One of the things that many people seem to have noticed about the new Nikon Z6/7 and Canon EOS R full frame mirrorless cameras is that the lens mount is huge. They look at their Sony with its relatively small E-Mount and wonder what the big deal is? Is it all just marketing hype from Nikon and Canon to sell super fast aperture lenses?
Maybe not. Leica manager Stephan Schulz backs up the idea that Sony’s E Mount wasn’t designed for full frame cameras in a recent interview with Reddotforum. He also explains why the L mount was developed to address the needs of full frame mirrorless cameras and lenses with autofocus.
