I'm interested to get myself an UWA lens. I did search through some review and i'm down to two of them based on the cost and quality (compromised of course).
1) Sigma 10-20mm F4-5.6 EX DC HSM
2) Tamron SP AF 17-35mm F/2.8-4 Di LD Aspherical (IF)
3) Tamron SP AF 10-24mm F3.5-4.5 Di II LD Aspherical (IF)
I'm also interested for this as well
Sigma 17-70mm F2.8-4 DC Macro OS HSM
I wonder has anyone here has used the above lens b4? mind to give some comments?
