These little stops attach to the rails of a Linhof Technika camera and provide a hard stop to align the front standard at a set infinity point. This is ideal if you’re using the rangefinder, but it’s also handy if you’re not, so you don’t have to fiddle to get the lens into position. Once installed, you can easily flip them out of the way and move your lensboard anywhere you like. Requires 1.5mm flathead screwdriver for installation (not included)
