Special camera adaptation
In photography, a connection system for flash units that supports camera-specific flash functions is called Special Camera Adaption ( SCA ) or Metz SCA . The SCA system was designed by Metz and Bosch with the assistance of Agfa and Philips ; By 1996 Metz had developed over 40 adapters for 230 camera models. It was originally intended to ensure manufacturer independence on both the camera side and the flash side, so that z. For example, when changing the camera, only a new SCA adapter had to be purchased, but not a new flash unit. While the system on the camera side came under constant pressure due to new, unforeseen technical developments that also required new SCA versions (see below), it was initially used by several providers from the flash manufacturer, but from the beginning of the at the latest 21st century only Metz is left.
Most camera manufacturers are also manufacturers of flash units and are therefore in direct competition with the SCA system. Rollei , for example , is an exception here, as only one SCA adapter is offered.
Modular adapter systems are also available from other manufacturers, e.g. B. from Sunpak .
The SCA connection is available in the following generations:
- SCA-100 - The first version of the SCA system was developed by Braun and was presented at Photokina in 1980. It was used in the flashes 370BVC, 410VC and VarioZoom 340SCA.
- SCA-500 - this first generation was only used with the Metz 60 CT-2 and 45 CT-5 handheld flashes, but was replaced at an early stage by the SCA-300 system. It is no longer available today.
- SCA-300 - development from 1979 , market readiness from 1982 , analog flash control
- SCA-3000 - supports digital flash controls
- SCA-3002
- SCA-3202 - e.g. B. Leica D-Lux (Typ 109)
- SCA-3502 - e.g. B. Leica M cameras
