Metz 45 Cx-x

Check availablity: Adorama, eBay.

The the Metz 45-CT and 45-CL series consist of many models, some with only fixed capabilities, and some that are very modular, and can be fitted adaptors and accessories. For an overview of the full Metz 45-series, see Shutterworks.

The Metz 45 CT-4 is probably the easiest model to find on the second-hand market. If you buy one of the models with a SCA-adaptor, you also need the Metz SCA-301 adaptor (generic two-pin hot-shoe with a 2.5 mm mono-plug socket) to use this as a manual and auto flash. Use either the Metz 36-50 or Metz 36-52 mono-plug to pc cord to fire the flash from the camera's pc-socket.

Some of the models in this series feature a subflash, others do not.

The manual settings of the 45 CT-4 goes from 1/1 to 1/4. Fitted with the Mecamat 45-46 slave sensor gives the 45 CT-4 a lot more manual settings, down to 1/64.

Trigger voltage: According to an advisory issued by Metz, the 45 CT-1 units with a model number below 534000 are fitted with a high-voltage trigger circuit (with trigger voltages as high as 600 volts). A voltage this high may damage a modern camera. (All other flash units of the 45-CT and 45-CL series feature a low-voltage trigger below between 7 and 25 volts, depending upon model and SCA-adapter fitted.)

Metz is a German consumer electronics manufacturer. The company was founded in 1938. One of its best known product lines is a set of flash units branded Mecablitz.

The flash guns with the AF designation are dedicated shoe mount flashes that are built to work with a single, dedicated flash system. The flash guns with the MZ and CL designations are based upon Metz' SCA (Special Camera Adaption) system. SCA is modular, and let you tie a flash to a particular dedicated system with a suitable adaptor (typical cost USD 80 per adaptor). You may move a flash to a different system by buying the right adaptor for that system.

Some Metz flash guns have a USB-interface to let users upgrade the firmware for newer camera models.
