Sony E body + Mamiya 645/Phase One lens


You can mount a medium format on NEX, but there are some issues with it.

Medium format systems differ in many aspects from the usual 35 mm ones. Multipliers, focal points, sensor/tape sizes are all different (actually, medium format means anything larger than 35 mm but smaller than large format, therefore "medium format" doesn't describe an exactly defined size).

Medium format lenses can be mounted on E bayonet locks The FotodioX adapter usually costs $ 50-60. You'll have to keep in mind that because the fullframe or the smaller APS-C sensors are significantly smaller than the medium format ones, therefore the center of the picture will be cropped (due to the focal length multiplier).

Kipon announced an E-mount adapter with "lens turbo" function, which has some additional lens components shrinking the medium format image to fit the fullframe sensor. A real professional solution.

In terms of compatibility, we distinguish four separate categories:

This means that you'll be able to apply the lens on the camera in question with a proper adapter, and full focus range will be available with it (often with aperture control too). If AF is supported, you'll see it in the description.
This means that due to the flange focal depth or other factor this conversion would be normally unfeasible, but with some compromises (e.g. using a speedbooster adapter) can be made possible.
This means that the flange focal depth should make mounting and using inifinty focus possible, but for some reason there are no adapter rings available or other factors make it unviable.
This means that you won't be able to mount your lens due to mechanical incompatibility or the difference in flange focal depth doesn't make inifinity focus possible. Although numerous lenses can be mounted on cameras without infinity focus, but this cannot be considered actual compatibility.

Additional information for compatible variations:

manual focus (on the lens, with its own control ring)
autofocus available (AF controlled by the camera body)
manual aperture control (on the lens, with its own control ring)
automatic aperture control (controlled by the camera body)
speedbooster (focal reducer) adapters are available
macro (variable length) adapters are available
tilt-shift (or other flexible) adapters can be used

If you'd like to read more in-depth about compatiblity, you'll need to get familiar with flange focal depth, see this article.
