Pros:
|
combination of focal range+IS+f=2.8
|
|
Cons:
|
price,wide open soft corners at 17-20 mm and blue color fringes at high contrast edges
|
|

First and most important: optical quality in the 17-40 mm at f=4.0 is at least on par with the 17-40/4.0L. Everything else is an addon.
Wide open in the range from 40-55 mm pictures are almost tremendous.
At the short end (17-20) corners are a little bit soft (f=2.8) and obviously benefit from stopping down. CA is less than with the 17-40/4L
My copy is currently at the Canon service center due to a strong backfocus on my 20D ( was working perfectly on my wifes 350D). The neverending story .....
Final words of wisdom: optical quality ist excellent ( some weakness wide open at 17mm in the corners). The combination of focal range, F=2.8 and IS is even better then excellent. It is a high quality workhorse.

mine had a terrible backfocus at 70-100 when I purchased it. I sent it in for calibration and now have something like a perfect telezoom

Pros:
|
very good from F=2.0 on, FTM
|
|
Cons:
|
quite soft 1.4-2.0: much CA wide open
|
|
|
its now my third copy of this lens. No. ! and 2 were incredible: AF was absolutely unreliable. No. 3 now is much better: AF hits perfectly in about 90 % of all shots with f=2.0.
Expect quite soft sharpness between 1.4 and 2.0. If you compare it to the EF 50/1.8 I or II, the 50/1.4 clearly wins at f=2.0. Stopped down there is not much difference.
Conclusion:
Best EF-Lens (50 mm) around f=2.0, FTM is very handy when you need to refocus.
