The other reason you might want to do this even if your lens has more than adequate coverage is for the same reasons you'd usually use rise/fall or shift: to control the field of view independent of the perspective. If you're shooting architecture this matters more than it would with landscapes, but even out in the wild, converging trees tend to annoy the eye, even if the viewer doesn't know why.

Thats what I meant when I said "in order to frame my shot." In a large percentage of my LF photos I point the camera in the right direction, center all the bubble levels, then fine framing adjustment is done using rise/fall/shift rather than using the tripod.

... If you're using a lens that doesn't cover 4x5 or barely covers 4x5 (like the 90mm Angulon) then there may be a benefit to adjusting the lens to center over the half frame. But for a 90mm Super Angulon, I probably wouldn't bother unless I needed to in order frame my shot. (mostly I use rise/fall/shift for final framing of the image without needing to adjust the tripod.)

A question because I rarely use extreme wide angle (for the format) lenses. On 4x5 and using 65mm to 90mm lenses -- would there be any distortions caused by the lenses that might have to be taken into consideration if using the top (or bottom) half of the projected image from the lens vs. using the center half?
