Well, TAV is constantly changing the exposure because it keeps metering all the time - this is unlike manual exposure. Think of continuous AF as the same thing as TAV and green button HyperManual as similar to single shot AF where you focus lock and then compose/shoot.
It is just using manual exposure except it is quicker because you don't have to spin the dial and keep your eye on the match needle meter. -- Best regards, Bruce Sunday, February 7, 2010, 1:26:47 PM, you wrote: TL> Hmmmmmmmm, I see your point Bruce, but I thought that that was TL> basically what the Tav exposure mode was for?
