Pros and cons
Pros
- One filter combines neutral-density, diffusion and polarising effects, reducing the need to swap among these filter types.
- A rotating adjustment ring is designed to set ND strength, with a self-locking feature intended to prevent accidental changes.
- Customers report a close fit to the lens and appreciate the filter's quality.
Cons
- The integrated ND range is limited to ND2-32, which the listing equates to 1–5 stops of light reduction.
- It requires a 62mm lens thread and a 67mm lens cap, which may mean replacing a standard cap.

What to know before buying
Listing details to confirm
Listing details are inconsistent about the filter's series and package: the title and set name specify a three-piece set, while the built-in media list says one lens filter and three cleaning cloths. The detailed listing also calls its 62mm thread dimension a screen size, and its stated 5 x filter factor does not match the described 1–5-stop range. Confirm the selected listing and intended details before purchase.
Who is it for?
A good fit for
- Video makers and photographers with a 62mm-thread lens who want ND adjustment, diffusion and polarisation in one filter.
- Buyers seeking a soft diffusion effect alongside control of light and reflections.
Less suited to
- Users who need a neutral-density range beyond ND2-32 or light reduction beyond the stated 1–5 stops.
- Anyone whose lens does not have a 62mm filter thread, or who needs a standard 62mm cap to fit over the filter.

Customer feedback reports positive impressions of quality, close fit and value, while experiences with image quality and polarisation are mixed. Some describe a pleasing soft look, while others report blurry images. That difference matters if you need predictable sharpness, and the polarising effect may not satisfy every user. The generally favourable aggregate ratings do not resolve those specific concerns.
Positive themes
- Customers report good perceived quality and a flush fit to the lens.
- Customers describe the product as good value.
Mixed feedback
- Image quality feedback varies, from praise for a soft look to reports of consistently blurry images.
- Feedback on the polarising effect is mixed.
