a lot of new model cameras lately have been sporting a high number of AF points 7D, 50D, 1 series all have a lot of points.....


I personally use ony the Center AF point..... am I losing some of the beneifts that the other AF points offer???


Also, it is said that the 7D or 1 series will focus fatser [assuming all use 2.8 lens or higher]...... using the the 7D or 1 series and having only CENTER AF active... will they focus slower????
