable to buy right now the medium-format lens and use it with full frame SLR, so I will already have right lens for future camera? I would also like to find the cons (and pros) of such a configuration, especially:
- Can the greater field of view be a source of some internal reflections in the camera body?
- How does the focus range change with such a mount (especially ability to focus at infinity)? Are the lens adapters designed in such a way that this focus range can remain unchanged?
- Does greater field imply that the 35mm image is less prone to lens aberrations?
- Apart from stop down metering, is there any other shortcoming of such a mounting?
