I am certain of the voltage. I measured the batteries. I even bought Surefire and Panasonic batteries to check different brands, 3v CR123a non-rechargables. The rechargeables I have are higher voltage and the mAh is half of typical Li batts. Soon I will get the grip and test with AA alkalines.

A repair person told me by email that aperture lever and/or rewind motor may be the problem.

If the grip doesn't work either, which I suspect it won't then the beauty is going back..

An e-mail to this company in Germany might be useful .

Their repair service lists the Dynax 7.

Certainly nothing to lose.

The disposable batteries for this camera are rated at 3 volt ( typically 3.2 volt if fresh ) .

Rechargeable of this size are available as 3 volt or 3.7 volt ( both a little bit more when freshly charged ) .

As the camera takes two batteries , the correct ones equal around 6.4 volt maximum , the others are up 7.6 volt combined .

Much more than is good for the camera and has reportedly killed them !

So do not put 3.7 volt rechargeable batteries in cameras .

I had also ordered a grip. I will try to see if the grip will help..I read in a forum that sometimes it did, most likely due to the more powerful batteries.

Good news is the supplier is cooperating, if nothing works I will return it. However, I am desperately trying to make it work and keep it :)



If the contacts are clean in the battery chamber and the batteries are fresh the camera should work as normal .
( read my above post )

If it doesn't it is faulty .

That's it . Send it back .

If it only works with a grip attached , the camera is faulty . Send it back .
That's all their is to it .

You bought something that is readily available at a fair price that is faulty .
Just send it back and buy one that works correctly .

The only fault with these cameras that can be considered acceptable is the "sticky back" issue that cameras from this era are prone too .
A simple job to clean with a bit of IPA .
