Thanks Gerry.
I have contacted out local Canon authorized service center, they asked me to
bring it to them.
I'll do it next week.
BTW, can the issue influence flash exposure metering also ?

Regards,
Alex Z

Yes, that means April 1999 (N=1999; 04=April). According to a previous
discussion on this list (back in September 1999), EOS 3 bodies with a code
later than ON0308 (meaning March 1999) do not have the much-discussed
underexposure problem (in other words, they have the more recent firmware
that fixes this problem).

Not necessarily. My EOS 3 bodies were underexposing, but were manufactured
more recently than April 1999. I sent them to Canon, who adjusted the
meters (and, as far as I know, did not reload the firmware). So your camera
might just need to be recalibrated.
