Canon EF 16-35mm f/2.8L USM (已停產)

1. f/2.8
2. Light and compact
3. Good sharpness and color rendition
4. Widest zoom L lens for FF DSLR body
5. Really fast and silent AF
6. Vignetting is not a problem in my Mk3
6. Can be used as a good landscape lens at 16mm and portrait lens at 35mm(2.8)

1. Suboptimal QC, I tested 5 copies and only the last one is tack sharp at center AND corners, therefore be careful, but once you got a good copy, it is really very good.
2. Mild to moderate BUT acceptable distortion at 16mm.
3. Relatively expensive

Overall, this is a good ultra-wide lens! The 2.8 is not too relevant for landscape but is a plus for low light photography / portrait. The brokeh at 35/2.8 is not bad and can help isolate the main object well. The price is a bit high and if your budget is not too tight, go for it, you\'ll have no regret. Remember the QC issue.

1. F2.8恆光圈,
2. 對焦快而靜,
3. 散景都好靚,
4. 16好正如果係Full Film真係正晒,
5. 成像好好中心位好利. 80%位都好利.
6. 防塵,
7. 同手感好好.

1. Full Film時邊緣有變形但可接受水平.
2. 邊位唔夠利,(但真係需要嗎)

支鏡成像好靚,但邊緣位係有少少變形同唔夠利,
不過真係需要嗎?

- F/2.8 光圈令對焦更快更準確

是zoom 鏡
f2.8

成像一般. 沒辦法, 因為太wide 了

canon 於AF 中只有2支紅圈wide zoom

但這lens 成像邊緣較散和有較明顯的變形...

若可以用定焦的話, 試一試prime wide

輕,夠wide,夠利,對焦快,用料一流,色實

貴.

廣角變焦鏡之中是皇者
