It's a 28mm wide.
It's a 105mm macro
It's a f2.8 at wide angle.
because of this lens, I sold my 28mm, 50mm macro, almost.
because of this lens, I give up buying the 70mm macro and 105 macro.
f2.8 DoF is too shallow for macro sometimes, f4.5 and 105mm focal length seems the best combination for me.
18-50mm f2.8 too short. 18-125mm too dark. This 17-70mm is the optimal for most use.

缺點:
OS OS, please update to OS version.
must buy HSM version.
be careful of bias lens elements out of focus. I read about (most Sigma lenses) some of this lens being frame left and right different sharpness, or frame up and down different sharpness. Must check before buying.

但係a16 應該sharp過佢
好過canon 支17-85 kit lens

好方便而又唔貴既一個選擇
裝左上機唔想拆.
以前用KIT..一入室內就要換50 1.8
E+基本唔冼.. 入到室內都夠用
搞到支50 1.8少左好多出場=P

優點:
微距好正(可以買小一支鏡)！成像,色彩,鏡身質感比Canon原廠400d Kit 鏡好！對焦快！焦距夠寬！影人,影景,旅行,用一流！包傘光Hood！
缺點:
2.8光圈只在17mm時出現！72mm濾鏡比一般58mm濾鏡貴！
評價:
很好！若用在Nikon Body 上有HSM更好！
優點:
包括左廣角至人像所需要的焦距, 方便旅行用, 自己用的係400d, canon鏡就無呢一段。光圏在17-20mm 有2.8, 最低f4.5, 非常夠用。
輕身, 唔會覺得太重, 旅行唔帶佢點對得著自己?

色彩唔夠shape, 對焦比較慢。
但係2千幾點同d L鏡比?

去旅行, 無理由帶支貴鏡頭, 一支17-70有埋macro, 正~
但係sigma係會比較色盲, 色彩唔係太得, 好在我本人係叻係photoshop多過影相, 所以無乜大問題。當然如果轉左full frame的機又另當別論, 到時canon 的L鏡就係首選。
當然, 一定要留返黎係旅行用(中國之類怕比人偷)。

我買呢枝鏡返o黎係replace左 400D 18-55 枝kit鏡..
個人新手而言覺得枝鏡好夠用..唔駛換鏡都可以隨手影下花花草草等macro相..而且仲有大光圈試玩下..~
呢個價錢可以有咁多野玩..ok ar..!
