"because of the difficulty of using leneses shorter than 75mm on them"
Lets see, you place a 35 to 65mm lens, on flat boards or on boards with a cone, into the front standard, place the front standard into the camera body (or not pull it out of the camera body, and then slide the focusing lever left to right while focusing on the GG. Of course you drop the bed all the way before focusing.
How is that difficult?
