Sounds like they fobbed you off. I use a couple of Pentax manual focus lenses on Canon EOS digital cameras, and they work fine using stop-down metering mode in both manual and aperture priority modes. <http://www.cottysnaps.com/snaps/mods/eoskmount.html> Note that a Canon EOS (body) to Canon FD (lens) adapter will have an optical element in it, and you would have to source one of these - perhaps not easy? Adding extra glass into the equation between subject and sensor is not going produce the best quality images, and maybe the same could be said for using a Sigma mirror lens ? It would be much easier to source an EF mount mirror lens either by Sigma or Tamron - or even (dare I say it - Canon ? ;-) The only reason I use a couple of old Pentax manual focus lenses on a top line camera is because the Pentax A* lenses are top quality, and 85mm at f 1.4 is an excellent portrait lens. Plus there's a bit of nostalgia to it - I love the old-style feel. That said, it only comes out to play in certain situations - the majority of the time I'm using Canon optics. But back to your original question - mounting a manual focus lens onto an EOS digital would not be a problem (assuming it can be made to fit with/ without adapter etc) - the camera does not need to know information about a mounted lens for it to work. The camera will work quite happily and let you adjust aperture and focus while it records your efforts. It's *trusting* you :-) HTH Cheers, Cotty ___/\__ || (O) | People, Places, Pastiche ||=====| http://www.cottysnaps.com _____________________________ * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
