One thing that jumped out at me about Roger's new article RE: the 5Ds/5dsR was that fact that the Otus 85 outresolved the 300L by almost 24% in the center (on the 5D3). The Otus 85 was stopped down to f/2.8, so that is an advantage, but still... The 300L is one of the sharpest lenses in the world, period.
Those who wanted to see some resolution numbers for an Otus on a high megapixel body should take a look at the numbers here.

So there you have it, the 300 f/2.8 IS II is 19% sharper in the corner, 5% sharper on average, and within 7% of the Otus in the center. It must be a truely artfull-er ... lens ... with even more beautiful drawing, and umm, It's probably got that magic stuff too.
I suppose if you stitch (16) 300mm 2.8 pictures together you end up with (1) 75mm f/0.75 composite.
Factor in a bit of overlap and you may end up at 85mm.
16 times the resolution of the Otus. not to mention at f/0.75 v.s. 2.8
Stop the otus down to 1.4 and now the differnece is presumably well over 16x in favor of the composite.
And I don't think anyone cares because who is going to seriously stitch 16 images together?
Back on topic - isn't the 55 sharper than the 85 though? For some reason I thought it was....
Thanks for the fence post Eldar - is that the 55mm OTUS? - It was interesting to see the amount of green in the background bokeh, v.s. purple in the foreground bokeh. I would have guessed this to have been from a different lens. That said; do the competing lenses look substantially worse under those conditions?
The amount of vignetting looks like what I would expect.
P.s. Anyone else notice the fly that happend to be right near the focus plane on the left side of the frame?
