Canon EOS 6D Serious Moire Issue (Gizmodo Review)

Gizmodo published their short review of the Canon EOS 6D (price & specs). They praise the excellent image quality, low light performance, and all the rest of the goods that you get with Canon’s entry level full frame DSLR. But…there is a big “but”: video performance of the EOS 6D is not au pair with the quality of still images. The 6D can not hold up to the outstanding video capabilities of its bigger brother, the EOS 5D Mark III (price & specs). The problem are serious moire issues, clearly visible in the crops in the video above. Gizmodo writes:

In comparing still image quality, we found the 6D to produce nearly identical results as the 5D Mark III—that is to say, beautiful. You will not be disappointed with this camera’s terrific abilities to produce low-noise pictures at high ISOs. Sharpness is great, only slightly exceeded by Nikon’s D800 or D600.

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.

The moire issues of the EOS 6D have already been discussed over the net, if future reviews will replicate and confirm the problem it would be a pity for an otherwise so awesome EOS 6D, which, btw, produces less sensor noise than the EOS 5D Mark III.

    You are SURPRISED that the 6D falls short of the 5DMk3 is some areas – like video maybe??? Why would Canon want you to buy a 6D if they can sell you a 5DMk3 to do all the hot shot stuff like super video???

    I would like to see Canon investigate the issue since video is key feature.

    I would like to see Canon investigate the issue since video is key feature. Perhaps a firmware update could improve video processing.

    Highly doubt firmware would fix the 6D’s line skipping flaws, wish it would though since I was in the market for one. I feel thats hardware and sensor readout related, MKIII has a little magic sauce and a couple AA filters to boot. And the result is a softened image. Only dslr that has done it right is the GH2 when it comes to overall image quality.

    Good thing i decided to return it i didnt even open the box and went for the 5d markiii, i had enough bye bye moire ..

    I dislike Gizmodo reviews, I find they never get to the real story and just end up fueling hype. Yes we all know and expected the 6D to lack the video quality of the 5D3 (which many have complained is too soft anyway). The real question people need is; how is the 6D vs a 5D2 or 7D? Should I upgrade to it for video? Is the 6D video noticeably sharper than the 5D3? What is causing these issues (did canon add to the sensor like in the t4i or is it the IPB and Intra codecs exposing more detail and morie)? and could one of those drop in mosaic engineering sensor filters help the 6D like it helped the 5D2 and 7D? That video looked very bad, worse than I have ever seen on my 7D or 5D2 so my question is; is that really “real-world” performance or were setting selected to exacerbate the same issues we’ve become used to and learned to minimize look worse? (ie sharpness and shutter set to max)

      Finally someone intelligent to read. Please start a review site, I will definitely read you!

      Points like these never get raised in a hit driven cyberspace.

    I wonder what is wrong with a Canon recently. No proper mirrorless development, entry level full frame competition they came is quite late move compared to Nikon d600. It is also more expensive than d600 and now this video issue.

  • Januwe

    overpriced camera and now this crap.

    canon should lower the price to D600 levels.

    i mean who in his right mind would buy this camera for 500$ more then the D600???

    • AG

      Uhh, people with Canon lenses and I would pay $500 for Made in Japan so that oil/dust doesn’t mess up pictures.

  • Dan

    When I reviewed the 6D and put it against the 5D mark III, I noticed that the 6D was considerably sharper. I didn’t see the moire issue but then again I was not shooting brick walls. There could be a filter that Canon removed on the 6D to make it sharper that has led to this issue. Take a look at the video results:

  • DW

    The LearningCameras review also showed a much sharper video for the 6D when they put it against the 5D3. Whatever Canon removed seems to have made it sharper but added back the Moire

  • Felipe Curvello Anciaes

    If there is anyone over there thinking of a throwing a 6D away just because of this, I can send him/her my garbage can address. Tks.

  • AG

    Speaking as lay person – both the 5D3 and 6D video looks the same to me. If it’s a real issue, then I’m sure Canon will work on it. No big deal.

    Still think Canon should added an articulating screen, which is nice for video on the go.

  • Seb

    i seen many videos of the 6d with moire allready

    and i seen it to many times on payed jobs shirts cars hair ??
    but if you plan on shooting bananas i guess it will fill the job well

  • There is a relationship between moire and sharpness. Articles that praise the 6D sharpness over the mk3, while chastising the moire issues, seem to be failing to understand the trade-off that is likely occurring.

    I have not seen post-processing of 6D footage to compensate for the moire, but I’m willing to bet that the images will start to look like the mk3 images… less moire & softer focus.

    Anyone seen a good article or discussion of this somewhere???
