Canon 5d Mark iii 3 review

The Canon EOS 5D Mark III is the successor to the enormously popular EOS 5D Mark II. It's still a full-frame DSLR.

When the original EOS 5D was launched in October 2005, this camera represented the first affordable full-frame DSLR. Three and a half years later, the Mark II almost doubled the resolution from 12 to 21 Megapixels and became the first DSLR to video recording, a feature which saw it adopted by most independent film makers and many TV productions

Now three and a half years later in March 2012, we have the Mark III, arguably one of the most highly-anticipated DSLRs for years.

The headline specifications are a new 22.3 Megapixel full-frame sensor with 100-25600 ISO sensitivity (expandable to 102,400 ISO), 1080p video at 24, 25 or 30fps and 720p at 50 or 60fps, a 61-point AF system (with 41 cross-type sensors), 6fps continuous shooting, a viewfinder with 100% coverage, 3.2in screen with 1040k resolution, 63-zone iCFL metering, three, five or seven frame bracketing, a new three-frame HDR mode, microphone and headphone jacks.

The 5D III has two higher ISO settings available than the 5D II does, but when extended ISO 51200 and 102400 the image quality would not be cceptable for - even with noise reduction added. It's alot of noise. I think this is just for marketing purpose.

It also have twin memory card slots, one for Compact Flash and SD. The control layout has also been adjusted and the build slightly improved. So while the resolution and video specs remain similar to its predecessor, the continuous shooting speed, AF system, viewfinder, screen and build are all improved, and again there's the bonus of twin card slots.

As is often the case, many of the enhancements have filtered down from other models. The 61-point AF system, headphone jack and 3.2in screen are inherited from the flagship EOS 1D X, while the metering along with much of the control layout and build come from the EOS 7D; meanwhile the 100% viewfinder is borrowed from both models mentioned above.


This is what a lot of people wanted in the new 5d mark iii. People would like  the speed, AF, ergonomics, viewfinder coverage and increased toughness of the 7D but with a full-frame sensor. The 5D Mark III's continuous shooting speed may not quite match the 7D, but 6fps is noticeably quicker than the 3.9fps of the Mark II, while the 61-point AF system far surpasses the 9 and 19-point systems of the Mark II and 7D respectively. It's also nice to have twin memory card slots.
