This is an image showing how the Dual Filter System of your newer Canon models works.
This is applicable to any cam from the 400D and newer!(so, XTi,XS,XSi,T1i,T2i,T3,T3i,40D,50D,60D,7D,5DmII,etc,etc)

The front filter is the stock IR/UV Block filter.
If it stays intact after modification, why on earth would you want to spend big $$$ on a replacement filter that does the same thing???

You can install a Baader, AstroDon, Astronomik, or even a CLEAR Glass filter in place of LPF-2, and they will all perform EXACTLY alike. period.
The only purpose an LPF-2 replacement has is to keep AF calibrated. That is it.

Hope you find this useful!!And do not let ANYone tell you "you HAVE to buy the AstroDon filter because it is sooo much better"..Baader/AstroDon/Astronomik, doesnt matter. If they work just as good as a $30 Clear Glass filter, why spend 3-4x the cost??
In fact, most 'branded' filters I get come very dirty, and are impossible to get perfectly clean(the way I like my jobs to be), so I end up returning them.

Case in point, I have ~150+ clear glass mods out there, and ~300+ Baader type mods, and every single camera performs exactly like the others. for both AP and daytime!!

Cheers!
