Another flash question

[SqueamishOssifrage]

I have a couple of Metz 32MZ-3 flash guns in very good condition, that I used with my Rollei system. However, by changing the adapter, I should be able to use them with my Minolta 7, even if it is only in TTL mode. The problem is that I do not know exactly which adapter to get, although Google would indicate the SCA 3302 would be the correct one. If so, would it be the model 6 or 7?

My Sigma gun is fine, but it unbalances the camera to the extent that I only ever use it remotely, The Metz guns are much easier to both carry and use.

Any advice gratefully received!

I'd check the voltage of them first, make sure they aren't too much for the camera body.

The Metz system works a bit like the Tamron Adaptall system, only for flash guns instead of lenses. The 3000 series flash heads have an interface only to a Metz SCA module, not to a camera. You then buy the correct SCA module to match your camera. I usually refer to the chart at B & H (which I can't find right now) but it lists most Minoltas up the the 9, and then skips to the D7 and D5, with no mention of the 7. On ebay.de I can find two versions of the 3302, 6 and 7, but I can't find out which one would be best.
