PolarPro Peter McKinnon Variable ND II Review (2027)
In-depth review of the PolarPro Peter McKinnon Variable ND II: hard stops, colour neutrality, editions and the Defender protection system.

PolarPro Peter McKinnon Variable ND II
The premium variable ND with hard stops and a defender lens cap system.
Our verdict
The VND II earns its professional default status the boring way: it does not surprise you. Stops land where the markings promise, colour stays put through the working range, and the hard stops make the classic variable ND accidents physically impossible. If video pays your bills, the premium over budget variables is the cheapest insurance in your bag.
What we like
- Hard stops at each density end the guesswork and prevent X-cross over-rotation
- Two editions split the range: 2 to 5 stops and 6 to 9 stops for precision
- Excellent colour neutrality for a variable design, with minimal shift
- Defender360 case and cap system protects the glass in working kits
What to watch out for
- Premium price, and you need the correct edition for your stop range
- Larger front diameter complicates stacking and hood use
- Still a variable ND: ultra-wide lenses need care at maximum density
What owners report: PolarPro Peter McKinnon Variable ND II
Synthesized from recurring themes in long-term owner feedback.
Most praised
- Hard stops at each end of the rotation end accidental over-rotation into the cross pattern during a take
- Owners shooting skin tones praise how little colour correction the footage needs afterward
- The protective case and cap system keeps an expensive filter safe in a working camera bag
Common complaints
- Creators need the correct edition for their light, so many end up owning both ranges
- The larger front diameter complicates stacking and using some lens hoods
- Ultra-wide lenses still need care near maximum density
Who it is for
Professional and serious enthusiast videographers shooting mirrorless in uncontrolled daylight who need repeatable exposure control.
Stops and editions
Splitting the range into 2 to 5 and 6 to 9 stop editions is an optical honesty decision: a narrower span per filter means each density stays cleaner. The hard stops at both ends click home positively, so a practiced shooter sets ND by feel and trusts the frame. Repeatability across shoot days is the feature clients never see and editors always feel.
Colour and sharpness
Through its marked range the VND II holds the most neutral colour of the high-volume variable NDs, with skin tones surviving at maximum marked density without the green rescue grade budget filters demand. Sharpness on telephoto lenses holds up respectably, the traditional variable ND weakness largely engineered away at these prices.
Handling and protection
The Defender360 system, a combined case and cap approach, acknowledges that working filters live in jacket pockets and camera bag tops, not velvet drawers. The larger front element aids wide lenses but check your hood strategy: many shooters run the filter with a step-up ring and a larger cap as their permanent lens face.

Questions, answered
Which edition should I buy first?
The 2 to 5 stop edition covers the majority of daylight video. Add the 6 to 9 edition when midday, snow, beach or desert work regularly defeats the lighter filter.
Does it work for stills too?
Yes, for bright-light wide-aperture stills within its range. For long-exposure landscapes, fixed filters like the QuartzLine ND1000 remain the purer tool.
Is the mist edition worth it?
Only if diffusion is your house look. Clean-glass shooters should buy the standard edition and add diffusion deliberately per project.
