K&F Concept NANO-B Series Variable Neutral Density ND2 to ND400 Lens Filter with Circular Polarizer and Protective Cap for DSLR and Mirrorless Cameras | 67mm, 72mm, 77mm, 82mm

K&F Concept Variable ND2-400 Filter + Cleaning Cloth and Lens Cap

• -- Reduces the amount of light enter in the lens to catch the silk smooth object movements, without affecting the color.
• --Applies slow shutter speed under strong sunlight exposure.
• --Glass mounted with high-pressure press technology.
• -- Made by import AGC Japanese optical glass.
• --Ultra-slim frame helps reduce vignetting at the wide-angle lens.
• --CNC-non slips frame easily for installation and removal of the filter from the lens.

The NANO-B Series ND2-ND400 Variable ND Filter from K&F Concept provides an adjustable light reduction of 1 to 9 stops and reduces the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion. Create spectacular images of the ocean washing over rocks, waterfalls, rivers, or surfers flying across the waves.

• Neutral density can be adjusted from ND2 to ND400, which reduces the amount of light reaching the film without affecting the color.
• ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion. Create spectacular images of the ocean washing over rocks, waterfalls, rivers, or surfers flying across the waves.
• The wider outer optic helps reduce vignetting at wide angles.
• The microfiber cleaning cloth is ideal for cleaning oil, fingerprints, smudges, and dirt off eyeglasses, laptops, tablets, smartphones, and any other LCD or touchscreen.
• The front thread diameter is bigger than the back thread diameter.

Tips:

• Please DOUBLE confirm your lens size before purchase - via checking your lens thread size instead of camera model name, Your camera's lens thread size will be marked somewhere on the lens barrel. This number is always preceded by a "Ø" (diameter) symbol. Eg. Ø55mm=55mm thread size; some buyers only check their camera model instead of lens model, which may purchase wrong size

• Explanation of "X" cross issues - "X" cross on images is a common issue with wide angle lenses and variable ND filters. Physics limit the capabilities of variable ND filters on wide angle lenses. When you enter the edge of the max range, the "X" issue may appear on your image. due to the particular angle of the two polarizers when approaching max density

• 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 adjust your white balance accordingly when set the ND filter to different ranges

• When to use Auto (AWB) or Custom White Balance - If you have mixed light sources, such as tungsten light inside and some daylight from a window, then select AWB (auto white balance) and it will do a pretty good job of balancing them. You can also choose to set a custom balance. The short description of how to do that is: take a photo of something neutral (a white paper or a grey card) and tell the camera "use this as neutral" using the custom White Balance settings. Each camera is different, once again you'll need to consult your manual on how to do custom white balance

HD Optical glass

Neutral density can be adjusted from ND2 to ND400, Reduces the amount of light reaching the film without affecting the color.

Extend exposure time

Try an ND, or neutral density, filter. ND filters reduce the amount of light entering the lens. This makes it easier to achieve effects such as a shallower depth of field or blurred motion. Create spectacular images of the ocean washing over rocks, waterfalls, rivers, surfers flying across the waves.

Double Threaded

For this series, front thread diameter is bigger than the back thread diameter:

For example:

Back thread diameter (attach to lens): 67mm

Front thread diameter (attach additional filter/other accessories): 72mm
