This page compares the EF 17-40mm f/4L to the 16-35mm f/2.8L II at 24mm, using the Canon EF 24mm f/1.4L II as a reference lens, previously reviewed here. All conclusions are based on viewing images as 16-bit TIF in Photoshop, processed from RAW.
- The 17-40mm f/4L was a brand-new lens, supplied for testing by our trusted vendor B&H Photo.
- The 16-35mm f/2.8L II was my own existing lens, one I had thought to represent about as good as one can expect, based on multiple prior samples of the original 16-35mm f/2.8L, yet with this testing revealing itself as flawed.
- The 24mm f/1.4L II was rented from LensRentals.com.They are very reliable, and offer lenses and cameras from Nikon, Canon, Leica, Sony, Zeiss and more.
