Canon Eos 5d Mark Iii Description
The professional-grade Canon EOS 5D Mark III is a full-frame DSLR camera launched in 2012 as a successor to the EOS 5D Mark II. Introduced on Canon's 75th birthday, the Canon EOS 5D Mark III boasts a few significant upgrades over its predecessor. The camera resolution on Canon EOS 5D Mark III has been increased to a 22.3 effective megapixels full-frame CMOS sensor and the image processor has been upgraded to DIGIC 5+ for an enhanced noise reduction and super fast speed. The maximum ISO speed on the Canon EOS 5D Mark III is ISO 25600 (50, 51200, 102400 as optional expanded settings). The autofocus system in the Canon EOS 5D Mark III is a 41 to 61-point autofocus (AF) system with 41 cross-type AF points and five dual cross-type points. Canon EOS 5D Mark III comes integrated with an EOS iTR (Intelligent Tracking and Recognition) system. The camera gets a 100% viewfinder coverage, offering 0.71 x magnification and faster continuous shooting at 6 frames per second.
Canon EOS 5D Mark III receives an increase in the metering zones with 63 zones and also gets silent, low vibration TTL shooting modes. The previous iteration didn't have the option of attaching headphones to monitor audio but the Canon EOS 5D Mark III comes with a Headphone-out for the very purpose. The Canon EOS 5D Mark III boasts a larger 3.2 inch LCD with 3:2 aspect ratio and approx. 920,000 dots resolution, allowing for native still images to be displayed covering the entire screen edge to edge rather than how it was in the previous models where the pictures had a black border on the bottom of the screen. Canon EOS 5D Mark III comes with dual card slots for CompactFlash (CF) with full UDMA support, and SD (including SDHC and SDXC cards). The eyecup on the Canon EOS 5D Mark III has been upgraded to Eyecup Eg for blocking stray light from entering the viewfinder and for more comfortable viewing. Though the Canon EOS 5D Mark III is not waterproof, it comes with an improved weather sealing that makes it resistant to water and dust. The shutter life of the Canon EOS 5D Mark III is rated at 150,000 cycles.
Along with all the important upgrades, the Canon EOS 5D Mark III came with a downside. While shooting, when the LCD panel on the Canon EOS 5D Mark III gets illuminated in pitch dark surroundings, it may have an impact on the camera's light metering. Canon issued an advisory because of this defect that any camera bodies that were sold with the issue will be fixed free of charge by Canon. Camera bodies shipped after the first week of May 2012 had this defect already rectified by Canon.
