P-TTL uses matrix metering, so in theory, it should give better results when center weighted metering could be fooled. And in case of *ist, it can give priority in the matrix metering area corresponding to the focal point. Off centered subjects is one example where P-TTL should be better. Other reasons for P-TTL: multiple wireless TTL flash, high-speed sync TTL flash and flash exposure compensation. -- --Lawrence Kwan--SMS Info Service/Ringtone Convertor--PGP:finger/www-- [EMAIL PROTECTED] http://www.vex.net/~lawrence/ -Key ID:0x6D23F3C4--
