Hi there!
I'm thinking about getting a good wide angle lens. I definitely want an autofocus lens, and I'm considering getting the
SMC Pentax-FA 28mm F2.8 AL, the
SMC Pentax-F 28mm F2.8, or another good 28mm or 24mm lens. I want specifically those focal lenghts as that's what I normally use and because I think I can get something like this in the price range I want to spend, between 200 and 250$.
I want it to be prime because I'm looking for sharpness and color rendition, and I know those have very good qualifications in that field.
My doubts come when I've seen very good reviews for the
Tamron AF 17-50mm f/2.8 SP XR Di II LD Aspherical, on which is mentioned that this lens have really good sharpness and color rendition. This lens is slightly above my price range, but I wonder if the sharpness of this lens is equal to that on the prime 28mm when using the same focal. If that was the case, or very similar, then I'll get the Tamron giving the fact that it offers me more than the prime in relation.
What do you think? Do you believe the sharpness of the Tamron at 28mm is equal, or very similar, to that on a 28mm prime?
Thanks everyone for your help.
