The VAF-TXi does not help with 720p footage, which is a shame, because the 720p aliasing is much worse than the 1080p aliasing.
I got a VAF-TXi for my Rebel T2i/550d and it causes err 20 every time I try to use it.
Err 20 usually indicates a problem with the mirror mechanism, and this filter does hold up the mirror, but most people are apparently not having this problem.
I also discovered that old, adapted camera lenses with no electronics in them don't cause the error, but as soon as the camera detects a lens
with an electronic contact on it, it throws the error.
I talked to Mosaic Engineering about it and they said that most T2i users are using it with no problems, but some have this same problem for no apparent reason and they're trying to figure out why.
I found one or two other people on this forum who are having the same problem. Here is a link to a discussion I replied to with my observations:
