OK, this is my first thread on this fine forum so be gentle with me (besides, my cat has very sharp teeth ....). I just ran a search on this subject and it was no more productive than my searches on other forums usually are - no surprises there! Said search picked up only my own post of this morning (made in the wrong subforum really ..), so here I am folks. My eyes still moist over a bit when I fondle my Asahi Super-Takumar 50 mm f/1.4 and Super-Tak 28 mm f/3.5 screw mount lenses that I got in the late 60's (Pentax Spotmatic body). But, I haven't actually made an exposure through one in at least 20 years. My.. how.. time.. flies! I won't bore you more with my intervening cameras (film SLR and digital P&S) - besides I already did that in another post - but I'm seriously in the DSLR market looking at the K10/D80/30D (to-be-announced 40D ..?) type of body. Hope I've got that all correct, I'm still a bit shaky with the nomenclature .... All very well BUT, a big factor in my choice will be the ability to use my beloved Takumars, albeit in manual focus mode of course. I understand that the K10 will do it fine, with an adapter, but how about the Canon and Nikon DSLR's? Do they also have adapters for the classic screw-mount lenses of yore? And will the metering systems work properly? (though I could use my Pentax spotmeter or the Goosen incident at times, like I used to do with B&W 4X5 work in the Good Old Days). Naturally I would want to have the full advantage of all those zones and whatnot in whatever body I decide on, but if not so be it. I very much have an open mind and very greatly respect all three camera makes that I mentioned (not that there aren't other fine companies out there but I'm down to those three most likely at this point). Besides the trusty and bullet-proof (indeed, elephant- and rhino-proof ....) Spotmatic, I own the Canon A2 and it fully lived up to expectations for many years but my EOS-mount Sigma 28-200 can't be re-chipped (way too old). I have always respected Nikon greatly, having used many Nikon microsopes for cell culture work in the lab for one thing. If there's another thread that addresses this specific topic I've missed it and I apologize - we can shut this puppy down right away then. Hate to see my rep go south so soon after joining this here fine forum ........ Charles.
