Adorama has a hot deal on the Sirui NDH100-82 Filter Holder Kit — it’s now only $29.90, a 75% discount from the regular price of $120. The item is currently backordered, but you can place an order to lock in this amazing price.
This NDH100-82 Filter Holder Kit allows the use of an included circular polarizer filter with up the three other (sold separately) 100mm wide, 2mm thick filters. Included are 67, 72, or 77mm adapter rings, in addition to the natively supported 82mm. The filter holder’s pull-and-release locking pin helps to provide a reliable connection that allows the holder to be rotated 360°, enabling use of graduated neutral density and others.
Other 100mm filter holder solutions typically run $80+, so this is a great deal!
