I've recently acquired a Metz 45 CT-4 hammerhead flash kit complete with NiCad and alkaline battery packs, a mains adaptor coloured gels etc. There are a number of leads , including one marked SCA 371, which I believe is the dedicated one for Pentax.
I can use it off camera with a wireless slave, but am interested in trying it with a TTL lead. One I have seen advertised is the SCA 346 2 AF which I believe is the Nikon equivalent.
Does anyone have any experience of using one of these with a Nikon DSLR? - I use a D600
