Product description
- Neutral density can be adjusted from 2 to 8 stops, easy to create different neutral density by rotating the ring
- The front diameter is larger than the back diameter of this filter , which is specially designed to avoid vignetting at wide angle lens
- Allows the use of slow shutter speeds, with high speed films or digital cameras, to record movement/image blur in subjects
- Decrease the depth of field by using wider apertures, which helps separate subjects from their background
- Suitable for dynamic screen, waterfalls, streams, clouds, cars, waves or any fast moving subject
Introduction:
By rotating the front ring you are able to control the amount of light (between +1 and +8 stop values) that enters the lens.
For example, f/4 instead of f/8 for selective sharpness instead of great depth of field, or 1/15s instead of 1/60s for a smooth, blurred water effect instead of a 'frozen' waterfall.
Explanation of "X" spot -"X" spot on images is a common issue with all variable ND filters when used at max range.
Physics limit the capabilities of variable ND filters on wide angle lenses. When you enter the edge of the max range, the "X" dark spot may appear on your image. Because you are using it beyond its capability according to the laws of optical physics, which will inevitably cause this phenomenon.
If you want to use ND filter at wider angles, we suggest you to use a ND1000 filter.
Lens cap or lens hood may not fit this filter
The front diameter is larger than the back diameter, which is our special design to help reduce the possibility of vignetting (the darkening of corners) at wide angle.
If you still want to mount lens cap, you will need to take the filter off or use a lager thread cap instead. eg, if you have a 58mm lens, you need a 62mm lens cap.
Color Shift
The color of the image may vary between warm and cold. This is a common phenomenon of all variable ND filters. You need to asjust your white balance accordingly when set the ND filter to different ranges.
