I did test my 90mm leaf lens shutter against the camera shutter. I don't recall seing any glaring differences. This might mean my 6x7 body has a slow shutter. This would be no surprise, given the size of the thing. I don't recall ever using a view camera shutter faster than about 1/30th of a second.
