I think I probably just wasted my money, but if anyone can tell me different I'd really appreciate your input. I recently picked up what I thought was a bargain, a Pentax 1/21 analog spotmeter. It came with a working 9-volt (?) battery and it seems to work okay for the lower light exposures, but I don't have and can't find a 1.3 volt battery. I've searched and searched and of course have now discovered that the 1.3v battery is no longer made. Does anyone have this meter and have you found a substitute battery or work-around to the battery issue?
