Perhaps I can find this out on-line somewhere, but perhaps someone on here already knows -- and perhaps some viewers would be interested.

I have a Sunpak Auto DX 12R Ring Light which, like several other Sunpak flashes has a removable flash shoe module to fit a wide variety of cameras.

Since I use Minolta gear, I have an STD-1D module for a universal one-contact hot shoe (or cold shoe with a PC cord), an MX-1D module with two contacts for Minolta XG cameras, and an MX-2D module with three contacts for Minolta cameras with TTL flash capability including the EARLY MAXXUM cameras.

However, none of these will work with the newer MAXXUM (and early SONY) cameras that have the FOUR pin contacts. In fact, I can only get the STD-1D module to work on these cameras -- with a ISO to iISO flash adapter.

Does anyone know if Sunpak made a module for the newer MAXXUM (and early SONY) cameras that have the FOUR pin contacts???? I can get along without it, but it would be nice if they did!!!

I just discovered that they did -- the MX-1AF module. It is designed for the newer MAXXUM/SONY four contact iISO flash shoe -- and it adds focus assist, like the MAXXUM/SONY flashes.

There was one on EBAY, so I nabbed it.

I've received my Sunpak MX-1AF module for my Sunpak Auto DX 12R Ring Light. It's NEW, in the box, and plugs in fine. It has the second generation of MAXXUM flash shoes -- so called, iISO shoe -- so it won't fit on my MAXXUM 7000 or 5. I first used it on my Konica Minolta A2, and it works fine. Just what you would expect a ring flash to do -- basically no shadow. Here is a sample shot -- Aperture priority mode on camera, and Auto-TTL mode on flash.

I next tried it on my Sony a850 -- with the same settings -- and end up with a strange magenta color.

I've tried the ring flash on another a850 with the same results. I've tried it in manual exposure mode with the same result. I've tried other flashes on the a850 and the results are perfectly normal. And since I have ANOTHER 12DXR ring flash, I tried that, and got the same results.

Any ideas on what may be causing this odd phenomenon?

Perhaps the voltage of the strobe trigger is too high for your Sony. Do you have or can get access to a Wien Safe-Sync Hot Shoe Adapter?

You may be on the verge of cooking your camera!

According to the webpage Photo Strobe Trigger Voltages : https://www.botzilla.com/page/strobeVolts.html

the Sunpack 522 can have up to a 190 volt trigger current.

I've got a SAFE-SYNCH adapter but it converts an older ISO hot shoe flash (one, two, or three pin flash) for use on the newer Minolta/Sony iISO four-pin flash shoe. The SUNPAK 12R ring light flash that I have has the Minolta/Sony iISO four pin shoe, so I assume the flash will not cook the camera -- because it was designed with these iISO cameras in mind.

But it remains that the only constant is Sony camera not operating properly with this interface; it doesn't "like" something about these flashes and I'd be really leery of continuing to use them as such.

Have you looked at the Sony’s color balance settings?

BOTH a850 cameras show the same pink results whether the camera is set for AUTO or FLASH color balance -- AND both cameras work fine with any other flash.

Thanks, but the camera works fine with other flashes, and the flashes work fine with other cameras, so I'm looking for ideas on what's going on -- other than "don't use them together".
