Dost casto se ve spojitosti cipu ve 40D hovori o "improved micro lenses", coz chapu jako cocky, soustredujici svetelne paprsky na vlastni fototranzistor bunky snimace. Dusledkem by mela byt mene vyrazna vinetace oproti starsim cipum (40D vs. 400D).

The improved microlens design likely contributes heavily to the reduced noise in images from this sensor, but it is also likely the reason for the Canon EOS 40D's slightly improved vignetting performance over the 30D. You can use the Lens Vignetting Comparison Tool to compare the 40D to the 30D.
