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.
