How does it compare for photography, portraits, landscapes, image quality, dynamic range, and 4k video? The most important differences are the classic debate between DSLR and mirrorless cameras: things like an optical viewfinder vs an electronic viewfinder and lens sizes. Sensor stabilization and a flip screen make a big difference, too. We test the Canon RF 15-35 f/2.8 L, RF 24-70 f/2.8 L IS, and Canon RF 70-200 L IS.
