Kenko Pro1D+ NDX3-450+C-PL filter review: too much in one

A handy variable ND and polarizing function in one, but a jack of all trades

Digital Camera World Verdict

Kenko's Pro1D+ NDX3-450+C-PL filter is convenient for enthusiast landscape and outdoor photographers who want to control their exposures but don't want to buy or carry around several filters. I found the 1.5-9-stop variable neutral density strength to be versatile, but the added polarizer seemed to muddy image quality and I noticed vignetting in some situations. This magnetic filter is a win for beginners and low budgets, but I wouldn't rely on it for creating high-end prints.

As an occasional landscape photographer, I like using filters for the odd blurry coastline but don't want to invest in professional-grade glass. As someone who's also made a point of cutting down their kit in recent years (I now use a 24-70mm lens for almost all my work), I don't want to carry multiple filters and holders around if I don't have to.

Urth ND1000 Filter Plus+

Urth ND1000 Filter Plus+
This powerful ND filter doesn't offer variable strengths but has 10-stop filtration for even longer exposures and creative effects. Our reviewer found it well-priced and well-designed and it didn't add any noticeable vignetting. 

Kase Wolverine Double Grad

Kase Wolverine Double Grad
Kase's Wolverine slide-in filter also offers two functions, but instead, it's solid and graduated neutral density – perfect for landscape work and blending skies. The filter holder is slightly slower to use than Kenko's magnetic version, but still portable.
