Thanks very much! I read somewhere that these hearing aid batteries don't last as long as 'specially made' replacement ones which are around $10 each on ebay!!!!! The zinc air with their cheap prices are tempting but will the 1.4v affect the meter?? If so how much compensation should I give it?? Also how much use do you get out of one of your batteries??
I've been studying how the meter works in the QL17 GIII, as I'm about to attempt an intentional mis-calibration in order to change the ASA/ISO range from 25-800 to 50-1600. No two people ever seem to agree on anything regarding those batteries and the meter calibration, but here's what I can tell you ...
With the "bad" off the shelf battery, the GIII agrees perfectly with the Pentax K1000 (my lab standard)
🙂 🙂 in my precision standard test box (the blank wall of the bathroom with the lights on dimmers).
🙂 Under sunny-16 daylight, the GIII reads about 1/2 stop overexposed compared to the Pentax.
Since I've always considered a meter to give you a suggestion and not a mandate for exposure, I consider them both to be quite close enough.
The true test, however, is how it performs in the real world. Both of these cameras do produce consistently well exposed shots, even with slide film (I recently ran a roll of Kodachrome in the CIII) so I would call them both good.
Our sole remaining camera shop does now sell the air cells, so I may try one of them, but my guess is that there won't really be that much difference. Some people do claim that using the wrong battery will do such things as cause your camera to self-destruct or keep the country from winning the war.
🙂 🙂
My suggestion is to pick a battery, shoot a few rolls, and check the negatives to get an idea of how the exposure is.
Sorry for such noob questions as I have only used fully manual soviet rangefinders before and have *never* played around with canon! 🙂
Hey, the only stupid question is the one that is not asked, right?
