Metz Mecablitz is a series of amateur and professional electronic flashguns. Metz also developed SCA adapters allowing their flash units to be used on different cameras and provide full facilities, such as TTL operation. Metz introduced the SCA standard adapter together with six other European firms (Osram, Agfa, Braun, Bauer, Regula and Paffrath & Kemper) at the 1982 Photokina[1].


The Metz SCA flash connectors ("System Camera Adapter") were launched in 1979 and comprises a range of adapters for different cameras. As flash units became more complex, offering TTL measurement and viewfinder status, each camera manufacturer developed their own proprietary contact system on the hotshoe. As well as the standard central flash trigger connection, other pins are provided for additional functions. Metz developed the SCA connectors to allow their flash units to be used on different cameras with full functionality.

SCA connectors have evolved through several generations, starting with the SCA 300 (1979) with cables SCA 500 for analog communication between camera and flash, and finally SCA 3000 (2000) which allowed digital communication between camera and flash.

The basic adapter is the SCA 301 which can be used on every standard hot shoe. Some adapters add extra functionality like the autofocus-aiding red light. The Metz SCA 332 RL is an example which adds an AF aid light and connects a Mecablitz flash unit of the System SCA 300 to the Minolta 7000 SLR camera. Some other flash makers offer flash units which use Metz SCA adapters, for example the electronic flashguns of Cullmann, Starblitz and Osram.

Flash units

Metz Mecablitz 32 series

Metz introduced the Mecablitz 32 CT 2 with the SCA system at the 1982 Photokina[2]. The Mecablitz 32 Z-1, 32 Z-2 and 32 MZ-3 were introduced at the 1992 Photokina, supporting both the old 300 type and new 3000 type SCA adapter[3].

Metz Mecablitz 36 series

Metz introduced the Metz Mecablitz 36 CT 2 with the SCA system at the 1982 Photokina[4].

The Metz Mecablitz 36 CT 3 is a flash for the ambitious amateur, compact and yet powerful. It was introduced at the 1984 Photokina[5]. The 36 CT 3 flash head can be set to indirect lightning positions 45°, 60°, 75° or 90° upwards, or into normal straight-forward lightning position or the same position with the close-up variations 5° or 10° downwards. The flash head can also be turned horizontally, up to 180° to the right or 90° to the left. On the flash light part is an uncoupled analog calculator to see which film-speed/aperture combination allows which distance in feet or metres. A second analog calculator is coupled to the electronic settings switch on the back. This calculator also shows different distances for wide, normal and tele lenses. And it switches the electronics to settings for apertures 11, 8, 5.6, 4 or 2.8, or to a TTL mode, or to the M mode (manual full output), or W (winder) mode. The uncoupled analog calculator can be switched from M to W mode or vice versa. Thus this uncoupled calculator supports aperture setting calculations for the manual and winder modes.

The flash belongs to the SCA 300 system. That means that its foot can be exchanged with a special foot for a certain camera's special hot shoe.

Metz Mecablitz 40 series

Metz introduced the Metz Mecablitz 40 MZ-2 at the 1992 Photokina, supporting both the old 300 type and new 3000 type SCA adapter[6].

Metz Mecablitz 45 series

More than any other flash unit, the 45 series established the reputation of Mecablitz for professional use. Powerful, reasonably compact using internal power, but also with the possibility of external power packs for extended use. Featuring a coupled computer dial / power setting, most versions with small fill in flash head, and most offering TTL exposure. Camera connection is made using a standard PC cable or SCA connector and cable to hot shoe.

The distinctive large main setting and readout dial offers six automatic settings, TTL (where applicable), M, M 1/2, M 1/4, and W (winder, low power for sequence shooting).

The main flash head may be tilted upwards and swivelled to either side.

Manufactured over several decades, the 45 CL-4 was available at least until 2012.

Mecablitz 45 versions
  • CT-1 Main flash only, no TTL
  • CT-3 Main flash only, TTL (Introduced at the 1984 Photokina[7])
  • CT-4 Main + fill in flash (Introduced with the SCA system at the 1982 Photokina[8])
  • CT-5 Main + fill in flash
  • CL-1 Main flash only
  • CL-3 Main + fill in flash
  • CL-4 Main + fill in flash

Metz Mecablitz 60 series

The most powerful flash unit offered by Metz, its size and bulk limited general appeal. Always used with an external power pack, usually a small 6V lead/acid battery as used for small motor bikes, the weight was considerable.

Mecablitz 60 versions
  • CT-1 Main flash only
  • CT-2 Main flash only
  • CT-4 Main + fill in flash
