Sinar 4x5 Standard Square Bellows

The Sinar system features different bellows for every application. Virtually all of them can be employed as lens shades or groundglass viewing screens.
The 4x5 square universal bellows is standard with all Sinar 4x5 cameras. This versatile bellows can also be used with Multipurpose standards (front standards) to increase camera extension for all formats.
The 4x5 wide angle bellows is used with shorter lenses. This "Bag Bellows" lets you use full camera movements at short extensions.
To focus with lenses 65mm or shorter, you will need the Extra Wide Angle Bellows. Its thin-frame, double-bag design allows you to move the camera standards to within 1/4 inch of each other.
