Is that just for the Super Graphic and Super Speed Graphic? Because on my Anniversary Speed Graphic I don't have to drop the bed or do anything funky when using my 90mm lens (an SWD Fujinon 5.6), and the lens board stays out of the shot. In fact, I can't really drop the bed while using it and focusing on infinity, because the infinity focal point of that lens is right where the bed hinges, so if I try to drop the bed, I don't really have a place to secure the lens board on the rails. However, the Fujinon SWD 90/5.6 is a slightly retrofocal design with a flange focal length of 101.1mm, so it doesn't sit quite as far back as a true 90mm would. I've also heard of people using 75mm lenses with the Crown Graphics without any issue, other than having to drop the bed. I don't know if it would work on a Speed Graphic. I haven't tried. But there's still some rail left behind the bed when you drop the bed, so I wouldn't be surprised if you could. Especially since many have a flange focal length longer that 75mm. But I know that the Crown Graphics will allow you to pull the lens board closer to the film plane than the Speed Graphics will due to the lack of a focal plane shutter.
