I've shot the z9 and it's pretty amazing but definitely not perfect. The teardown was pretty cool, always wonder when they put it back together if it still worked.

Shooting sports side by side with a D5, pro level mirrorless has more to improve upon. The pro dslr's canon 1Dx series and Nikon D4,5,6 series are big and heavy, but that size all translates into a single battery that shoots 3000-5000 shots and numerous custom buttons to quickly change a variety of settings fast which is important. Most have never experienced shooting with these bodies but are quick to whine about every aspect. When it comes to getting a shot they are indispensable with sports, wildlife, events because they just work. Especially in poor weather conditions.

Since covid I skipped the canon 1dx3 upgrade and after shooting the z9 will skip the r3 now. Still sticking with Canon but will wait for R1 in hopes the EVF is flawless when panning shots.

Spot on that these are not hobbyist camera's, but when do you get shoot with them everyday they definitely serve the intended purpose well.
