I made a quick little test comparing the 35mm lenses I have. Below is a video comparing the breathing and colors, and attached are 100% crops to test sharpness. I'll let you make your own conclusions, but man, the corners on the Nikon are worse than I thought. If it's that bad on m43, I can't image what it must be like on a full frame.
Sort of going on a tangent, but does anyone else like the character of older cinema lenses where the corners are somewhat smeared with blur?
My Nikkor 35/1.4 is pretty sharp. It isn't as sharp as the Olly 45, but it is sharp. Only a few of my lenses are really sharp edge to edge, and for portraits I don't really want that anyway.
