Remember when we first heard about the Mosaic Engineering anti-aliasing / anti-moiré filter for 5D mark II in August of 2011? What a great invention that would solve our biggest problem with HDSLR.
How good that the guys over at Mosaic Engineering have now officially started selling their filter for the 7D: The VAF-7D.
This upgrade will set you back by $325, but put you into the aliasing and moiré free realm of the mark III.
Versions for the Nikon D800, T2i/T3i and 60D are in production.
