Canon eos r7 vs nikon z30?
The Canon EOS R7 is the one I'd pick for wildlife and sports. It has 32.5 megapixels, in-body stabilisation, and a 1.6x crop that brings distant subjects closer. Pair it with the Canon RF 100-500mm f/4.5-7.1L IS USM, which gives roughly 160-800mm equivalent reach.
The Nikon Z30 is a vlogging body, with no viewfinder, a flip-out screen, and 20.9 megapixels. It has no in-body stabilisation, so choose a stabilised lens such as the Nikon Z DX 16-50mm f/3.5-6.3 VR for an everyday kit.
If you want to check how a lens's focal length translates, the focal length converter does the maths, and the sensor sizes guide explains why both cameras use APS-C.
