Color separation filter is not necessary the Foveon X3 sensor, and it actually works like the color separation system of our eyes. Color separation system of our eyes also has layers and our brain makes a wonderful calculation for distinguishing the colors. SD10’s new color condition algorithm and circuitry used for calculation also helped to produce a better color condition as well. The SD10 has also improved, dynamic range, color capture and increased sensitivity by utilizing a micro lens on each pixel location.

In fact, lens field angle is 1.7 times less and this fact is an advantage in tele-angle position, but disadvantage in wide angle position compared to APS sized digital camera with 1.5 times lens field angle. However, this problem is solved by wide zoom lens 12-24/4.5-5.6 EX DG Aspherical HSM and it is now possible to obtain the equivalent of 20.4mm-40.8mm field angle. Since 24mm field angle is enough in most shooting conditions, I am satisfied with 15-30/3.5-4.5 EX DG Aspherical lens. In addition, 20.4mm wide zoom lens can offset image sensor disadvantage, which is 1.7 times field angle, and satisfies me for compositional intention.
1.7 times field angle in tele-angle position is an advantage now. A 300mm compact zoom lens can be 510mm telephoto lens and 500mm lens can be 850mm lens.
