5.3. Setting Aperture
The aperture controls the amount of light entering the lens and affects depth of field. Rotate the aperture ring on the lens barrel to select your desired f-stop (e.g., f/2.8, f/5.6, f/16). Smaller f-numbers indicate a wider aperture and shallower depth of field.

5.6. Film Advance
After each shot, fully advance the film using the film advance lever until it stops. This winds the exposed film onto the take-up spool and cocks the shutter for the next exposure. The frame counter will indicate the number of exposures taken.
