Summary: The Canon EOS 5D Mark III SLR is finally a complete and very powerful. Difficult to find a weak point. After a short period of adaptation becomes an extension of the arm of the photographer. Highly recommended, of course, to those who can afford the considerable expense to purchase, especially when combined with the equally powerful Canon EF 24-70mm 1:2.8 L II USM.
Pros: Image quality, Completeness and customizability of commands, Silent shutter mode.
Cons: Lack of a flasher incorporated, Tendency to underexposure.
Conclusion: As one of the true superstar digital SLRs retailing for a medium-high starting price, the Canon 5D Mark III deserves close scrutiny, and it's lived up to our expectations. Replete with new features, the Canon 5D Mark III's most important one is its full-frame sensor, whose resolution Canon kept to a conservative 22.3 megapixels.
Pros: Very high resolution, Great image quality, Excellent hue accuracy, Superb high ISO performance, Real-time chromatic aberration and corner shading compensation, Exceptional prints up to 30 x 40 inches, ISO 51,200 shots produce a good 4 x 6-inch print, Wider range of bracketing options, Very responsive, fast autofocus, 61 autofocus points, 41 cross-type, AF points cover more of the full-frame image area than past 5D models, Separate wide and tele AF microadjustments, 63...

Conclusion: Fast forward to the 2nd March 2012 and Canon announce the 5D Mk III. With 7 years of history behind this single unit the announcement came on the back of a 25th anniversary for Canon’s first camera in the EOS series, the film-based EOS 650. With such large shoes to fill and great expectations based on two extremely successful models before it, the Canon 5D Mk III had only one direction it could take… Let’s see if it got there..
Excerpt: The Canon 5D Mark III was announced on March 2, on the 25th anniversary of the EOS system and the first EOS SLR camera. Photography and the EOS system has come a long way since then as evidenced by Canon's line of DSLRs and while Canon wasn't the first manufacturer to incorporate video into a DSLR (that honor goes to Nikon with its D90), the 5D Mark II and its 1080p video was the first to be widely adopted by photographers who were (and are) increasingly being tasked...
Pros: Excellent photo/video quality, Excellent build quality, Advanced 61 point AF system
Cons: Best image quality from Raw (vs. JPEG), Overly aggressive noise reduction, Monaural on-board microphone
Excerpt: The 22.3-megapixel Canon EOS 5D Mark III captured some of the cleanest images I’ve seen from a DSLR when shooting in low light at high ISOs. That’s no small feat. Cameras such as the 5D Mark III’s predecessor — the 5D Mark II — and the 16.2MP Nikon D4 , are designed as low-light assassins, with large, full-frame sensors approximately the same size as a frame of 35-millimeter film.
Summary: While it's not a no-brainer upgrade over the Mark II, the Canon EOS 5D Mark III is worth the price premium if better performance and configurability matter to you.
Pros: The Canon EOS 5D Mark III offers a more streamlined shooting design, significantly updated feature set with more configurability, plus better performance over its predecessor. It maintains its excellent photo and video quality as well.
Cons: JPEG photos at low ISO sensitivities don't match the generally excellent level of quality that you can otherwise get out of this camera.
Excerpt: Canon's Mark II users have been waiting three years for the third 5D in the series, and it's been well worth the wait - the camera has been vastly improved in nearly every aspect. Read on to discover how and why it's our Editor's Choice winner.
Pros: Excellent image quality, Improved handling, More responsive 61-point AF system, Fast six-frames per second shooting speed
Cons: Video not much improved out of camera, No non-compressed video thru HDMI, Video rolling shutter effect still visible
Summary: While the MkII was more suited to specific photographic disciplines, the MkIII is a whole different ball game. Its a much more well-rounded, versatile DSLR than its predecessor. This is thanks to the boost in performance - namely the AF, while the quality feel is much more fitting for a camera of this calibre. While the resolution may remain similar to the MkII, Canon hasn't stood still.
Summary: The Canon EOS 5D Mark III makes a raft of improvements to the best-selling Mark II to become one of the most complete and well-balanced DSLRs around. While it may not sport a truly headline-grabbing specification, like the Nikon D800's 36 Megapixel resolution, Canon has upgraded just about every aspect of the Mark III to deliver a supremely confident camera the Mark II always wanted to be.
Pros: Great photo and video quality with low noise at high sensitivities., Powerful 61-point AF system with easy presets., Large viewfinder with 100% coverage and detailed 3:2 screen., 6fps continuous shooting., Good ergonomics, build quality and twin card slots.
