ALPA Silex Mk II for highly mobile use in the field and in the studio. ALPA Silex Mk II is the ultimate, individual control unit in the ALPA system. This "Swiss knife" enables direct control of lenses equipped with Sinar eShutter e125 and e250. Using ALPA ELA (Electronic Lens Adapter) Silex can also control all electronic lens modules in the ALPA system: Canon EF, Nikon E, Hasselblad H, Contax 645 and Rollei 6000 (currently no longer available).
The ALPA Silex Mk II control unit and the ALPA 12 FPS have a wide range of functions, from clever bracketing control and various shutter modes, also for digital backs with "electronic shutter", individual synchronous programs to shutter/iris and focus control. A built-in web server also allows control via a network without the need to install any software at all.
ALPA is constantly expanding the range of functions via firmware updates. The use of Sony L-Type batteries, which are available almost everywhere, also significantly reduces operating costs.
