| p.1 #1 · p.1 #1 · 17mm shotout: 17/4 TS vs. 17-55/2.8 IS vs. 10-22/3.5-4.5 | |
After my initial disappointment from the 17/4 TS I decided to get a bit more serious. I took it again and compared it to my 17-55 and 10-22. I didn't test other lenses because these are the lenses which were available to me.
Caveat: I am not a lens tester by any means but I did try my best to keep everything else constant except the lens.
Test methodology:
Camera was mounted on tripod, which stayed stationary throughout the shooting.
Focusing was done using MF via 10X LV (i.e.. MLU) in timer mode.
Focusing was done only once for each lens.
Focusing point was the sign seen in the crops. As I only have an APS body (7D), I chose a focusing point which is close to the edges of the frame, to make the test a bit tougher.
RAW mode was used and pictures were converted to JPEG without any PP. Normally I sharpen my pictures because of the AA filter but here I wanted to avoid any manipulation, to get a baseline.
M mode was used and exposures were kept constant: F4 and 1/3000, f/5.6 and 1/1500, f/8 and 1/750.
Zoom lenses were set to 17mm.
17/4 TS was set to zero tilt and zero shift.
Order of appearance in this thread is constant: 10-22 first, 17-55 second and 17/4 TS last.
Here, the first pic is the whole image and later, the f/4 crops.
Happy shooting,
Yakim.
