The Canon EOS 5D Mark III as a full format camera is my Allrounder. I use the Camera in all areas of RAW photography and RAW video (with Magic Lantern). The Canon EOS 5D Mark III Digital SLR Camera performs with special optical technologies like 61-Point High Density Reticular AF and extended ISO range of 100-25600 make this it ideal for all purpose, shooting weddings in the studio, availibale Light photography, out in the field, Bird photography, Timelapse and great for still photography.
Professional-level high definition video capabilities includes a host of industry-standard recording protocols and enhanced performance that make it possible to capture beautiful cinematic movies in EOS HD quality. A 22.3 Megapixel full-frame Canon CMOS sensor, Canon DIGIC 5+ Image Processor, and shooting performance up to 6.0fps provide exceptional clarity and sharpness when capturing rapidly-unfolding scenes. Additional technological advancements include an Intelligent Viewfinder, Canon's advanced iFCL metering system, High Dynamic Range (HDR), and Multiple Exposure.
The original Canon battery grip BG-E11 on my EOS 5 d Mark III is mounted as an accessory. The BG enables the recording of a second battery and therefore a longer service life of the camera. When portrait is by the additional controls on the BG, E.g. second joystick, dial, shutter and MF button better handling possible.
For me this is a must have Part of my Camera. The weight balance in your Hands improved markedly, particularly when used on a tripod with long focal lengths.
In the battery Grip are two standard batteries are inserted which substantially extend the period of use of the camera.
