Canon EOS 5D Mark III field review

Shoot in the dark. That's essentially what you can do with the Canon 5D Mark III -- with a top sensitivity of ISO 102,400, what was once unfathomable could soon become an acceptable standard. While point-and-shoot manufacturers are adding WiFi and GPS, and tweaking algorithms in an effort to boost sensitivity beyond the 6400 mark, Canon and Nikon are making clear cases for a DSLR upgrade, by drastically improving image quality. The 5D Mark II had an excellent three-year run, but with its 22.3-megapixel sensor, 1.04M-dot 3.2-inch LCD, improved autofocus and high-performance video capabilities, Canon's latest full-frame DSLR is an entirely different beast, and a very compelling successor.

We spent two glorious weeks with a pre-production 5D Mark III before reluctantly shipping it back to Canon. The biggest benefit (for us, at least) has been high-ISO shooting. While the former 5D could theoretically handle ISO 25,600 captures as well, its native range topped out at 6400 -- venturing beyond that territory meant taking a hit on image quality, making it a seldom-used feature that benefited the camera's spec sheet far more than our low-light snap collection. With this latest iteration, we were able to capture sharp images in environments where there was far too little light to make out details with the naked eye, just as we have with the larger (and pricier) Nikon D3S. Our resulting scenes look like they were lit with sophisticated rigs, or in an environment that allotted far more natural light than was actually available. Low-light shooting is but one benefit of the Mark III, however, so join us past the break for a closer look in our field review.
