For the Canon 5D Mark II: A solution for 1080p moiré and aliasing

December 10, 2012

by Mosaic Opto-Electronics, Inc.

This unique, precision optical accessory for the Canon 5D Mark II produces a profound correction of the 5D2’s well-known 1080p video moiré and aliasing artifacts.

The revised design of the VAF-5D2b provides the same excellent anti-aliasing performance as our original VAF-5D2.  However it incorporate our newest and most advanced optical design: for excellent performance with wide-angle lenses, and minimal focus disparity.

  • No reduction of 5D Mark II 1080p video resolution for most lenses.
  • True optical correction before video image capture – no postproduction software filters or processing.
  • Easily installed or removed in less than 20 seconds.
  • 5Dmk2 H.264 codec compresses with better quality with the VAF-5D2, because false, high-frequency, aliased image components are eliminated before compression.

Cropped Stills from Video With and Without the VAF-5D2  To give a quick, side-by-side glimpse of what the VAF-5D2 does for video, the following are small, cropped sections of 5D2 1080p video frames taken with and without the filter.  Moiré and aliasing always look much worse in video than in still images, however, so to truly grasp the effect of this filter, you really need to view the videos – these cropped stills were extracted from cinematographer Glenn Przyborski’s “Four Examples of Aliasing” Video; see our Video Resources Page for additional examples and information.

 

 

They’ve also got the same system available for the Nikon D800.  Video seen here:
