For the Canon 7D: A solution for 1080p moiré and aliasing.
Video Demos and Reviews
Director / Cinematographer Glenn Przyborski (Przyborski Productions, Inc.) has used the VAF-7D to produce the following video (direct link at http://vimeo.com/46975139) of the interior of a submarine with the 7D. This available-light demo nicely illustrates the performance of the VAF-7D when imaging highly-detailed subject matter at large apertures:
Director / Cinematographer Glenn Przyborski (Przyborski Productions, Inc.) has also produced this brief introductory video (direct link at http://vimeo.com/41491834) illustrating the effect of the VAF-7D on 1080p taken with the 7D:
Please view the above video at full HD 1080p resolution; as the severe effects of color aliasing and moiré are much more pronounced in video than in still images. Nevertheless, purely for convenience here, the following (downsampled) frames extracted from the video, give a concise impression of the effect of the VAF-7D:
First, a fabric lens case, as normally imaged by the 7D in 1080p - showing pronounced colored banding as a result of aliasing:
Next, the same lens case, imaged under exactly the same conditions, however using the VAF-7D - with the colored banding and moiré very successfully corrected:
Again, please see the source video of these images (http://vimeo.com/41491834) in the full native 1920x1080 resolution.
