One-day sale on a 9-stop ND filter

Today only B&H has the Hoya 77mm NDx400 HMC Filter as their Deal Zone sale--priced at $44.95. That's a VERY good price for a 9-stop plus it is made by Hoya. It's only available as a 77mm, but that's the filter size for several of Nikon's better glass.

I'm pretty sure this is the same filter BackdoorHippie uses--I bought one in February 2014 after reading his recommendation. Back then the sale price was $49 so this is an even better bargain.

Looks like this is a 2-day sale until 11:59pm Eastern Time tonight.
