I'm posting here because I don't want to thread jack any more than I already was Ok, so because I'd never noticed distortion, I took 3, similar as possible shots of my 4 year olds face with a 100mm, 35mm and 28mm. Of the 3, the 35 was the closest resembling her face. The 100mm her face was wide, and the 28 just looked goofy <3 I'm not even sure what I'm asking. Or what the point of this post is. I guess, as far as primes go, does 50mm make that much of a difference? Is there only distortion when your up really close?
