Just a couple months old and actually used on just one recent trip prior to having my 1DsII converted. 77mm thin ring mount sells new for $190 plus shipping; I'll sell it here for $125 plus shipping. Condition is like brand new.
The beauty of using the screw on filter is that you eliminate any stray light such is the case when using a Cokin filter (I used them as well so I know). I got much better images using this than I ever did using the Cokin.
The "I-Ray" transmits over 90% of near-infrared light between 700 and 1100 nanometers while blocking almost all visible and UV light. Visit Singh-Ray for more details.
Paypal or check is acceptable however we'll have to wait till the check clears.
This is by far one of the best filters I've ever used for IR and were it not for the fact I finally converted my camera I'd be using it.
