+ CANON 10-22mm f3.5-4.5 vs TOKINA 11-16mm f2.8 SHARPNESS TEST +

I did a sharpness comparison between two wide-angle lenses.
最近做了兩支廣角鏡銳利比較。

Left: CANON EF-S 10-22mm f/3.5-4.5 USM
Right: TOKINA 11-16mm f/2.8
Basically TOKINA 11-16mm is a little bit taller and heavier.
基本上TOKINA 11-16mm 比較重也比較長一點點。

Here is the look with lens hood: CANON's hood is noticeable large.
裝上遮光罩的樣子：


The camera used for testing is CANON T1i (500D). Focus point was set at the center of frame. Here are the test images:
我使用CANON 500D測試，對焦點設定在正中間。接下來就是測試的影像：
FOCAL LENGTH: 10mm for CANON/ 11mm for TOKINA
APERTURE: f/3.5



CENTER(100%CROP)




CORNER(100%CROP)




FOCAL LENGTH: 10mm for CANON/ 11mm for TOKINA
APERTURE: f/5.6



CENTER(100%CROP)



CORNER(100%CROP)



FOCAL LENGTH: 10mm for CANON/ 11mm for TOKINA
APERTURE: f/8.0



CENTER(100%CROP)



CORNER(100%CROP)



Both lenses are sharp at their widest focal length. However TOKNIA 11-16mm seems less sharp at aperture f/3.5.

這兩支鏡頭都算很銳利。但TOKINA 11-16mm 似乎在光圈f3.5的時候，表現比CANON差一些些。
