Manua Focus


I have what is probably a dumb question. Can I still get focus confirmation(beeping sound) when I use a manual focus lens on my DLSR?

There has never been a Pentax DSLR model without focus confirmation or in which focus confirmation stopped working just because you had a manual lens mounted.

Not to mention that every Pentax auto focus camera allows catch-in-focus, formerly snap-in-focus. Even with a manual lens installed, if the camera is in AF.S (single) the camera will not take an image until focus is detected. I use it occasionally even with my M 400, although the small aperture makes it less than optimal at dark times. I use it very often with my M 100 macro. Set the magnification on the barrel, hold the shutter release down, and sneak up on that bug.

As the others said, yes you can, but only the center AF point will give you focus confirmation, if you use a manual lens.

Please note that this will work only if your lens has a conductive mount plate.
If not, you'll either have to scratch its paint, or add some conductive material, so the camera's mount contacts are grounded.
Moreover, if you ground the A contact (the one slightly recessed), you'll enable P-TTL with those manual lenses, with some limitations (mainly with PK-M lenses, it works quite well with m42 lenses).
