APERTURE UNIT

Digital backs with electronic shutter (currently Rolling Shutter for Phase One IQ 3/4, Hasselblad X1D and partly H6D) are becoming increasingly available. The new Rodenstock aperture unit - with its almost round, 9-piece aperture pattern - optimally supports this shutter type. Besides, lens versions in short barrel can also be used on the ALPA 12 FPS with its built-in focal-plane shutter. Please consult the corresponding product pages for compatibility or ask your sales partner or ALPA directly.
