Canon EF 17-40mm f/4L
An illuminating review of this lens is found in DAP, comparing it to the following lenses:
- Canon EF 16-35mm f/2.8L II
- Canon TS-E 17mm f/4L
- Zeiss ZE 21mm f/2.8 Distagon (see Guide to Zeiss ZE / Zeiss ZF Lenses for in-depth coverage).
- Canon EF 24mm f/1.4L II
- Canon EF 35mm f/1.4L
The Canon 17-40mm f/4L is a compromise between price (about $750) and quality. Prime (non zoom) lenses offer better results in this range, sometimes much better, and the 16-35mm f/2.8L II is generally superior optically as well.
However, the 17-40 offers an attractive combination of price, size and weight, and will make a fine lens on cameras that do not have full-frame sensors.
