Camera sensors already have IR filters.

But those filters remove almost all IR light. The BW 092 does the opposite - it removes almost all non-IR light - and you need one for IR photography.

The funny thing is that the IR blockers on different cameras have different intensities.  For example, on my Fuji HS50, it's a fairly weak one (8.7 stop light penalty for IR, 11 stop light penalty for UV) which allows you to do handheld IR in bright sunlight at ISO 100, even at the long end of the zoom (1000mm EFL!)  I was wondering if the Olympus is like that too, I guess testing it will show it one way or the other  Most modern cams are not as sensitive, my nonFuji cams give me more like an 11-13 stop penalty for IR and a 17 stop penalty for UV!
