Does the current EF 50mmf/1.4 have the sharpness needed for higher MP counter see with every new body?  Isn't there any pressure to release an update for that reason?

It looks like mush on a 5DS R ,especially wide open, on TDP.

A "battered old copy" of a 50 f/1.4 USM was tested on the 5D3 / 5DS / 5DS R and though detail did improve on the higher res bodies, the jump up was less pronounced than with other higher quality lenses that they looked at.

Although currently not interested back in the mid nineties I had bought a used EF50 1.4 in excellent condition.
I started using it when I realized some zooms quality suffered upon enlarging B&W photos in the darkroom.
So it had its share of use back then. Unfortunately it was in a bag that was stolen 8.5 years ago.

That's because it is following the laws of physics, who'd of thought of that?

Quote
System resolution can be broadly shorthanded down to this equation, it isn't perfect but pretty close.

tsr = 1/sqrt((1/lsr) ²  + (1/ssr) ² )

Where tsr is total spatial resolution, lsr is lens spatial resolution, and ssr is sensor spatial resolution.

So if, for example, we have a sensor that can resolve 100 lppmm, and a lens that can resolve 100 lppmm we get this

1/sqrt((1/100) ²  + (1/100) ² ) = tsr of 71 lppmm

Leave the same lens on, good or bad, and double the sensor resolution to 200 lppmm

1/sqrt((1/100) ²  + (1/200) ² ) = tsr of 89 lppmm

Why are people constantly surprised by these results when they all fall in line with mathematical predictions. Indeed if the results are different the first place to look is testing methodology or sample variation.
Too often we lose sight of the fact that photography is about capturing light, if we have the ability to take control of that light then we grow exponentially as photographers. More often than not the image is not about lens speed, sensor size, DR, MP's or AF, it is about the light.

For all the negativity and the pundits that wrote the 6D MKII off without even trying it, I'm glad for Canon and the cameras owners it came first. The camera is a good all-rounder doing most things without an issue, its not specialist like the 5DS / 5DSr and its not a full pro camera like the 1D X MKII or the 5D MKIV. However it does have one feature none of those cameras has, the articulating touch screen which in low landscape shots is a god send in framing etc.

The Canon EF 85mm f1.4L IS USM is both a pro lens and a keen amateur lens at a reasonable price point given its reviews on image quality and that all important IS. Not in my bag yet (although we have some in rentals) but will be in 2018.   
Canon 5DS, Canon 6D, Canon 6D MKII,16-35 f4L IS USM, 17-40 f4L USM, 28 f2.8, 24-70mm f4L IS USM, 24-105 f4L IS USM, 100mm f2.8L IS USM, 70-200 f2.8L IS USM II, 70-300 f4-5.6 IS USM, 50 f1.8 STM, 100-400mm f4.5-5.6L IS USM II, 1.4EX III, EOS 760D, EF-S 10-18mm f4.5-5.6 IS STM & others.

I did not say I was surprised to discover this.  I was reposting data that echoed ScottyP's point.

The Canon EF 50mm F1.4 has image quality equal to Sigma 50 Art ... When used in F8. But used in F1.4 aperture, it's simply mediocre.

Sure, but you also recognize it's just about the sharpest autofocusing 50 prime Canon sells, right?   

The 50L is a hot mess away from center and I'll take jumpy/hunting micro USM over the 50 f/1.8 STM's focusing speed every day of the week.

So I don't use the 50 f/1.4 USM because I love it.  I use the 50 f/1.4 USM because it's not the size of a pickle jar and it's the best of three first party AF options for Canon.

Given the rather limited selection of what was released this year for full frame equipment, there wasn't a lot to choose from. Number one on my wish list are sensors with a higher dynamic range. The 5D Mk IV is good, but there was no excuse for restraining the DR for the 6D Mk II.

Horses. It's a good thing you bought your equipment when you did. Nothing like horses to swallow up every cent you have.

Having had horses and boats for many years, horses are a distant competitor to a boat.

Mostly amateur/semi-pro shooters on here I guess, looking at the results?

Not sure.  2 out of 3 questions only had a choice of what was released this year, so that will naturally tightly box in / flavor the results.

But the wish list question was a bit more open-ended -- choices listed below.  What do you think the top vote-getter would be in a more pro-heavy pool of voters?  I contend that though pro folks are interested in mirrorless want a very different mirrorless rig than what enthusiast mirrorless people want, but they still want one. 

- A
MY order of preference to your interesting list

EOS 5DsMark II (upgrading my 5DsR)
EOS 7DMark III (upgrading my 7D Mark II)
135 f/2L IS    (upgrading 135 f/2L)
24-70 2.8L IS  (upgrading 24-70 2.8 II if and only if
the IS is better optically since the II zoom is really good)
600 DO IS  (OK this depending on price)
Mirrorless
70-200 2.8L IS III (my II version is very good)
200-600 (under revisement since I do have many white fixed lenses)
Anyway I find hard for this to be
1. Up to 600
2. f/5.6 at most
3. Cheap
But you can chose two out of 3 of the above :)

50 1.4 IS
EOS 90D (not interested)
EOS C100 Mark III (not interested)

Sorry for my low preference for the 50 it is not that I do not want it to be made I just prefer other items more.
Not that I would get all of them of course, this was more of a wish list. Some can be obtained I guess if I sell the current editions of the cameras and lenses I have but some like the super telephotos are debatable...

My list and your list are pretty close.  My list is

5DSR II (replace existing for landscape assuming improvements in DR, ISO sensitivity and maybe bump in MP)
7D Mark III (replace 5D Mark III as dedicated wildlife body)
600MM DO (replace very heavy 600MM II)

Beyond that I am good with lenses for the moment and the rest of my kit is solid. 
5D Mark III

+1 This is a solid birding/wildlife set. I got the 500mm 4L IS II for weight reasons. So the 600 DO would improve reach and size only. Still extremely tempting but the price will be huge I guess.

I still believe in a Canon EOS 3D, so in a pro revolutionary system, a DSLR body with a classic design, next to the Sony a9 (or a Canon F1N), not a mirrorless but coupling a large electronic viewfinder just above of the pentaprism with a rail system to focus through the back screen (like the EOS M5), more place to the nose (like the Contax 645 AF or Mamiya one), an electronic shutter speed (up to 1/32.000) and the rotating screen of aEOS 6D Mk II or like the Nikon D850... I don't think than Canon wants to create a mirrorless camera, is not necessary right now, at the moment there are four EOS 5D in the market (DS, DSr, mk III, mk IV), it's time to sell just a 5D Mk IV and create a camera to introduce to professional photographers to the future EOS 1Dx Mk III, a kind of a EOS 1v (body + booster). I know I am just dreaming about to believe than Canon is going to change his commercial strategy, but, it could be a right moment to make something different and traditional, at the same time...
