Digital Camera World Verdict

The Kase Double Grad is an ingenious solution for photographers who want a more portable, and more affordable, set of ND grad filters. Although not ideal for super-wide lenses, on the whole these filters are great for landscape photographers. They should save you money and space compared to using several traditional grad filters.

Some new photography products seem so obvious upon launch that you wonder why they haven’t been invented before. Kase’s Wolverine Double Grad filters fit that bill. The 150x100mm rectangular filters, which have been designed for use in standard 100mm holders, feature two gradations on either end of the glass. There are currently two variations available: a 3-stop soft with 3-stop hard grad and a 3-stop reverse with a 3-stop medium. We had an early demo version of the former, but Kase says that more variations will be coming.

So what’s the deal, and why is this filter such a breakthrough? A traditional graduated filter is of course clear at one end and a neutral grey at the other, offering landscape photographers the ability to balance bright skies against dark foregrounds in-camera.
