Today I compared 3 lenses at 24mm. This was just a test of the sharpness of the lenses. Other aspects like CA, vignetting, contrast, colors, flare etc. were not tested. The aim of this test was to check, whether my new 24 TSE II lens has any faults and to help me to decide whether I should keep my 24-70L or sell it.
The test-object was the side-wall of my house. The test was done with a Canon 5D II on a Gitzo series 5 tripod with a burzsynki head, mirror lock-up and manual focus with 10x live view on the wall at the center of the image. The 24TSE was not shifted or tilted. All pictures were shot in raw at ISO 100, converted with LR with the default sharping parameters (25, 1.0, 25) and then exported to jpg with 100% quality.
The following 3 lenses were tested at 2.8 (3.5), 4.0, 5.6, 8, 11, 16, 22:
1. Canon 2.8/24-70 L @24mm
2. Canon 3.5/24mm TSE II
3. Nikon 2.8/14-24 (adapted with 16-9-adapter to Canon)

Pictures of the other apertures will follow. By the way the 24-70L was tested a few weeks ago at Canon and according to Canon the sharpness is within spec. Draw your own conclusions, but I am happy with my new TSE and the 14-24 and I will probably sell my 24-70.
Best regards,
Boris
