The FotodioX Sony A Pro Lens Adapter with Built-In Iris for C-Mount Cameras is a high quality adapter that allows you to mount a Sony A mount lens to a C-mount camera body. It features a brass construction with a stainless steel finish as well as the ability to focus to infinity. This works with a leaf spring system for a secure attachment of the lens to the adapter. Additionally, this adapter features a built-in iris for determining the amount of light let into your camera.

Although the lens will fit physically, automatic lens control and functions will not operate correctly while using this adapter. You can utilize aperture priority mode in combination with stop-down metering for automatic exposure control on your camera.

Q: 1. Will this adapter fit a Zeiss Jena Flektogon 35/2.4 in M42 mount to a Leica M3?

A: WE cannot test that lens specifically but the FotodioX M42 Pro Lens Adapter with Built-In Iris Control for Leica M-Mount Cameras will adapt most M42 mount lenses to a Leica M mount camera.

Q: 2. What frame lines will it show for leica film cameras?

A: It will not bring up any frame lines but the Leica film cameras have a manual lever so you can set the frame lines. The frame lines can be changed with the lever that's on the front of almost all Leica cameras, the little frameline selector level, It will change what you see in the viewfinder. The Leica M2, for example, has 35mm, 50mm, and 90mm frame lines inside. So if you are adapting an 85mm lens, you would probably want to use the 90mm frame lines so get a close estimate.

Q: 7. Adapter will not release from the 100-400 Canon EF lens. I cannot find a release mechanism anywhere. Any solutions?

A: Hi Thomas, Sorry to take so long to get back to you. It is very simple to release the Canon/ Fuji adapter. Just slide the little button toward the blue ring. Twist as normal and that's it. Good Luck! I use mine on the Rokinon 8mm fish-eye (B&H) on my Fuji and it is great!

Q: 8. I just received Fuji X-Pro2 with Fotodiox yesterday. I mounted the Fotodiox and then a 50mm lens. I was able to manually focus (focus peaking works well), but I can't get the shutter to fire--I press the shutter button but nothing happens. Is there a setting in the camera that I need to change? Or is it the Fotodiox?

A: With my X-T1 it works when the menu item for soot without lens is set to yes. I would think that the X-Pros has a similar item in the menu. It is necessary as there is no electronic connection to the camera so it does not know that there is a lens attached.

Q: 9. I want to use this adapter with my XT-2 and Carl Zeiss (ZE) lenses, so I'm ok focusing manually, and I think the built-in iris control should help with the lack of an aperture ring on the lenses, but what kind of disadvantages should I expect by using these three (camera, adapter, lenses) together?

A: the aperture doesn't work - dont bother

Q: 10. What frame lines does this adapter bring up on a M 262?

A: This adapter would not bring up any frame lines with the M 262.
