The Urth 43mm ND8-128 Variable ND Lens Filter Plus+ is designed for photographers and videographers seeking greater control over exposure in dynamic lighting conditions. Its primary benefit is the ability to achieve shallow depth of field and motion blur effects by allowing larger apertures or slower shutter speeds without overexposure. A potential caveat is the learning curve associated with accurately dialing in specific stop values, especially in rapidly changing light.

A variable ND filter allows you to adjust the amount of light reduction (stops) continuously, offering more flexibility in changing light conditions without needing to swap out multiple fixed filters.
Use this filter when you need to reduce the amount of light entering your lens. This is particularly useful for achieving shallow depth of field in bright light or for creating motion blur effects with slower shutter speeds.
ND8-128 refers to the range of neutral density. ND8 blocks 3 stops of light (equivalent to 1/8th the light), and ND128 blocks 7 stops of light (equivalent to 1/128th the light). The filter allows you to adjust anywhere within this 3-7 stop range.
This filter uses high-quality Schott glass with nano-coatings designed to minimize color shifts. However, at the extreme ends of the stop range, some minor color casts may be observable.
Gently wipe the filter with a microfiber lens cleaning cloth. For stubborn smudges, use a small amount of lens cleaning solution on the cloth, not directly on the filter.
The 'X-effect' is a cross-polarization pattern that appears as an 'X' across the image, especially in variable ND filters. The locking rim on this Urth filter helps prevent accidental over-rotation beyond the usable range where the 'X' pattern typically manifests.
Yes, Urth offers a lifetime warranty on their ND8-128 Variable ND Lens Filter Plus+.
Ensure the filter is not rotated beyond its intended minimum or maximum range. Disengage the locking rim and readjust carefully to a point before the 'X' appears.
Verify that you are using the correct 43mm filter size for your lens. Ensure there are no cross-threads by gently turning the filter counter-clockwise until you feel it click, then turn clockwise to screw it on.
Recalibrate your understanding of the stop range. The markings are approximate; use your camera's meter or live view to confirm exposure. The extreme ends of the range might have slight color shifts.
While the ultra-slim rim minimizes this, heavy vignetting may occur on very wide-angle lenses. Try reducing the ND stop range or using a different filter if vignetting persists.
Setup: Screw the filter onto the front of your 43mm lens. Align the desired stop range using the outer rotating ring. The locking mechanism can be engaged to prevent accidental adjustments.
Compatibility: This filter is designed for 43mm lens filter threads. It is compatible with any lens featuring this thread size. Check your lens's front ring or specifications for the correct diameter.
Care: Clean the filter glass gently using a lens cleaning cloth and a lens cleaning solution. Avoid using abrasive materials. Store the filter in its protective case when not in use.
