小弟用左400d+17-70年半!
有以下總結!
1.17-70的範圍十分實用,所以長插了body年半!
2.2.8大光圈在室內的確好用.
3.可以玩Marco
4.廣角對比同級鏡一點也不嚴重,比起我現在的17-40L還要好!
5.對焦算得上快,成象比預期的好!
6.鏡身少有甩皮,SIMGA出哂名甩開!
7.二手價還可以,2.8K入,用了年半放到1.7K左右,圍到130元一個月

優點:
缺點:
1.副廠鏡通病---迷焦(focus左在係主角後的背景),越用越迷(用了1年後問題才變得嚴重),通常影3張炒兩張,一定要光圈收到4.5,用24mm才有改善.(已拿去simga修理,問題已改善)
2.都係SIMGA通病,出來的相,偏少少黃!

評價:
17-70不失係一支好鏡,1.7k二手價有咁的質素是超值!
但副廠鏡終是副廠鏡.有能力的話還是買canon鏡,好似我用了17-40後無哂迷焦的苦惱!安心捕捉表情!

Tamron A16 or Sigma 17-70?
It is hard to choose.
I asked myself.
Are you need a Marco function? YES.
How many photo you need the range 50-70mm? about 30%
OK, go ahead to Sigma!

優點:
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.

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
