Contre l'aliasing et le moiré

Bonjour

Je ne sais pas si cette solution a déjà été évoqué ici mais dans le cas contraire :
VAF-5D2 Optical Anti-Aliasing Filter

We are pleased to offer this unique, precision optical accessory for the Canon 5D Mark II:

Optically corrects most aliasing and moiré artifacts in 5D Mark II HD video.
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.

Prix : $385 (USD)
