ALPA Rodenstock 32mm f/4 HR Alpagon Lens, Aperture Only, SB17
For many reasons, the ALPAGON 32mm HR comes with an exceptional position in the ALPA lens portfolio. Its large 90mm image circle allows not only full adjustment ranges for perspective correction, but also offers enormous potential for the stitching of single images. Optimized for resolution and freedom from chromatic aberration, it beautifully preserves the surface texture of facades and reproduces even the most exquisite architectural details. The radially symmetric distortion can be corrected well in post-processing (for example with the ALPA Lens Corrector).
The focal length equivalent (to 35mm format cameras) is 21mm (for 54mm x 40mm sensors ) and 25mm (for 44mm x 33mm sensors).
