Why G2 exposes differently from 20D DSLR?

I'm new in this section of the forum. Hoping someone can enlighten me.

I recently got a light meter and did a quick test with my old G2 and my 20D DSLR. I acquired a correct exposure setting from the light meter on an average indoor scene, and set both cameras accordingly, and took the picture.

The G2 lcd and histogram revealed clear overexposure by about 1.5 stops, while the 20D acquired a perfect exposure.

I tried this several times, and each time the G2 overexposed on the light meter's suggested settings. What gives?

Perhaps it's the way the image is captured between the two cameras, but I just want to know why the G2 apparently does not expose the same way as the DSLR... and I apparently cannot use it with the light meter.

Thanks in advance.

Nothing's apparently wrong with the G2. I still take wonderful exposures with it...only it doesn't "listen" to the light meter.

I.5 stops seems Quite a lot.
my G6 works fine with my hand held meter... better than it's own readings.

Never-the-less you can always set an exposure compensation on your G2 when using your hand held meter. Or better still re-rate the Iso on the meter for the G2

This was normal practice with film cameras, so as to get the result you actually preferred, rather than that the camera suggested.

I also suspect that the reason for the difference to be the ISO rating for the G2.

I also recall reading somewhere on the forum that the ISO 50 (don't know if it was for the G2 or some other Canon model) setting actually conforms much more to something like 100 or even 200 in real film.

If you take this into account, you should be fine.

Best regards,

Yup, the G6's sensitivity rating is very conservative and it must be a trait of the G-series - it's an added bonus when shooting in low light with that fast zoom.
