The ALPA release solutions consists of the one-shot trigger for digital backs with wake-up functionality, the ALPA Sync Release Mk II. No other manufacturer has risk this endeavor to present a true photographic solution for this problem. On the other hand there are solutions for triggering the ALPA 12 FPS and as cross-over and only possible due to the modular ALPA system, there are the release hand-grips for IQ digital backs.
ALPA Sync Release Mk II
The ALPA Sync solution allows one-shot operation (handheld and with cable release) with most digital backs that need a wake-up on technical cameras (Phase One/Mamiya, Hasselblad). This solution can potentially cure the pink cast sometimes produced by the Hasselblad HCV-39 back (the new CFV CMOS digital backs do not need a wake-up so far). For use with all ALPA lenses with Copal 0 shutter only except Schneider Apo-Digitar 5.6/24 mm XL. Please choose the the corresponding cable type ASC-HAS or ASC-POS.
Important: The ALPA Sync Release Mk II can be operated only with the newest type of Sync Cord with built-in electronic filter.
Supported ALPA Sync Cord part numbers: 170.800.461, 170.800.462
NOT supported ALPA Sync Cord part numbers: 170.800.400, 170.800.450, 170.800.460, 170.800.498 and 170.800.499
ALPA Electronic Shutter Handgrip Kit
Some digital backs, such as the Phase One IQ3 100/100 Trichromatic, have an electronic shutter that can be triggered externally. The ALPA handgrip for electronic shutters can be attached to any ALPA 12 camera body (without FPS, SWA, WA) via the ALPA feature connector.
The configuration allows the digital back in "electronic shutter" mode to be triggered directly from Live View mode. The ergonomic handle and the modular cable set can be used in many ways and allows the user to use lighter cameras such as the ALPA 12 TC as hand-held cameras.
The modular set is supplied with a screw-in handgrip piece that allows the cable to be used as an electronic cable release.
