I've recently obtained a Praktica EE2, (not I believe, the most reliable of the L series Prakticas), and it seems to work OK except at speeds less than aboout 1/8 sec. I'm using 3 LR44 button cells in a home made adapter, which I originally made for my LLC camera. With old batteries which didn't have enough voltage to raise the needle to the 250 check mark, only the manual speeds worked, (but the LLC light meter still worked fine, but some of these LLC meters will still work at 1.5V, which is why you can sometimes get away with an AA battery; of 3 LLC cameras I have, 2 will work at 1.5V but one doesn't). I then tried some fresh batteries and the light meter works OK and as mentioned the shutter works down to about 1/8 sec. I then thought that these button cells may not not have enough current capacity, so I checked the voltage drop when using the light meter and the voltage dropped below 4V. Is this enough voltage drop to cause the shutter to stay open below 1/8 sec? If anyone has any knowledge or experience I would like to know before I have to spend more on a new PX21 battery than the camera
