A7III has no advantage in size and weight. Do we go mirrorless just for the sake of it? Canon/Nikon may be better off making traditional FF DSLR (which is their strength) and compete based on function and performance.
Ah, I fear you're stuck in the old "FF Camera = big body + 24-70 2.8 zoom" mindset.
There is no advantage in size and weight if that's all you do day in day out. Perhaps the average wedding photographer wouldn't find a weight benefit in the A7III.
But attach a compact prime to the A7III, something like the 35mm f/2.8 Sony-Zeiss, or their wonderful 55mm f/1.8 portrait lens (which is an order of magnitude better than the Canon 1.4 50) and go have FUN shooting without that huge brick hanging from your neck all day.
The advantage of mirrorless in weight is this flexibility. It's
no worse when you have to stick your 24-70 on for your day (or weekend) job, but when you want to have fun, stick on a light lens and it's as if it's a totally different camera.
Of course, that's not the only benefit of mirrorless.
For me they are:
1. Ability to review photos through the viewfinder.
2. Ability to manual focus with focus highlighting through the viewfinder.
3. Ditto, with zoom
4. B&W photography with the viewfinder in B&W. And on my M3 which is converted to infra-red I get real infra-red images in the viewfinder.
5. Much better idea of how your levels look on bright days
6. Automatic face focus through the viewfinder (and, on newer models, automatic eye focus). I can't stress too much how amazingly useful this is. If you're a wedding photographer it may be worth the investment in mirrorless for this feature alone.
The weight and compactness are great benefits, but far from the ONLY benefit.
Now, will canon do an EF mount mirrorless? I doubt it because:
a) If they do, they'll sell more of these bodies to EF lens owners, who won't need to buy new lenses.
b) IF they do a new mount, they'll sell fewer bodies, but those people who buy them will buy more lenses.
Now, I'm pretty sure that Canon make a higher markup on their lenses than they do on the bodies. Which way will Canon go? It's not difficult to figure out...
