Just like Sony also Canon now patented its first lenses made for Full Frame curved sensor cameras

Sony had already patented this idea years ago (SAR article here). And Canon is now following: They just patented their first lens designs made for a hypothetical future Full Frame curved sensor system.

A curved sensor would allow for a more compact design as you would not have to add a lot of glass to correct for corner issues. No more corner sharpness issues! The trade off is that of course it’s way more expensive to make such curves shaped sensors. So I have no clue when this idea will make it into a real production camera.

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.
