The slide itself runs on high-precision ball bearing guide rails to avoid any play. The solution has a level of precision that is second to none. The new electronically controlled slider ALPA CASTEL-MICRO was specially developed for focus stacking in close-up and extreme macro photography, for example of insects, minerals, scientific documentation, and much more. ALPA is offering a V groove adapter plate for mounting the lens to any ALPA universal bellows. Focusing is performed on a bellows or via a rigid tube system optimized for the specific image scale. The lens is delivered without a helical focus or the like.
It is used best together with the ALPA 12 FPS or any ALPA setup with a digital back capable of electronic shutter. The lens features a 12 blade aperture (open and closed down) which offers a perfectly round aperture image for an outstanding Bokeh: out of focus highlights are rendered as homogeneously circular airy disks.ĭue to its construction there is no space for a classical leaf shutter. The image circle allows therefore movements for shift and tilt.

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 chromatic aberration is minimized and contrast performance is superior. The ultra-low distortion nearly vanishes at 1:1 and beyond. Sharpness is extraordinary and only limited by diffraction.
The user can optimize the specific image scale via a ring-operated floating element which covers 1:3 to 3:1.
The Rodenstock / ALPA Macro Switar 5.6/105 mm is a high-performance lens for image scales of 1:4 to 4:1. ALPA Macro Switar 5.6/105 mm - When Every Detail Counts
