What it is and who it is for
The Ultimaxx 58mm Variable ND Twisting Filter is a multi-coated neutral density filter designed for digital, video and SLR cameras. It lets photographers and videographers control exposure without changing aperture or shutter speed. The built-in rotating ring adjusts density from ND2 to ND400 for flexible light reduction. It suits creators who need variable density in a single filter.
The specification that decides fit
The filter thread size is 58mm, so it only fits lenses with a matching 58mm front thread. Check your lens barrel or cap for the 58mm marking before purchase. The variable range runs from ND2 to ND400, covering roughly one to eight and two-thirds stops of light reduction. If your lens uses a different thread diameter this filter will not mount.
Thermals, noise and power draw in normal use
As a passive optical accessory the filter generates no heat, draws no power and produces no noise during operation. The multi-coated HD Japan optics maintain image clarity while reducing light transmission. There are no moving parts other than the manual rotating ring, so reliability depends only on physical handling. It adds negligible weight to the lens and requires no external power source.

Questions about this item
How does the ND2-ND400 range change exposure when the filter is mounted on a lens?
Twisting the ring adjusts density from two stops up to roughly eight and two-thirds stops, letting you cut light without changing aperture or shutter speed.
What thread standard does the 58 mm ring use and will it accept standard caps?
It uses a standard 58 mm filter thread, so any 58 mm front cap, hood or step-up ring will fit normally.
How much front clearance does the built-in rotating ring add to a 58 mm lens?
The rotating frame sits just a few millimetres proud of the threads, so it clears most lens hoods and caps without vignetting on wide angles.
