Mark, Interesting! I'm quite familiar with the Pentax 67 system, having used much of it years ago, including some of their long lenses. Of course that was with film and the image related issues that might crop up with their use while interfacing with a digital sensor, I can't say. Some of their glass although good, wasn't ED/APO (depends on the lens) and even those (the non ED glass) would give up something to the more exotic glass of that time or even today. So a lens by lens trial on the S2 is possibly the only way to know. The Pentax ED long lenses were supposedly exceptional in their performance.Dave, I have been wanting to try a long lens on my S2 for a long time. I have kept my Canon system with 500mm because I don't want to give up the long telephoto. Now that adapters are available for the S2 there are several options for longish telephoto. Al Tanabe is loaning me his Hasselblad 350mm CF to try when I'm down in South Florida in a couple weeks. I have been looking around at both Hasselblad and Pentax 67 telephotos and there's seveal options all the way up to the Pentax 800mm beast. My biggest problem is that I don't have history or knowledge of older manual focus / manual aperture MF lenses. Al has been trying to teach me what to look for.
I hadn't even considered the Pentax 67 glass on the S2 when I posed my question, since I didn't think there was a S2 adapter for Pentax 67.
I assume (haven't looked at the dimensions), that Penatx 645 glass is out of the question, due to image circle issues when used on the S2?? Reason being is there was some good long glass for Penatx 645, especially their high end 400mm ED glass. Again the Pentax 645 system comprised of older non ED long lenses (originating from the Takumar series) as well as some modern, more recent ED long lenses.
I've heard some good things about the Hassy 350mm CF but thats all I know about it.
Kurt, couldn't agree more since there are so many good R series glass to choose from. In addition (and on a seperate note) I'm surprised the R system was dropped, rather than updated.
