Quote:The "affordable" "medium format" digital cameras only have a 0.79x crop factor... So that means you only need a 633mm lens as 500mm FF equivalent. Something like a Pentax SMC A* 645 600mm F5.6 ED. Discontinued, no AF and no IS. Yeah, Toni is onto something. :blink:
OK 633mm! To be quite honest good as an idea it may be..............Toni it's all yours!!
Please don't hesitate to let us know how you get on with it!
