Sony really took it personally and with the new 50mm f/1.2 GM shows that Nikon and Leica were wrong with the “mount diameter” myth

Comparison I made based on Camerasize

Preorders:
Sony 50mm f/1.2 GM at BHphoto. Adorama. Fotokoch Germany. ParkCameras UK.

Sony just announced the new Sony 50mm f/1.2 GM. This lens was made with one sole goal in mind: To show the world that Sony can make better, smaller, lighter and cheaper lenses than the competition. And that all that mount diameter discussion is in practical term…pure BS. You can make an accurate specs comparison ar this BHphoto comparison page.
