Issit? How much more power? Why does it take up more power? :dunno:
Getting a bit OT, but here goes:
Assuming current film SLR vs DSLR: Sensor, increased electronics, LCD screen, use of microdrives. All power-hungry items.
To be fair, film SLRs have motordrive that drain even more power. See tech note below.
In an earlier age, film SLRs also did not have fancier technologies like matrix metering (compared to old CdS meters?), AFS, VR, focus-assist lamp, illuminated displays, etc. Remember when cameras only had 2 button cells (3V and low current) in the base?
Note: To get a bit technical, it's the occasional need for higher currents at a consistent voltage that makes alkalines impractical, not so much the total capacity of the batteries, nor the average power (voltage x current) needed by the cam. An EN-EL3 is rated at 1400mAH but can last, say 1,000 to 1,500 images in a D70. NiMH AAs of around 2000mAH in an F100 lasts 20-25 rolls (< 1,000 pics). So F100 more power needed. But use AA alkalines in both and I would bet the D70 chokes much earlier.
I was once in a bookshop paying for something when an annoyed, young European woman barged up to counter and demanded a refund for the "defective" batteries she had put in her
digital point-and-shoot compact camera. She complained in heavily-accented English that her camera took 2 shots and died. The poor Mandarin-speaking staff catch-no-ball but kept trying to explain in Singlish that they cannot give a refund for opened merchandise, much less consummable items like batteries! The staff even tried to be helpful and opened ANOTHER pack of batteries to "exchange", and it also died after 2-3 test shots with flash.
What batteries did the lady try to use? The cheapest in the store:
Eveready "Heavy Duty" (the RED coloured ones!!). :bigeyes: :bsmilie: I would have stepped in to translate/mediate/advise except that she was very agitated and looked ready to hit someone. :sweat:
You make me blur liao, but you're right, electyx is more helpful than most here. How about you? :dunno:
