Rodenstock 300mm f/9 APO-Ronar MC BT Copal 1 (42MT) 4x5 Lens Review

The Rodenstock 300mm f/9 APO-Ronar MC BT is a specialized large format lens designed for 4x5 view cameras. Mounted in a Copal 1 shutter and featuring apochromatic correction with multi-coating, it delivers sharp, color-accurate images across the frame. The 300mm focal length provides a moderate telephoto perspective for large format work, useful for landscape, architecture, and product photography where movements and precise rendering matter. At f/9, it's a compact, lightweight option compared to faster lenses in this focal length.

This particular unit is available used in excellent condition from KEH at $500, positioned as an affordable entry point into apochromatic large format glass. Rodenstock's APO-Ronar line is known for delivering professional optical quality in a relatively accessible package, making it a practical choice for photographers building out a view camera system without breaking the bank. The Copal 1 shutter is a standard, reliable mount that's easy to service and widely compatible.
