Whoops, that's right, I didn't mean to do that. But what I did mean to do, and did, was switch the prime to the right for the 35mm shots in the 2nd set. So in the 2nd set, the shots from the prime lenses are on the right. I wonder how many people picked up on that for the 35mm comparison...
Originally posted by Pentaxor I think the great potential of the prime sales would rely heavily on the compactness factor nowadays. although fast aperture would remain as the main selling point.
Originally posted by Edgar_in_Indy I regard primes as being most useful for specialty purposes that are not practical to achieve in a zoom...macro capabilities, very large aperture, very compact dimensions, etc.
It's quite interesting that both of you mentioned compactness as one of the advantages primes have over zooms, but personally, it's not something that bothers me. Here are the three lenses I used in the testing before, the Pentax FA 35mm F2.0, Sigma 17-50mm F2.8 and Sigma 50mm F1.4, with a Sigma 85mm F1.4 thrown in for good measure. The images are processed intentionally to crush the blacks and to hide detail in the lenses. Can you tell me which lens is which?
What if I put the lens hoods on, maybe that will help a bit:
