EOS 5D Mark III is generated by a full-frame 22.3-megapixel CMOS sensor that can shoot up to 6 frames per second (fps). Powered by Canon's state-of-the-art DIGIC 5+ image processor, the EOS 5D MARK III is capable of incredible ISO speeds of up to 25600 (expandable to 102400). A newly expanded 61-point Auto-Focus (AF) system makes it easier to track subjects with higher levels of precision and speeds.22.3-megapixel sensor
High resolution 22.3-megapixel images of superb quality and detail are attained from Canon's cutting-edge full-frame CMOS sensor technology. New photodiode construction, gapless microlens array and on-chip noise reduction circuitry on the CMOS keep image data clean and clear even at high ISO settings and long exposures, so your photographic vision is never compromised.61-point high-density reticular AF
The EOS 5D Mark III features a next-generation Auto Focus (AF) system sporting 61 point high-density reticular AF (41 cross-type points) that offers wide, auto focus coverage at high precision as well as enhanced subject tracking capability.
It offers multi-zone wide-area AF for better tracking, has 5 central dual cross-type points (f/2.8 diagonal), 21 central cross-type points (f/5.6 horizontal & vertical) and 20 outer cross-type points (f/4.0 horizontal) and is sensitive in extremely low-light situations (EV-2 for a central point with a f/2.8 lens).
The technological advancement in the EOS 5D Mark III dramatically expands focusing accuracy to support a larger range of f/4.0 and f/5.6 lenses.ISO expandable to 102400
No matter your exposure requirements, the EOS 5D Mark III allows flexible ISO speed settings of ISO 100 – 25600 and expandable to L: ISO50, H1: 51200 and H2: 102400 to adjust the camera's sensitivity to light. From low light indoor environments to the great outdoors in broad daylight, the EOS 5D Mark III captures every picture in the best possible light.
