So after reading several lenses reviews from different users and websites to be used on a K-5, I still need your help to decide between the following competitors, and please, do note that I'm not taking in account any other lenses, but this ones, where the main purpouse will be IMAGE QUALITY (SHARPNESS).
So DON'T worry about their price, angle of view or utility
I'm just looking for short answers from users that have already used any of this lenses:
Sigma 17-50mm F2.8 EX DC OS HSM
vs
Tamron SP AF 17-50mm F2.8 DI II XR LD ASPHERICAL [IF]
Tamron SP AF 17-50mm F2.8 DI II XR LD ASPHERICAL [IF]
vs
Tokina AT-X 28-70mm F2.6-2.8
Sigma 18-250mm F3.5-6.3 DC OS HSM
vs
Tamron AF 18-250mm F3.5-6.3 DI II LD
Thanks in advance for your time... =D
UPDATED: I got my answers, thanks everyone! =DD
