There have been some criticism about the above chart using a 45 degree angle method. I have no idea whether those criticism were valid, and some claim that this would introduce errors and force FF or BF. Another chart http://www.geocities.jp/pen_pen_pentax/focus/ was "claimed" to be better as the focus target was vertical. I would also like to know if these test charts were better or should we use real life objects. Another word of caution is the lighting. Users have noticed variation whether you are using daylight or tungsten light. -- --Lawrence [EMAIL PROTECTED] http://www.vex.net/~lawrence -- --Tungsten T3 Enhanced DIA Keyboard----Nokia Ringtone Convertor-- -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net
