These are the picture i promised yesterday. The first shows the Shen Hao with the 58 in focus, the second one with maximum rise applied. The maximu rise seems limited by the body of the camera, but a look at the gournd glass confirmed the lens ran out of coverage already. In the third I extended the bellows to show why it is flexible enough to use this lens on a flat lens board. The first 5 or 6 cm are much thinner then the rest of the bellows
That's a different bellows than was on my Shen-Hao. But I had an early production model - serial number was 3 digits, so the bellows was "traditional" in that it had the exact same pleating the entire length. Thus the requirement for using the bag bellows with wider than 90mm lenses.
