Ok....so I actually wish I hadn't looked, as last time I had checked, Canon APS-C was on par with Sonikon. But, looking at the A6500/D7500 vs 80D/M5 (I didn't see Canon's SL2, which would be the latest), SN ratio is similar, but the Sony pulls away in the other categories. So, 80D is taking some great pictures, but you might want to at least rent one of the others if you go to a smaller system.

Also, to get this out there, but I've been playing with smaller cameras as it isn't practical for me to always have my dSLR system with me, and I am happy with the M3 system. The sensor is absolutely better than the 7D, the lenses are very nice, especially the 11-22. But, more surprising to me is how good the G7X II is. Two quick examples:

Point being, maybe you keep your FF gear, but get something small to take with you some of the time. That is essentially what I am doing and I have been very pleased having these different size/weight options.


That said, ergonomics do help. I've only moved the camera from around my neck to my shoulder but I was glad to do that. I use a blackrapid strap, but there are others systems out there:

An option I recently saw people hyping a bit that would get the camera weight off your upper body altogether would be a holster:

or, a belt system:

Anyway, really do feel bad about your situation and wish you luck. Smaller systems are very capable, but I would also consider more ergonomics in how you carry whatever system you end up with.
