This is ongoing issue in all photo forums above or below water, suddenly you have extra resolution and when you look at the corners at 100% in Photoshop you discover that the image does not look as sharp as the lower resolution older model, therefore the new camera causes poor corners. In fact the corners are the same as they always were and the image will look the same if you downsample to 36 MP or whatever the resolution of the previous model was.
The actual situation is you can't take advantage of that extra resolution in the corners because the lens does not resolve that well in the corners.
Hi Chris, I am aware of some of these discussions and I am also aware of some debunking them.
We have to keep in mind, that even the old lenses available today were designed for film "resolution" A good quality film photo, still holds more data than the top line of digital full frame cameras. We know that not all lenses are made equal, but I can't recall ever hearing in the film days that soft corners were blamed on film having too much resolution power.
