I recently bought a Canon Digital Rebel XT. My mother-in-law has offered me some of my late father-in-law's Pentax lenses. He was a wedding photographer, so he has MANY very nice lenses that I would love to have. Anyone know what sort of adapter/converter I would need? What would work best? Does anyone know where to find one? Or how much I would end up spending for one? Thanks in advance! EDIT: I found an adapter that I think might work... http://cgi.ebay.com/ws/eBayISAPI.dl...30003674618&rd=1&sspagename=STRK:MEBI:IT&rd=1 Is this the sort of thing that I'm looking for?
