Though we are still working on our review of the Canon 6D, Gizmodo just published their Lightning Review and besides the expected nods to the high quality of the stills, the unexpected moire issues they found in video have me frowning.
Gizmodo says that though the still quality is great, "Video, however, is another story. All signs pointed toward the 6D sharing the same great video quality of the 5D MK3. The thing that the 5D3 does so well—that no other DSLR has accomplished—is reducing moire patterns (rainbow-like bands along detailed surfaces). But the 6D fails where the 5D3 prevailed. Moire is rampant. This single failure ruins the 6D as a viable alternative to the 5D3 for professional video."
Blegh. I agree. That looks terrible. We'll keep an eye on this as we wrap up our review of Canon's new body.
