OM4Ti. Now that it has been pointed out it's obvious to me that OTF metering
_alone_ cannot give correct exposure with shutter speeds above 1/60s.
Reading the OM4Ti manual you'd never guess this though... it only mentions
OTF metering. Can anyone indicate a source for the OM4Ti that addresses this
kind of technical information?
Thanks Roger Davies
Hi Roger,
You might check our archives from about 6 months ago. We had a very
informative discussion on the incorrect exposure in "Auto" (OTF) mode at
slower shutter speeds i.e. 1/30 ,1/15, 1/8 caused from various types of film.
My findings revealed a difference of 1&1/3rd stop difference with Velvia and
about 2/3 stops with Astia.
Enough that I no longer use Auto mode at slower speeds.
Good Luck,
Buddy Walters
