SF-1

I have a pentax SF-1 auto-focus camera with a Takumar telephoto lens. Does anyone know if this type of auto fucos telephoto lens would be compatible with say the petax digital cameras, like the K100D?

Thank you

The Tak is auto focus? If so it is fully compatable with all the DSLR's from the *ist D through to the K10D.

The SF-1 is a k-mount camera and as such, the lenses that fit it, will fit the new DSLR's. Including auto-focus lenses. Nearly all Pentax lenses will fit the new DSLR's, some need an adapter. There are a few out there that are k mount and do not fit at all however. They would be early k mount lenses that were designed for manual-focus k mount cameras. These have an elongated shutter guide that interferes with the AF mechanism inside modern auto-focus capable k mount cameras preventing the lens from even being mounted. Some of these lenses can be adapted to fit with the removal of the shutter guide. Usually 3 small screws holding the guide in, remove the screws and the entire guide and the lenses work fine.

Thanks for your replies. You have been all very helpful and saved me a decision that I may have later regretted. Thank you
