Pentax 6x7 lenses - can I use them on other bodies?

[Rob MacKillop]

I love my four Takumar lenses on my Pentax 6x7, and wondered if they could be used on a 35mm camera with an adapter, or other MF cameras with or without an adapter? I have the 75, 105, 200 and 300mm.

There is an adapter, made by Pentax to use them on Pentax 35mm bodies, I have one, I believe one was made to use 67 lenses on the Pentax 645 cameras.

Interesting. Thanks, Mark.

And here is the 67 to 645 converter

There are also ones for Fuji medium format and Nikon F mount cameras by 3rd parties.

Thanks, Mark. I'll get one in the UK. The Nikon F would be useful. I'll look for that.

FWIW... I got an adapter for P67 to Fuji-X digitals and was quit disappointed with the results. I've had hit/miss success with heritage lenses on my Fuji gear and some favorite film era optics have not worked as expected. Some moderate value glass has worked very well in that application so I've given up predicting success! My P67 to 645 experiences have all been good, though and that adds a lot of versatility to my glass accumulations.

Cheers, Craig.

Adapters for some lenses on some cameras do not permit infinity focus due to the flange to film distance. I have no idea if this is an issue for your P67 lenses, but worth verifying.

Thanks for the tip.

Pentax 6x7 or 67 lenses (all variants) usually work well on Pentax 645 bodies (film or digital). The Pentax 645 adapter retains open aperture metering and automatic aperture stop down during exposure and are usable in manual and aperture priority. AF P645 bodies also offer
focus confirmation in the viewfinder.

The 35mm Pentax K adapter requires stop down metering and manual aperture (using the auto/man switch on the lens). On 35mm or smaller formats, the lenses are a bit overkill as they're much bigger & heavier than native lenses and mostly slower as well.

The P6x7 has a flange distance of something around 80mm, meaning most adapters for most smaller formats should be able to get infinity focus.

Cheers, John. Lots of good info there. Much appreciated!
