Canon EF 17-35mm f/2.8 USM L - Review / Lab Test Report
31 October 2008
Conclusion: During my days with this lens I was actually quite fond of the performance of the Canon EF 17-35mm f/2.8 USM L but I usually limited the usage to focal lengths beyond 20mm. A good idea also confirmed by the MTF tests which showed a quite poor border resolution at 17mm. However, in the 20-35mm range the performance is very good and comparable to what we've seen from modern Canon ultra-wide zooms. Same goes for the other image characteristics.
