Leica m ev1 vs sony a7r vi?
The Sony a7R VI is the easier camera to live with. It has autofocus, in-body stabilisation, a fully stacked sensor that shoots 30 frames per second, and a huge Sony E lens range. If you shoot sport, wildlife, or anything that moves, it's the one I'd pick.
The Leica M EV1 is for people who want a slower, more deliberate way of working. It has no rangefinder, so you focus manually through its electronic viewfinder, and it has no stabilisation in the body. Its 60 megapixels are close to the Sony's, and the Leica M mount has a long lineup of lenses. A lens like the Leica APO-Summicron-M 35mm f/2 ASPH suits it well.
For a fast, versatile kit on the Sony, try the Sony FE 24-70mm f/2.8 GM II. My pick is the Sony for most people, and the Leica for those who enjoy the process.
