How do those of you who have used one of these lenses > measure/calculate exposures? It's because the reading will be wrong. Therefore, simply do the reading before the shift, shift the lens, and take the picture. Note that when you shift the lens you will move some parts into the picture that where not in it before and other parts you move out. Thus, you should point the camera so that the same part is measured which will be in the picture after shifting the lens. This is especially important if you use matrix metering. It sounds obvious but when you work on a tripod you might be tempted to just leave the camera as it is.
