BTW, Canon's aperture priority auto exposure mode is cutoff to a maximum of 30 seconds while the OM's, LX - as well as most of the Nikons, will leave the shutter open for just about as long as it requires to make that "correct" exposure. The OM's and LX however will continue to meter the scene and adjust exposure time appropriately - up or down, while the Nikons remember the exposure at the time the shutter is tripped and will not adjust. The Minoltas seem to vary from one model to the next but I haven't seen one go past 30 seconds. This list includes today's latest and greatest - including the none film variety . . . ;-)
