Canon is now using rectangular plastic elements in their mirrorless cameras. Glass has always had the greatest light transmission.

Amazing technology and video, but so sad to see them stuck in the 3:2 aspect ratio, regular sized sensor. I’m moving on to medium format Fuji, where more of the image circle of Canon’s great EF lenses can be used in any aspect ratio.

They should have developed a full frame, oversized, multi-aspect ratio sensor, or at least Panasonic should have. This is sad to see.
