The Regula Sprinty BC 300 is equipped with a Rectamat shutter system, which links apertures (f2.8; f4; f5.6; f8; f11; f16) and shutter speeds (1/30; 1/60; 1/125; 1/300) in an EVs program, allowing specific combinations:

• 1/30 and f2.8
• 1/60 and f2.8, f4, or f5.6
• 1/125 and f5.6, f8, or f11
• 1/300 and f11 or f16
• Bulb mode with any aperture.

The top plate also includes the shutter release button with a cable release thread, a flash hot shoe with electronic or bulb flash options, and a rewind lever. The bottom plate houses the shot counter, which resets automatically when the back cover is opened, the button to unlock film rewind and the standard tripod thread.
