As a 5x7 shooter I'm aware that with a bag/wide angle bellows the 72xl has enough IC to cover 5x7 with room to spare. Giving an image equal to 15mm on 35mm, it seems to be the widest alternative among modern in-production lenses. My problem is that I don't have a good idea what the image would look like with respect to perspective, distortion, light fall-off, and all the rest.

Since 5x7 is just slightly wider than 6x17cm, I've looked at some photography books where the shooter used the 72xl on a 617 panoramic camera, but in each case the shooter is using other focals as well and particular images are not identified as to lens used (it's easy to guess, but I'd like to know for sure).

So, can anyone provide a link or even post such an image on this board? My druthers would be for b&w without the center filter and prior to any edge-burning or other modification. But anything produced by this lens and format combination would be helpful.

Thanks in advance for any examples (or comment).
