Yes, but not what you think it refers to. It is not the diagonal of the sensor area as most people would think. It is actually a confusing system dating back to the standard sizes of TV camera tube. The image circle or the diameter of the sensor area is roughly 2/3 of the tube size. > What is the aspect ratio 4/3 like a pc/tv monitor or > 3/2 like 35mm film? or something else???? Aspect ratio is 4:3; dimension approx 18mm x 13.5mm -- --Lawrence Kwan--SMS Info Service/Ringtone Convertor--PGP:finger/www-- [EMAIL PROTECTED] http://www.vex.net/~lawrence/ -Key ID:0x6D23F3C4--
