I am out for a new wide lens. The 2 lenses which made it to the top for me are
Tamron SP AF 10-24mm F3.5-4.5 Di II LD
and
Pentax smc DA 15mm f/4 ED AL Limited
I sure know they are not of the same category and I am fully aware of the differences between them.
I read a lot on the net and compare sample images - that's the best one can do in order to get information and decide.
The important factors for me are sharpness and true to life colors - and here is where I ask for advice.
When I compare full size images from DP Review - I tend to think that the Tamron lens is sharper than the Pentax.
Is it true?
How good is the Tamron lens in terms of sharpness and colors?
How do they compare?
Does anyone have any experience with both?
Samples to compare?
