I have a Heliopan 72mm Digital UV/IR filter for sale in mint condition in original packaging.
The Heliopan Digital UV/IR filter blocks both UV and IR wavelengths for improved color separation with digital photography. Per B&H:
This filter has been specially designed for digital cameras. It blocks ultra-violet radiation as well as IR rays. The result is improved color separation and reproduction with digital cameras. It is a necessity with artificial light for best digital results.
This is a very high end filter, sells new for $176.50 at B&H. I'm asking $80 plus shipping/paypal fees.
Send me a PM if interested.
Thanks!
Sheldon
