Do you mean that old Pentax lenses can be used with the 645D camera by way of an adaptor?

Pentax 645 film camera lenses can be used on the 645D. But also Pentax 67 lenses can be used via the 67-to-645 lens mount adapter.

Older medium format Pentax 645 lenses do not require an adapter. To get auto-focus you would need to use a Pentax 645 FA lens. You can also use Pentax 6x7 lenses with an adaptor but they will be manual only and will not communicate with the camera. The lenses made for the Pentax 35mm cameras will not work with the medium format 645D as they are much smaller so no adaptor...

Tsundo, you can use them, but there are varied reports of how well they perform. See this discussion in the Pentax forums:http://www.pentaxforums.com/forums/pentax-medium-format-645-6x7-645d/127803-manual-focus-lenses-645d.html

Any 645 mount lenses will work on the 645D without an adapter, as well as 67/6x7 lenses with an adaptor. Many are excellent, some are average. Search around for some reviews of film and digital era lenses.

Yes. Check Pentax web site: http://www.ricoh-imaging.co.jp/english/products/k-5-2/accessories/

Yes, but you will need an adapter (sold by Pentax) to convert the screw on lenses to the bayonet type. The older bayonet types work fine. When using the screw on lenses (with the adapter), you must use manual mode on the camera (no automatic focusing or aperature control).

I have a Cannon EOS1100D and a Pentax Mount 750mm telephoto lens (I think, I have had it for so long that I don't remember the details). The adapter works with no issues when both the lens and camera are hand held. When the lens is mounted on a tripod, fitting the camera is a bit more difficult but not impossible. This is mainly due to lack of practice.

Yes! there are many adaptors available to attach all kinds of lenses to this camera.

If the old lenses as Pentak K-mount lenses; but check with the experts on Pentax Forums (which has FAQs about this).

Yes.. If you buy a lens with a PK mount it will work on any Pentax camera that uses the PK system. This includes all Pentax cameras going back to the start of the PK system (1980s?). Some features of newer lenses will not work with older cameras that don't support the new features, but the lens will still work in manual or non-auto-focus mode with older film cameras. All Pentax digital DLSR cameras that use the PK mount support the features of the new PK lenses. The Pentax Q cameras do not use the PK mount, but you can buy a Q to PK adapter (not the best set up, but it will let you use your PK lens on a Q system camera). Yes..

The good news is, any Pentax lens will mount on a Pentax DSLR (Hats off to Pentax). Even if you have an old screw mount lens, the screw mount to Pentax K adapter will work. Functionality is limited to the type of lens. If it's a manual type, you can use aperture priority mode on the DSLR and the camera will choose the sutter speed, like your ME Super can. I have a collection of Pentax lenses and bought a Pentax DSLR because I can use them on it. I use the standard screw mount 50mm that came with my old Spotmatic because the glass is super on it.

No! You can buy adapters for practically any lens ever made. You will have to focus manually, but the focus assist is very helpful. However, the Fuji lenses are FANTASTIC!!!

Old Pentax lenses are interchangeable with digital SLR's. God bless Pentax for that.

As long as your lens do not protrude beyond the inner lip. This adapter is designed to push the aperture pin on Pentax older lenses. As long as the threads on the lens is flush with the last lens segment there should be no problem I would think. You will have to make that evaluation yourself and for your needs. Good luck.

I would think yes. I used it in my 5 year old Pentax and there were no issues. I would get on the internet and see the storage specs for your camera. Speed transfer is important for older cameras which determines compatibility. Hope this helps.

Yes, but to make the lens changes quicker, you may wish to purchase an adaptor for each lens. It just makes life easier.

Hello Jenny J - yes you need a Pentax screw M42 to Cannon adaptor and you will have to use the lens with manual aperture settings - this vintage lens is from the late 60,s and provides excellent image quality - Cannon also made a 50mm F 1.4 at that period and it is also a very good lens to have

Well.... Guesing that you are looking for and M42 to K adapter for pentax, you can search here at amazon or outside, there are many. And the K5 is capable to use an M42 lens with the right adapter.

I am not sure, but I remember someone telling me that Pentax lenses are made to fit all Pentax bodies.

Yes, Pentax lenses are famous for their interchangeability. I use one of these daily for getting up close with nature, you know bugs and rocks and stuff.
