Default Pentax 645 (non AF) with 120 mm Macro and Ringflash?

Hi,
I would like to ask you guys out there if one of you is working with a
ring flash on the non-AF Pentax 645 with the 120mm macro lens - does
anything exist which works?
Looking at the information, the Pentax ringflashes seem to work only
with the 75mm lens on the Pentax 645 - so one would need to either use
the macro rings or the bellows, but how about the 120mm macro??
Any ideas? Thanks - George

I'm interested in this myself but I have the AF version. After investing
an awful lot of money in digital I'm now convinced to keep shooting my
landscapes on film using my 645N. I need to add a 120 macro and a 300
tele to complete my kit. I was so close to selling it recently, even
listed it in an auction and now I'm so pleased it never reached the reserve.

I own the Sunpak DX12R and I am not too happy with it. I feel the flash is
not strong enough. It has a guide number of 40. I have used it on my
Pentax 645N with the Sunpak PT2D
module and using Kodak ektacrome 100 film setting my 120mm lens at 1:1
macro and shooting at f16 to get good depth of field I find that the film
came back 1/2 to 1 full stop under exposed. I would recommend trying it
before dropping almost $300.00 on this setup. Let me know it any of this
helps I am going to test it some more but I think I will go back to a
dedicated flash held off camera. I have the Pentax AF500FTZ flash (guide
number 160) that I use off camera with a dedicated TTL cord and get good
results.
