Not so much in the rangefinder world. Leica and VC. In APC world, Fuji's 2.0 X lenses are compact and can take great images. I'm just sort of chuckling at the OP's indignation. Really, when it comes to sensors, size does matter in most instances. I'm pretty sure you can see a difference between a M 4/3; a full frame or even more so a Medium Format camera's images.
