I like Tokina more!

Known from various reviews and tests for comparing the 3 lens, Tamron's resolution is lowest, also it's max aperture is smallest F4.5.

Sigma 10-20 has the widest view degree but the max aperture is not fixed throughout the focal range. I had this lens before but sold. Image quality is acceptable.

The wide end of Tokina is only 12mm but it has fixed max aperture F4. Not used this lens before but according to the reviews read, it can provide sharp image even at full open aperture.

Same opinion as MN56 I prefer Tokina more.

Tokina 12-24 >> Sigma 10-22 >>Tamron 11-18
Tokina 12-24公不應求.訂貸都要排隊.
外國測評Tamron 11-18 評價最低.
