The default specs on the 5D4 are great, not amazing but people are overhyped for the D850 just because it’s an A7R that can actually autofocus.
Watch what happens with the 5DSR MkII.
I had to think twice before I snagged the 5dm4, because it was a bit over budget.
I didn't want to buy a 6D and 5Dm3 because of missing touchscreens and the inability to use M mode with auto iso.
I didn't want the 5DSR because the files are too large.
I didn't want the 6Dm2 because of the weaker Auto white balance
I didn't want the 1DX because there are no discreet bags on the market for those cameras, (although I still own a 1DS).
I didn't want the 1DXm2 because of $$$$
I didn't want the A9 because of $$$, missing Flicker detection and DP+ Highlight protection, have no Sony lenses =(
I didn't want the A7Rii because of too large files and focus difficulties indoor.
I don't want Nikons because all of their zoom lenses and Teleconverters are optically less than Canon. (Sold my last Nikkor prime lens 6 months ago)
At the moment Canon came with the C-log change, I would rather had Canon discontinued the 5Dm4 and came with 5Dm4 II without: 30 fps frame grap/video/dual pixel BS for
500$ less and 5DC with 7 Digic processor, C-log, 6,5K video and focus peaking for
5000$ more.
But the real thing is, in the Nikon world you can get the D810 which has lesser larger files and the D850 that has large files an modern features. In the Canon it is the opposite, the 5Dm4 with all the novelties and the 5DSR with the largest detailed files.
On paper all those Sony and Nikons look good, because they can change their Raw files from 14b to 12b /and or Medium/small etc. In those situation the A6500 and D500 look like they have a buffer of 1500 photos and 10 times outperform the 7Dm2 (35 RAW). But once you need to dial Iso up to 800, and set focus priority and 14b Raw, it is more like 7Dm2 20 raw pictures vs D500/A6500 55 raw pictures.
The A7RII and D850 are not really that much above the 5Dm4.
My biggest 3 disappointments with the 5Dm4 are:
+The manual dial near the shutter cannot change the AF area selection like the 6DII and 80D. Thats what they want you to use the Area selection dial for, but I use that one for exposure compensation.
+The shutter release button in the Canon app to trigger you camera via WIFI is too small. I always try to hide my phone when doing self-portraits, but my fingers keep missing the tiny button in the App.
+The feature: lens drive when AF impossible was set ON by default, which mades my older Canon EF lenses 28-85mm and 400mm F5.6 failed focus too much. Should have been OFF by default in my oppinion.
