Historical / DiscontinuedCanon VAF Filters
Removable optical anti-aliasing filters developed for selected Canon EOS DSLR cameras and HD or RAW video recording systems.
CANON VAF PRODUCT FAMILY
Optical Correction Before Image Capture
Mosaic Engineering's Canon VAF-series filters were developed to reduce moiré, aliasing, false detail, and other sampling artifacts produced by several generations of Canon DSLR video systems.
The removable filters operated in the optical path ahead of the image sensor, addressing problematic spatial frequencies before image capture and video compression rather than attempting to correct artifacts in post-production.

Two Historical Installation Methods
The Canon VAF family used two related installation systems. The consolidated installation page preserves both procedures.
OPTICAL PERFORMANCE
Reducing Moiré at the Source
The VAF series provided optical anti-aliasing before digital sampling and video compression.
- Reduced video moiré and false detail
- Optical correction before image capture
- No computational processing delay
- Removable camera-specific design
- Designed around the useful resolution of the targeted video mode
CAMERA INTEGRATION
Why the Filters Were Camera-Specific
Sensor Sampling
Different sensors and video readout modes created different spatial-sampling requirements.
Mechanical Geometry
Mirror clearance, sensor position, camera-body dimensions, and mounting geometry varied between models.
Optical Thickness
Material placed in the converging image path could influence optical path length and focus behavior.
Lens Behavior
Lens angle, focal length, aperture, and zoom behavior could influence the performance of the complete camera/filter system.
