Iii. Image Quality Improvements; New 10.1 Megapixel Sensor - Canon EOS 1D Mark III - Digital Camera SLR User Manual

III. IMAGE QUALITY IMPROVEMENTS

Image quality improvements over the EOS-1D Mark II
• Higher resolution with 10.10 megapixels versus 8.2
• Improved gradation with 14-bit A/D conversion and DIGIC III
• ISO 3200 now within the standard ISO setting range, thanks to an improved sensor
• Noise reduction provided for high ISO speeds (C. Fn II -2-1)
• Noise prone to occur at high ISO speeds is reduced
• At low ISO speeds, noise in the shadow areas is further reduced
• Priority for highlight detail can be set (C. Fn II -3-1)
• Image detail from the grays to highlights is improved and loss of highlight detail
New 10.1 Megapixel
The EOS-1D Mark III's new, Canon-designed and
Sensor manufactured, APS-H-size, CMOS single-plate
sensor advances the state of the art in professional
DSLR sensor design. APS-H is the largest sensor
that can be imaged in one pass using cutting edge
semiconductor manufacturing technology. The
imaging area of the new CMOS sensor measures
28.1 x 18.7mm, appreciably larger than APS-C and
about the same size as the sensors in the
EOS-1D Mark II and Mark II
The lens magnification factor is 1.3x. Shadow noise at all comparable ISO speed settings
is 50% less than with the EOS-1D Mark II
(approx. 10 fps), low power consumption, and Live View shooting.
