I use this camera for a variety of types of professional photography - weddings, newborns, children, and even births. The ISO handling is good for low light situations. Not amazing, but it works. The focusing system is amazing.

Little detail in shadows at high ISO

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...

In-camera HDR; "Silent" shooting mode; Rank photos in-camera with one to five stars; 61-point (41-cross-type-point) autofocus

Only slightly more resolution than four-year-old previous model; Starting price much higher than predecessor; Built-in mic only offers mono sound

In-camera HDR (High Dynamic Range) feature combines three shots into one image with better exposure; "Silent" shooting mode helps capture stealthy candid portraits; Rank photos in-camera with one to five stars, then carry those ratings over to Adobe Lightroom, Adobe Bridge and Apple Aperture.

When the Canon EOS 5D Mark II was announced in September 2008, just ahead of that year's Photokina trade show, it immediately attracted a flurry of attention for its 21.1-megapixel sensor and Full HD video capability.

With a camera of such pedigree, there are naturally high expectations. Find out how good it is in the What Digital Camera Canon EOS 5D Mark III review

Excellent set of features; build-quality is much better than MkII; AF system and overall performance

Expensive compared to some rivals

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.

When Canon introduced the highly anticipated 5D Mark III to the market, the photography community and many Canon fans felt underwhelmed by its specifications, especially after the big shock wave left by the Nikon D800.

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.

Excellent image quality; Improved handling; More responsive 61-point AF system; Fast six-frames per second shooting speed

Video not much improved out of camera; No non-compressed video thru HDMI; Video rolling shutter effect still visible

There is 5D Mark 4 and 6D Mark 2, but 5D Mark 3 is the best one. 5D Mark 4 is just minor update from 5Dmk3. 6Dmk2 has many features, but it can't bit 5Dmk3's outcome. I love 5Dmk3 :)

This camera in one word...WOW. Upgraded form the mark 2 as they were getting very old for shooting weddings and the first time i picked up the mark 3 it was great. Focus was the biggest difference it is far better than the Mark 2.

Reliable; Superior build quality; Easy to use
