I brought the Novoflex Balpro Tilt and Shift Bellows with a Schneider Kreuznach 90mm mounted in it. It is super amazingly sharp, and a lot of fun to use. By stitching 5 vertical photos together I get large 60-70 megapixel files.
In the panoramas I use mostly the shift movement of the bellows. In this photo you can see how the tilt-movement affects the plane of focus. The olive tree in the right of the picture is in focus, and the focus plane travels through the big tree and all the way up to the mountain and then on to infinity, and beyond.
The Novoflex has a very long focus range. Can be used for macro, as well as for astro photography. In this phot I could have used a smaller f-stop to get more depth of focus. The biggest aperture on this lens is 4.5.
