Hi Doug,

I think there are two different things being talked about here; one 
is cyan/red fringing due to chromatic aberration, and the other is 
cyan corners due to oblique rays of light going through the IR cut 
filters.

The former can happen with all lenses while the latter only happens 
with wideangles and gets worse the wider the angle of view of the 
lens.

Tina's instructions deal with the former and Cornerfix (or coding of 
lenses) deals with the latter.
