With the EOS 6D, Canon enters the market for affordable, full-frame DSLRs, taking on Nikon's on D600. As with Nikon's camera, Canon's big sensor captures enough light to take very good pictures in almost all lighting conditions, and it can take full advantage of old film SLR lenses . The 6D also includes some useful features you won't find on more expensive full-frame cameras, such as GPS and WiFi. PC Mag says the 6D offers "spectacular image quality" despite being "inexpensive for its class." TechCrunch concurs, saying the "image quality from this camera is phenomenal for the price" and adding that its WiFi connectivity is a "very useful addition." The camera does, however, have some limitations, including slightly slower autofocus and burst-modes compared to the D600, a less-than-perfect movie mode, and the lack of a popup flash, something the D600 includes. Even taking those limitations into account, TechRadar calls the 6D "an excellent choice for the enthusiast and club photographer looking for a full-frame DSLR."
