Just published in DAP is an update to my review of the Canon EF 17-40mm f/4L and the Canon EF 16-35mm f/2.8L II ultra-wide zoom lenses. The latest addition compares the Canon EF 17-40mm f/4L to the Canon EF 16-35mm f/2.8L II and the Canon TS-E 17mm f/4L, including distortion, vignetting and sharpness across the full aperture range.
The 17mm f/4L shows its mettle, and it offers tilt and shift as well. Get the Canon TS-E 17mm f/4L at our trusted vendor B&H Photo.
Next up is a 24mm comparison with the Canon EF 24mm f/1.4L II.
