The EOS-1Ds Mark II’s phenomenal 16.7 Megapixel full frame (36 x 24mm) CMOS sensor produces files which convert to 50MB uncompressed TIFF at 24 bit colour depth: the standard acceptable quality for leading international photo agencies and stock libraries. It features a built-in low-pass filter to eliminate false colour and moiré effects, plus an on-chip noise elimination circuit. Low (L:50) and high (H:3200) settings can be selected to extend the camera’s wide 100-1600 ISO speed range.
