ring flash for Pentax 645 nii

really trying to get my hands on a af160fc but if can't do so soon I need to find something else that will work TTL with the 645 nii

does anyone know a 3rd party unit that would work?

Does the sigma em-140 work with this body? TTL?

There is the Vivitar 6000AF available secondhand which is TTL only. It comes in different flavours so make sure you are looking at the Pentax version before buying.

Other options include daisy-chaining multiple AF-500FTZs to provide a quasi-distributed light source, and trying the "round flash," a type of ring flash soft light. For the latter, the MF lenses are kinda tight in the unit, but can be managed. : RoundFlash Universal Collapsible Magnetic Ring Flash Diffuser 45cm for Macro & Portrait Shooting ?tag=pentaxforums-20& : Electronics

I've used a Sunpak Auto DX-8R with a Pentax TTL module, in Pentax TTL mode on my 645n, works great. It has a 2.7V trigger voltage, so safe to use on digital cameras as well. I've used in on my K-70, though there I have to use it on manual or in auto mode (it has a built in light sensor).
