Another question that I have, and I apologise if this sounds extremely "dumb" BUT, if the effective focal length of the *istD is 1.5times the focal length of the same lenses on a film body, does this mean that the f-stops are also 1.5 times? ie. If I used my FA 50mm f1.7 on the *istD, would this effectively become an "FA 75mm f2.5" and would the FA 28-105mm f4-5.6 become a "42-158mm f6-8.4", cause if so, that would suck majorly. (sorry, I'll write the words "lollipop" and "straw" here so that I don't get into trouble for using the S word out of context! lol). And all of my lenses would then become very slooooowww. OR, does it only affect the focal length? Anyone able to get this through my thick skull? lol.
