    There is a question about the lens flare in the comments to the video and Marco notes that he hasn't seen the colored flare elsewhere. To me, it looks like just lens flare from the 8-16 Sigma lens. You can see examples of the lens flare from this lens at

    One reviewer at http://www.dyxum.com/reviews/lenses/...asp?IDLens=579 even notes that:
    It is hard to get the lens to flare, but when it does you can get brightly colored dots. They are easy to edit out, but disturbing when present. I've also gotten a bit of a ring around the sun in a few photos, but flare is really well controlled.
    So its the Sigma lens.

      Ah, very good. Thank you Yuns. For a moment I thought it had something to do with the highlight issue ( pink highlights ) possibly effecting the color of the flares.

        Thank you Marco. Great job.
        BMC is a super camera and gives a super picture with unreal dynamic range. But it is possible shot with BMC some like this https://vimeo.com/50012696 from the hand?
        Sorry, for the English language.

          but in this "test" everything made especially to promote bmc and to screw up 5d. if you don't see it.. lol, i don't know how did you use your 5d then.
          I don't see any issues with the 5D video that haven't been issues with Canon DSLR video since day one. They are by their nature very limited in the kinds of shots they do well compared with any decent quality real video camera shooting a high quality 4:2:2 video codec or better.

                    I would say you just need to worry about the rolling shutter. Other than that, you can do this, especially with a tripod or other support system, like a Steadycam Merlin, or Zacuto shoulder rig.

                      Looks great, I love the titled, train shots, looks like 70s film vibe

                      • nice videos.

                        though what i'd simply like, which would put the artifacting into perspective, is just shoot someone wearing various types of pinstripe dress shirts. simple as that, have them move around a bit and see how fine the pinstripes can be for the aliasing to be noticable

                        • But that kind of question is already answered by looking at the resolution chart. It shows you exactly what you can expect, at what level of detail.

                          • yes, but that's charts, and while yes you can derive what to expect, im not about to to macys with my caliper and start measuring pinstripes, though yes i could.... ok fine hang on a second while i measure my own wardrobe....

                            ok, so i've got pants at 3.26mm and a shirt at 5.31mm between stripes

                            but then there's the thickness of the stripes which are a factor, here the pants are 2.9mm and the shirt .80mm roughly.

                            so while i can put those against the charts, it's not quite the same as looking at the actual shot and seeing if the level of artifacting is acceptable to me, or she, or whomever.

                            but yes, estimations can be made using the charts and a caliper

                            • I was waffling in the kodak thread about early kodak sensors, an image I posted..

                              I think the point is a chart can translate to a real scene..

                              And BTW your pinstripes. they are small when further away from the lens!

                              And this image we could have cured by gettng closer or further away If we had a suitable monitor to actually spot it.

                              And while we are chatting 5d3, I found it pretty soft IMO, just from a casual test, I wore a nightmare shirt!

                                Look at the chart again. You're going to see aliasing on EVERY edge, at every possible distance. Look at all the edges, at even the most widely spaced ones, and you'll see color fringing on them. It's only when they reach a certain distance and beyond that it becomes a total mess of colored stripy-ness.

                                Thing about moire patterns is that you can't necessarily predict when it will be "fine" and when it will overwhelm your shot. Because it's not just the width of the pattern that matters, but also the distance from the camera combined with the focal length of the lens. What leads to moire patterns is when the pattern of detail, as sampled by the sensor, hits a certain level of repetitiveness. If you move six inches closer, the moire pattern might totally disappear. If you move six inches further away, you might be swamped with rainbow stripes all over your image. You can't necessarily predict it.

                                So when I said "look at the chart", what I'm saying is that you will see colored aliasing on every pattern beyond a certain level of resolved detail, so if you look at the chart and see where it all goes straight to hell in a dragster-powered handbasket, you can get an idea of the fineness of detail that's going to be a problem. Then you'll have to compare that against your shooting style and your own experience of how big the patterns are on your monitor, the way you shoot.
