"original FE 85mm f/1.4 GM lens, which has been praised for its exceptional image quality"
Reading Sony PR too much?
This lens is known for lacking image quality, easily beaten by Sigma for half the price.
So eventually Sony confirmed the bad effects of smaller size E-mount.
Sony can't make 85mm f/1.2 lens like Cannon and Nikon. Also their best G-master lenses suffers from heavy focus breathing (and if you compensate then you won't get the actual focal length shot and quality since it crops the image/video).
Cannon is also famous for it's cripple hammer.
Nikon is the only one whose lens category have fast primes (58mm f/0.95) designed especially to have very less or no focus breathing.
