The Hutech VLC-FF1 Daylight front filter arrived today. As expected, it made my camera back to normal operation as if it never had been modded before!
It clips on fits snuggly into the 40D between the body and the lense. Also, amazingly like no modded camera, all my manual and automatic dial functions such as macro, sport mode etc works perfectly without the need to use any custom white balancing.
This is a great filter and a must have if you really want to turn your modded camera back to stock for daylight use.
