The Vilia takes a different approach to the Smena series regarding easy exposure. You simply set the shutter speed to match as closely the ASA rating e.g. 1/125 sec if using 100asa (there are separate setting markings on the base on the shutter ring for this) You then use the aperture via a small lever under the lens to adjust for light conditions. This is coupled to a white dot under 5 weather symbol on the bottom of the viewfinder giving you a head up display.
