Some neat links there Sassan. thanks.
There's some real problems that'll be encountered converting FD lenses to Eos body, AND maintaining distant focus, as you've posted already. The FD breech-lock design doesn't make life easy for adaption. (for those unfamiliar, the FD system lens mount looks like it some be on the camera body. Likewise, the bodies had 'protruding' mounts, similar to, but not quite as 'sticky out' as normal lens mount of today does.)
Have seen a few big white FD ones go cheap as chips. Unfortunately I've no links to it, but saw similar with another 'long tom' big FD fit glass (maybe same one you saw Sassan?)....A massive Canon 600mm FD mount lens had been striped back at the body end, so accepting the ultra common M42 screw thread accessories (Pentax Spotmatic,Praktica,Zenith, and some current Voigtlanders)......as I remember, it had a history of being used on movie making equipment. C mount rings a bell?, but I'm thinking it might have had the common M42 lens to Eos/EF body mount adapter then fitted to it, and the AF confirm chip stuck to the adapter?
I've not yet seen any smaller lens stripped back, but kinda guessing the long tom prices, design (and with more barrel material to hack off), lends them more to some seriuos adaption work?
In terms of chips, adapters etc, ebay is a great / economical sourse, but SRB filters have a history of pretty radical conversions....tho a bit pricey
Seems a shame that loads of FD stuff goes for peanuts......similarly some Minolta AF lens mount stuff was going the same way in the S/H market, until Sony stepped in!
crickey!...hadn't realised how cheap those FD-EF adapters are!.....full of eastern promise?!lol
