guys wanna ask...
Sigma 12-24mm F4.5-5.6 EX DG,
Sigma 8-16mm F4.5-5.6 DC HSM,
Sigma 10-20mm 1:4-5.6 EX DC HSM,
Tamron SP AF 10-24mm F3.5-4.5 Di II LD Aspherical (IF),
Tokina AT-X Pro SD 12-24mm F4 (IF) DX,
Sony AF DT 11-18 F4.5-5.6 D
the lens above, let's don say about ff len or aps-c lens. their performance wise, wat difference can u get? i viewed some reviews and it seems they all get almost the same softness at the edges.
siggy 10-20mm seems to get sharp at both ends of the zoom but not in between.
tokina's flare seems horrible.
tammy's sharpness seems poor.
so basically, i think all are almost the same. but which is the best buy??

i may have overlooked stuffs. pls tell me so.
