ProMaster 77mm Variable ND - Basis
ProMaster SKU: 73004 | Helix SKU: PR730048
OVERVIEW
The ProMaster 77mm Basis VND filter reduces the amount of light entering your lens between 2 and 8 stops to help you control exposure.
Reducing light to control exposure is the job of a neutral density (ND) filter. A variable neutral density filter (VND) replaces numerous ND filters by allowing you to change the amount of light it holds back with a simple twist of its ring. A ProMaster Basis VND filter can reduce light by as little as 2 f-stops or as much as 8. And it can be adjusted to any amount in between these values.
There are good reasons to hold back light in still photography as well as videography. Some examples include:
- In still photography, a VND filter can allow your camera to use a slower shutter speed. The slower shutter speed creates blur with moving objects as a creative effect. One example is blurring water to give the impression of movement.
- In videography the camera’s shutter speed (frame rate) is often fixed, leaving the lens aperture to control exposure. But what if a large aperture is desired to achieve a shallow depth-of-field in bright conditions? A VND is used to reduce the light and thereby achieve proper exposure even with a large aperture setting.
All ProMaster Basis filters have the same size filter thread on the front and back. So, they are compatible with your lens cap, and they can be stacked with other, same-size filters.
Basis filters represent a terrific value. They are optically excellent and affordable and deliver great results!
Key Features:
- Replaces numerous single density ND filters by offering a range of 2 to 8 stops of light reduction
- Constructed with polished optical glass and multi-coated
- Hard stops at the minimum and maximum ends of the filter’s range
- An excellent filter at a value price
- Made in China

ProMaster 77mm Circular Polarizer - Basis
ProMaster SKU: 70449 | Helix SKU: PR704490
OVERVIEW
The ProMaster 77mm Basis filter can be used to remove or control reflections, improve contrast & saturation, or darken blue skies.
A CPL filter is a valuable creative tool. Its quality should complement your lens by handling light well and providing a clear, sharp image to the camera’s digital sensor of film. Polished optical glass, a special multi-coating formula, and high-grade polarizing film combine to achieve high light transmission and low light reflectivity. These features allow your lens to perform at its finest. Plus, any camera’s auto focus system works perfectly with a Basis CPL.
All ProMaster Basis filters have the same size filter thread on the front and back. So, they are compatible with your lens cap, and they can be stacked with other, same-size filters.
Why use a CPL filter?
A CPL is one of the most highly used filters in both still photography and videography, and with good reason. The effects of a polarizing filter are difficult or sometimes impossible to imitate in post-production software. These effects can be used to create beautiful compositions.
A CPL can:
- Control reflections and/or reduce glare on non-metallic surfaces. I.E. water, glass, glossy paint, etc.
- Improve color saturation and contrast.
- Deepen/darken the blue color of skies.
- Reduce the appearance of atmospheric haze when photographing distant objects and landscapes.
