I am well aware that this lens is for close up photography yet can work well at infinity.
What is the reality like of using this lens for landscapes?
I am specifically interested to know what it is like if used at apertures wider than f22.
The image circle is quoted as being 189mm at f22 although some say Schneider are being conservative.
If the true figure is in excess of this is the extra usable?
The thing is a plasmat but I have no practical experience of them (yet)so I am not aware of how the definition drops away towards the limit of coverage.

All I can say is it's fine. If you remind me I can try and mount on the view camera to see just how big the image circle really is. I don't think I've managed to find it's limits with the B&J. A B&J press camera has quite a bit of movements for a press camera.
