Alpa introduces us to its new ALPA Marco Switar 5.6/105 mm and the new
Alpa Groove Adapter!
The Rodenstock / ALPA Macro Switar 5.6/105 mm is a high-performance lens for image scales of 1:4 to 4:1. The user can optimize the specific image scale via a ring-operated floating element which covers 1:3 to 3:1. Sharpness is only limited by diffraction. The ultra-low distortion nearly vanishes at 1:1 and beyond. The chromatic aberration is minimized and contrast performance is competitive.
The Rodenstock / ALPA Macro Switar 5.6/105 mm offers a constant image circle of 82 mm over the full range of image scales. The image circle allows movements for shift and tilt.
The lens features a 12 blade aperture (open and closed down) which offers a round aperture image. Out of focus highlights are rendered as homogeneously circular airy disks.
Due to its construction there isn’t space for a classical leaf shutter. It is used best together with the ALPA 12 FPS or any ALPA setup with a digital back capable of electronic shutter. The lens is delivered without a helical focus. Focusing is performed on a bellows or via a rigid tube system optimized for the specific image scale. ALPA is offering a V groove adapter plate for mounting the lens to any ALPA universal bellows.
