Why is it that models always look so unhappy?
More to the point....
First set of photos is under fluorescent lighting. Canon 5D Mark IV has Flicker Free mode to handle that well and be able to mostly avoid common under-exposure problems. The T6/1200D doesn't have that feature. I bet if they took 30 shots with each camera under fluorescent, the T5/1200D would have between 1/2 and 2/3 of the images seriously under-exposed... whilewith FF enabled on the 5DIV at most one or two or so images might show any underexposure.
The 5DIV also has a self-cleaning sensor. Hope the T5/1200D user enjoys doing sensor cleanings, because it doesn't have that feature.
Try using the AF of both cameras in Live View too, for video or stills.... Dual Pixel AF on the 5DIV will blow away the slow contrast detection AF of the T6/1200D.
Go out and shoot in low light.... the 5DIV can auto focus down to -3EV (moonlight)... at least two stops lower light levels after the T5/1200D has given up even trying to focus.
While you're out shooting in the dark, which camera will be better: The ISO 100 to 6400 (expand to 12800) range of the T5/1200D? Or the 100-32000 (expand to 50, 51200 & 102400) range of the 5DIV?
T5/1200D has, what, nine AF points? With only the center one the higher performance "dual axis/cross type"?
5DIV has 61 AF points... 41 of which are dual axis/cross type.
Try auto focusing a 400mm f/5.6L + 1/4X teleconverter combo on the T5/1200D... Nope! Won't work. It'll focus on the 5DIV, though, with up to 21 of the camera's AF points.
Want a big, bright viewfinder (pentaprism, 100% image coverage, 0.71X magnification of a full frame image)? Or is a small, dim viewfinder okay (penta-mirror, 95% coverage, 0.80X mag of an APS-C image)?
Don't get caught out in the rain with the T5/1200D! The 5DIV will shrug it off.
Shoot a lot of portraits? Wouldn't it be nice to have a vertical battery grip with secondary controls that will make it more comfortable? Fit a BG-E20. That grip will also double the camera's battery capacity and the number of shots you can get before you need fresh batteries. It's CIPA rated to do 900 shots with a single LP-E6N 1865 mAh battery... so 1800 shots with two. The grip also is nice for better balance when you're using big lenses.
There's no grip available for the T5/1200D, so there's no way to increase its rating for 500 shots per charge with its smaller 860 mAh LP-E10 battery (there's also no grip is avail. for SL1, SL2, SL3, T6, T7, T7i or 77D, either... Oddly, one is avail. for T6i and T6s, T5i, T4i.)
Want a camera rated to last 200,000 shutter actuations? Or one that's rated for a 75,000 click life span?
Do you like direct access to various settings and functions like the 5DIV offers? Or are you okay having to push multiple buttons to get the basic camera settings, as necessary with the T5/1200D?
Need a top shutter speed of 1/8000? Or is 1/4000 fast enough?
Do you want 18MP images or 30MP images? Want to shoot continuously at 3 frames per second or 7 fps?
Okay with you if the buffer fills up and the camera has to pause to clear it after six shots (2 seconds)? Or would you prefer to be able to take 21 shots (3 seconds) before there's any delay (with some folks using fast memory reporting even more)?
Is 1080 HD video at 30 fps okay? Or would you rather have 4K at 30 fps, 1080 HD at 60 fps and 720p at 120 fps?
Single SD memory card slot? Or dual slots where you can use both SD and CF?
You get the point. It's a rather absurd comparison. Two very different cameras! (Maybe they should compare the T5/1200D with the 1DX Mark II or the 5DS-R instead!
