Canon has quickly introduced a direct competitor to Nikon's new D600 and Sony's Alpha 99, unveiling the EOS 6D full-frame prosumer DSLR. The 6D appears to merge features from the 5D series, pairing the Digic 5+ image processor of the Mark III with a new 20.2-megapixel CMOS sensor that falls closer to the specs of the Mark II, though the new offering is priced below either of the older models.
