The latest Canon zoom - the 11-24 zoom - really struggles with the 50Mp camera, and you better not be looking for even half decent corners from it at any FL/aperture, and it has a serious CA issue too:

PZ would not even give it a rating:
"That all being said ... what's the conclusion then? Honestly at this stage we'll not provide a further guidance because we just haven't tested a sufficient amount of lenses on the EOS 5Ds R yet. However, while many lenses can rule the common 20mp sensors, we can already say that Canon's new 50mp sensor is here to rule em all - less so in the image center but certainly so in the outer image region."
It's not the intention to knock Canon here, I have kept to observable facts. They do pretty well for a mainstream lens maker with a long term near-monopoly and a consistent disregard for outer frame resolution. In fact many Canon lenses deliver great IQ wider than f4 only for the area under their AF spots which, like Emperor Penguins in winter, all cluster tightly in the center of the 24x36mm frame. These AF spots appear to cover little more than 20% of the frame, in even high end models.
So you have to wonder. Zeiss and Sony are busy ensuring even their affordable contemporary lenses work across the entire frame. We see this in the RX1, FE55, both Batis lenses and the FE90. You can observe this design choice in the MTF for the new WA Otus and B25 - flat lines almost to the edge, from wide open, no less.
It looks like a difference in imaging philosophy married to focus abilities, and very few a7rII users complain about corner definition in those FE/CZ lenses listed above. Sony cameras of course enable you to focus very close to the frame's edges, rather than rely on 'focus/recompose' with its various deficiencies, now exacerbated by high resolution.
Canon also are taking-on average-20-25 years to replace/update many of their high utility prime lenses:

I'd love to sing their praises, but they do have to deliver in order to earn that praise. Anyway, we can wish them well, and hope they learn from the leading lens makers and from Sony, who are very lucky to have CZ 'in their corner'.
On topic, the MTF for the Leica super zoom are very good indeed. It's certainly impressive in that technical sense. Correction is here to stay, I am afraid. Designers will, in general, make good choices in the trade offs involved. ...Show more →
Philip, I said that because I have wide experience about using different lens from Nikon consumer, pro zoom up to high end Leica S and OTUS glass. I don't do pixel PP usually, but I did test lens at first few days I got it on hand so that I can understand its character to use it wisely. I can telling you 14-24 Nikon copy I had can compare head to head 21mm and 15mm Zeiss I saw on line. (I never shoot SWA Zeiss myself, but did research before buying 14-24mm. ) I do found a few online comparison with 15mm Zeiss and 14-24mm Nikon. They are comparable with plus and minus to each own. and remember Nikon is a zoom that you have 14mm, 16~24mm in addition to 15mml.
If 11-24 is at same or better level than 14-24 as indicate from a few review I read, it will be another wonder in lens design I feel. I am still look forward to see Zeiss or Leica's 11-24 to come. while, if they finally come, you want guess how much they charge. I can tell you if THERE IS such a Zeiss/Leica lens, you are looking at 10K plus.
The SL 24-90's performance is not a surprise to me because I know for the price point, Leica has no magic to beat Canikon. I look forward to see comparison between Leica 24-90 with Canon 24-70 or new Nikon to prove I am wrong at the same time I am waiting Zeiss to come up a zoom.
I think Canon especially did a very good job recently. Their newly introduced 24-70, 16-35f4, 11-24 all seems wonderful. The all review I read the 16-35mm f4 Canon is better than Zony 16-35mm which is the best zoom out of sony Zeiss. and new 35LII might be the best 35mm lens ever created. (well, maybe RX1 is as good.)
knowing how sharp my Nikon 85mm f1.8G can be, and how sharp my recent got 20mm f1.8G is, I have to say Canikon have really good lens designer know how to work with limitation to create great tool, that is truly good engineer to me.
Don't forget Sigma, look how they did with 50 art at 1/4th cost of OTUS? I am not a fan of their rendering, but to say I am impressed is under estimation.

I would need to push some DNG files to form an educated opinion on whether or not this camera meets my personal needs. It would be great to be able to rent one for a week and see how things work out. For myself, the handling and overall enjoyment I get while using a camera is equal or more important than the resulting image.
