Canon TS-E 24mm f/3.5L

Review Date: Nov 30, 2011 Recommend? yes | Price paid: $887.00 | Rating: 6 

Pros: Very sharp in the center, beautifully made.
absolutely atrocious in the corners

The center sharpness of the lens is very good but at about 2/3's out from the center the image really degrades, and stopping down even to F11 doesn't help. I could live with wide open performance being poor but I thought it would improve stopping down and it really doesn't. I have also read many reviews discussing chromatic aberration and although its there it isn't very pronounced. I am shocked that a fixed lens with a slow maximum apeture and considered an L lens could be this bad, and thats before shifting, when shifted the problem is even worse. I don't think there is anything wrong with the lens because the center is acceptable but this thing is worse than my 24-105L or 24-70L and its not even a zoom.

Pros: extremely sharp and contrasty
zoom ring backwards from Canon

I shoot for a living and my canon 24-105 has had alot of use the last few years so when I saw this lens on Craigs list locally I picked it up as a back up. Maybe I just got lucky, but this thing is extremely sharp and contrasty at all f-stops and focal lengths. Its as good as any L series zoom I have ever owned and I find myself using it often, even though its the only off brand lens I own. The zoom is reversed from Canon zoom ring and frankly I find this aspect of the lens very frustrating, but other than that I highly recommend this lens.
