On the FULL SPECTRUM Olympus E-PL1 Camera body (9-18mm lens) I was out shooting and trying the B+W 099 & 092 IR filters (550nm & 695nm) today. Both are very high quality glass (German) and worth every penny that they cost. I am kind of leaning towards the 550nm as my favorite so far. It gives AMAZING Faux Color images as well as great B&W conversions with good contrast. The 695 works well also, but just not as good as a 665nm filter. Here are 2 images for you to decide yourself!
The 099 550nm filter:
The 092 695nm filter:
As you can see, the 695nm filter gives a good accounting of itself and generates a very pleasing Faux Color image and a GREAT B&W image, but the 520nm filter just has more impact in the Faux world and does VERY GOOD in the B&W one as well!
