Yes, I had read the lens rentals article some time ago. The 35mm F2IS is probably the sharpest normally priced lens that Canon makes. It's possible to estimate its performance with the A7r because its performance is very similar to the Sigma 35mm F1.4, which actually has a higher DXOMark than the 35mm F2IS. DXOMark has tested the Sigma 35mm with the D800 that has a similar sensor to the A7r. The Sigma 35mm scored 23P-Mpix. Extrapolating, the 35mm F2IS will likely be around 24-25P-Mpix with the A7r since it's center is a tad sharper (edge performance trails the Sigma) and the A7r has no AA filter. So Canon's sharpest lens still trails both the Otus/D800 and 55FE/A7r by a considerable margin of 4P-Mpix. It also implies that Canon's sharpest lens cannot fully resolve 36MP. If so, what hope do Canon's lesser lenses have?
I've seen tests of the 135 F1.8ZA and while it's a very sharp lens, it seems to trail the Zeiss APO 135 F2 in sharpness. An APO lens should be better corrected. The APO 135 scores 28P-Mpix on DXOMark with the D800, so its pretty much a match to the Otus and 55FE.
Can only wait for canon's high MP full frame camera to be released in Order to know then keke. Canon's 5d3 cld already match so closely in terms of sharpness to nikon's d800 at 22mp. Let's see what the EF lenses can do when matched to a 36 or 40mp body.
D800 has aa filter n the a7r doesn't. Wonder y dxo doesn't test the Nikon lenses with the best sensor available on the d800e
