Re: New Canon Camera Bodies Appear for Certification
DOH.
Yes, it might even depend on the battery level interpretation. If one wants to see steady decline of the battery level, that is the hard one.
If you´re about real "power left" indication, hell make two maps/curves for heavy load and light load (laboratory measurements using real loads), then apply few coeficients for real voltages on real piece of your accumulator (in-body calibration after few charging and discharging sessions, and even re-calibration after that, as battery capacity and current capabilities go down), and you´re done. Nothing one good engineer could not make in one or two days. With a power supply, volt meter, amper meter, a resistor (or real camera) and a logger.
You might find difficulty, uncertainty, less then ideal precision here and there, but it will always be million times more usable and precise than three to four bars.
For my previous EOS M, they did poor job already, as when I saw first bar to go dim, I knew I have only miutes left before it dies on me. With M6, it is much better, but still weak.
Gosh, it´s Canon, the leading company, right????
