vi isso no review da 20d mas nao consegui entender direito o final! nao sou muito bom de ingles!
"The EOS 20D gets an all new (not seen on any other SLR) nine point AF system which has its AF points in a diamond pattern. It's quite noticeably faster than than the EOS 10D and has better low light working range (-0.5 EV compared to 0.5 EV). Note that the center point is a 'cross type' sensor when used with lenses with a maximum aperture of F2.8 or faster. "
o q significa esse cross type? o fico fica mais rapido usando o ponto central em objetivas 2.8?
