Hi Andrew, I'm not sure I know what you are saying. I think Skip *was*
suggesting using a deeper IR filter, ones with an even lower cutoff
frequency than he used, such as the Wratten 87C or 87B. I was just
noticing they are a bit expensive - 67mm size for an E-1 lens at B&H.
Given the expense, I would like to see someone else try them first
also :-)
