As previously, both lenses are really swinging at f2.8. Taking samples from across the frame and scrutinising captures at magnifications of 66.7–200% on screen are necessary to get an accurate flavour of the subtle differences between the two lenses. On balance, the cleaner mid-tone contrast swings me in the ZF's direction, but both are superb.

These corner tests are compromised somewhat by the fact that one – or both – of these lenses isn't really 85mm. The Canon is a notch shorter in focal length than the Zeiss, and therefore the stamp target falls just outside the problematic extreme corner. Making allowances for that puts them pretty close to level pegging. If pushed, I'd say the Canon L is still sharper than the Zeiss ZF in the corners at f2.8.
