Mike, I spoke to my brother. He says he does use the combo to manipulate focus planes, but more often he is using it for perspective control. Here's a couple of samples. The 4x5 camera, BTW, is a Cambo, se he calls it the Canon Cambo Combo. :-)
These first two were both taken with the combo, but the second had the focus manipulated:

In this next example they are two identical model reception desks, one dark brown, one light. They were both shot in the standard "3 point" angle, with the camera above the center line and looking down at the product.
The first one was shot with the Canon alone. The second one is that same shot with perspective correction done in Photoshop. The third one was done with the combo camera with perspective correction done by moving the lens board. The Canon only shot uses a slightly wider angle lens, which does exagerate the distortion, but it would be there with any lens because of the camera looking down on the subject.

This perspective control is also important for architectural photos. |
