Hi Fernando and all,
From: Fernando Gonzalez Gentile <fgnzalez@xxxxxxxxxxxxx>

Unfortunately, the manual, as in every other camera on planet Earth, just
specifies metering performance... at ISO/ASA 100 :-(

Yes. I've got more data from mine:
-From ISO/ASA 6 to 250 (including the "usual" 100) it always does exactly
three minutes -- well beyond the quoted minimum.
-At ISO/ASA 320, it only does about 11-12 seconds :-(
-From 400 to 1600, maximum exposure time gets lower as usual: 8" @ 400 down
to 2" @ 1600 -- still a good performer against almost any other SLR.
-Beyond 1600, the decreasing rate is faster: about 1.5 seconds @ ASA 2000, 1
sec @ 2500 and the dreaded half-second @ 3200 :-(
But for extreme low light metering I already own a nice 2n... The real
benefit from the OM-4 series is the multi-spot metering, and this 4Ti still
performs better than my old plain 4.
Cheers,
