yep, i also purchased my K100D with the crappy Sigma 18-50 kit lens, and ive ended up bidding on obscure, oddball lens to try and get around the ridiculous prices people are willing to pay for SMC glass...im only new to SLR photography and on a limited budget but id like to think i could occasionally find a bargain on a reasonable fully manual 24 or 28mm wide prime..
arfter giving my Sigma 18-50 its last chance last night on some lightning, and being disappointed miserably (bloody thing is soft as set at 5.6 and infinity...)im thinking i could stick that lens on the bay to help build up my pay-pal fighting fund...im sure someone would pay ridiculous money for it...
of the oddball lens i have won, i think the tokina SZ-X 630 (60-300mm Pentax KA-Ricoh RK mount) , once i worked out the issues was the best value at $46 including postage...even then some judicious file work was required so it would mount on the Pentax...
