Stephen, I'm curious about a couple of the points Daniels made.

#2 Since the sensor size effectively turns a 21mm into a 28mm when do we 
start to worry about vignetting? If it vignettes do we have to worry 
about edge sharpness as well?

#3 If one has to hang a TTL flash on a 35mm might as well be an auto 
focus digital  SLR?
