Gossen Lunasix F lens mount_Adaptall But if you're looking toThe Gossen Lunasix F is a good quality meter with excellent low light sensitivity and a unique exposure setting system: rather than matching a number on the display to the calculator dial, you rotate the calculator dial until the indicator is centred on the display, then read off combinations. The + 3 range on the display makes it trivial to set over or underexposure. It's neat! Requires one 9v battery.
