This is a small flash which can be fit to the Metz flash shoes (not included) and provide TTL flash with several of the Rollei cameras. Can be mounted on a flash bracket or articulating arm with a metz extension cable (not included). Works with the Metz 356 module for GX, FX, FW TLR, 6008 forward SLR.
This was tested working, but worth noting has some green corrosion on some of the battery contacts - as is common with the Metz flash which took alkaline batteries. May be cleaned with vinegar or other methods.
