These external infrared filters are perfect for adding to a full spectrum conversion or on top of another infrared conversion to get a different effect. These are high quality polished glass IR filters, each with standard front and back threads.

This is a nice filter. I have a 720nm and 950nm as well. For this one I changed my white balance and it gave the leaves a bluish tint. Playing with the white balance can give you a few different very pleasant tones. In addition when using the color grading in LR it can give you a cool result like the picture below.

I enjoy this filter.

For the money, the Kolari Filter is a good value but somewhat frustrating to research due to a lack of data from the manufacturer. I have only been able to find one very basic graph and no real specifics. The curve is very shallow and shows 90% tranmission at approximately 800nm. This is variation from traditional wratten 720nm long pass filters and other current manufacturers. Kolari does offer another 720 IR filter called the Pro series. The chart for the pro more closely matches other manufactures and traditional wratten 720nm log pass filters but the cost is 235% of the basic 720 IR filter. If you want a true longpass 720nm IR filter then I would suggest buying either the Kolari pro series or one from another brand name manufacturer for less. My results were not what I am used to seeing with Wratten 88A filters and my Hoya filters with Rollei Infared film. It is a different look, cost was only $30 but probably will not use this filter very often.
