Ultimaxx 58mm Variable ND Twisting Filter ND2-ND400

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.
