Has anyone here had experience using 67 or 645 medium format lenses on a Pentax k20d? If so, what are the results like and what kind of adapter (if any) is needed?

My apologies if this question has been addressed already, I didn't search the threads thoroughly.

Thanks.

IMHO it's rarely worth the effort. 6X7 lenses are all extremely bulky and slow. 645 lenses are smaller but still, none faster than F2.8. If you don't already have a collection of medium format lenses, it doesn't make much sense to buy them and then only to use a tiny fraction of the image circle.

The only medium format lense I might be interested in using on a K20D is the 645A 120mm macro. It's cheaper than its K-mount counter parts even after you factor in the cost of an adapter.

One of the most important thing my camera does is take pictures of my paintings. So a goal is to do as little photoshop work as possible and to get the best reproduction quality possible.
Would a medium format lens flatten out perspective better than lets say a 135mm takumar?

no because in the end it's the focal length that matters

Scott:

I shoot these lenses on my K20--please see this thread. There is much discussion, and samples too. Also, I provide a link to an adapter in there--somewhere.
