ADP-AMA adapter with Dynax 7, TTL & HSS

Hyacin wrote: Yeah good call... $60 (used 3600 HS D I found) and problem solved. If I need more than one off-camera flash I can just shoot with my A9 ... not like I'm going to be doing any serious heavy-duty portrait sessions with the Maxxum 7 (or at all for that matter). Thanks! and thanks!!

$60 for a 3600HS/D ?
That sounds expensive , even for Canada ! They sell for £15-£20 over here .
The UK £ is about a US $ , I'm not sure about the Canadian $ .
Have you had a look on ebay and click on the "sold items" filter ? This will show you what they have actually been selling for rather than just what they are being listed at .

I'd keep looking . It depends on what and how you want to use the flash for , as all the Minolta iISO hot shoed flashes are fully compatible with the Dynax 7 .

If all you wanted was TTL flash control , with the flash staying mounted on the camera , the Minolta 5200i would do the job .
No off camera flash , no HHS . Just a good sized flash that is hotshoe mounted .
Costs next to nothing .

If you want flash that works on camera or off camera wirelessly , controlled by the Dynax 7's flash with full TTL metering ,the Minolta 5400xi or 3500xi flashes will do you .
Still very cheap flashes . You might even pick up the smaller 3500xi for less than $10 .

The next model up give you Wireless TTL flash control , as above , but also add high speed synch ( HSS ) . They allow you to to fire the shutter faster than usual , 1/12000 second on the Dynax 9xi , and still have full flash coverage .
This is typically used on sunny days with fast lenses where you need a bit of fill in flash where a fast shutter speed would otherwise result in over exposure .
This flash is the Minolta 5400HS .
All the above flashes are very cheap as they only function correctly and with TTL with film cameras , they have limited use on digital .

The Minolta 3600HS/D , Minolta 5600HS/D and rebadged as the Sony HVL-F36AM & HVL-F56AM are the dearest just because they work fully with digital cameras .

If you want to experiment with TTL flash with the Dynax 7 , save your money and get the earlier models . If you want only one flash that can be used on either film or digital , get the later Minolta HS/D model or Sony version .
If you want to experiment with multiple off camera flash with the film camera only , then some of the xi flashes would be the cheap option . If you get the larger model to mount on the camera you then have the option of playing around with ratio flash control , where different flashes fire with different outputs .
