喂呢支鏡質素只是一般,由於10-20mm關係變形都幾利害,
支鏡強項係夠wide,弱項係唔係好sharp.
如果買最好收細光圈.
後來放左買過支tokina 12-24mm.

都唔錯, 請參考 www.photozone.de
" Verdict
The Sigma AF 10-20mm f/4-5.6 EX HSM DC is a worthy alternative in the ultra-wide arena for APS-C DSLRs. At 10mm it showed some of the highest resolution figures that we've seen so far here whereas at 14mm and 20mm the results are slightly worse than the rest of the gang but still pretty good.
On the down-side the lens shows fairly heavy vignetting at large aperture settings. At 10mm there're some quite pronounced barrel distortions at the extreme corners (far less in the inner image field) whereas at 14mm pincushion distortions can be quite obvious.
It's a joy to use this lens with its excellent build quality, smooth controls and fast AF on top.

The alternatives in this zoom range perform quite similar so you've to consider your priorities. The Sigma AF 10-20mm f/4-5.6 EX HSM DC is surely worth a deeper look here. "

你係講10-20枝DC,定係佢另一次DG鏡,呢個係10-20 DC,sharp係差o的,但係色彩,變形都好正.
