Here is a Metz mecablitz 44 MZ-2 camera flash unit in excellent condition, including the box, instructions, protective bag and diffuser. It has the interchangeable SCA camera mount foot attached, which means that it can be replaced with a foot from the Metz SCA range to fit many different makes of camera.  More information on this can be found below:

It's been a great flash unit for me, mostly used with Pentax film and digital SLR cameras with the SCA 3702 Pentax adapter, although only lightly and not very often over the years I've owned it! I'm slimming down my Pentax kit so here it is for sale.

Thanks for looking!
