I just did the same test on my Canon 10D and got some disappointing results. I used EF20mm/2,8 and EF24-70mm/2,8L lenses. Autofocus at 31 cm and sharpest point is at 32-33cm. ;-( But when I focus at a newspaper on a wall everything looks very sharp. Can someone please explain this? Can I trust my camera or am I doing something wrong when testing Bosse? =============================================================== GO TO http://www.prodig.org for ~ GUIDELINES ~ un/SUBSCRIBING ~ ITEMS for SALE
