I was using a Pentax digital spot meter, to meter on some dark clouds. I had the ISO dial set at 50 and it gave me an EV reading of 7. I changed the ISO setting to 100, and metered quickly on the same spot just for the heck of it, and got the same EV reading. Hm... tried 200, 400, 1600, ... 6400 and all gave me the same EV reading of 7 from the same spot. My guess is that the digital wonderchip retains the last exposure value for a certain length of time before it gets erased from memory. If anyone has any other ideas, let me know. For anyone who uses this meter, try the above exercise, and see if this happens. I have had no problems with the meter, but I just noticed this quirk and thought I'd pass it along. A quick film change and a new meter reading will be incorrect, unless the meter has been off long enough for it to erase what was in its memory. Weird. - -GH
