What's the Verdict on the Canon 5D Mark II Optical Anti-Aliasing Filter?

09.18.11 @ 9:39AM Tags : , , , , , ,

I love the smell of fresh aliasing in the morning! Video/DSLR maven (and Man-child backer!) Philip Bloom first broke the news of the VAF-5D2 optical anti-aliasing filter for the Canon 5D Mark II, a $375 filter that promises to fix pesky moire issues on the venerable Canon DSLR. Now he’s got a full review of the filter (I have one on order, as I think it could extend the life of my 5D), which causes a negligible 1/8 stop of light loss:

Hans Steinert also did a sweater vest test, which can be downloaded here. Also click on the Vimeo title above to download Philip’s full 1080p video; finally, check out Philip’s full review for more info using the link below. I don’t use 24mm lenses a lot so I’m looking forward to the filter, though I could’ve used on two years ago! Better late than never…

  • Koo, do you recommend people hold off on buying this, though, until we see what Canon has to offer in the near future?

    • That definitely might be smart — depends on whether you’re planning on keeping the 5D Mark II around, perhaps even in a B camera capacity…

  • Why does the person in the video keep calling aliasing “moireing”. I thought moire effect was the “jello” effect of the image slanting a bit, whereas the aliasing is what aliasing is in any other digital format – the jagged edges / shimmering.

      @Peter
      As I understand it aliasing and moire are two separate things, aliasing is to do with thin straight lines becoming jagged in appearance due to line skipping, moire is the pattern of red and blue lines that “ripple” across fine repeating patterns, if you go to philips blog you should see examples of each, aliasing show by the frame grab of over head power lines for trams, moire pattern show in a frame grab of a material pattern. I hope this is correct and answers your question, both arise due to line skipping but present different problems on different objects.

  • how does it compares with the built-in antialiasing done in the gh2 for a normally lit scene ?
