I really want to trade my Canon 5 d mk iii and a clutch of prime lenses in for an XT4 kit. I find the Canon stuff so heavy these days that its become a real issue. My Panasonic GX8 is getting far more use these days. What is really of concern longer term is that ef lenses have ceased development so even if I hang on, a change is inevitable at some point. The price of the R5 is excessive in my opinion and the R6 just has 20 megapix, which doesn't even match my current EOS 5D iii. If I change kit it means camera, 2 flash units, 6 lenses and canon accessories. Think I may need a push in one direction or another because I can't make my mind up. Oh those first world problems.
