Frequently Asked Questions
What effect does the Neewer center field split diopter filter create?
It produces a blur and refraction effect on both sides of the frame while keeping the center sharp, allowing you to isolate your subject with a distinctive dreamy look straight out of the camera.
Can I control the intensity and direction of the blur effect?
Yes, the filter rotates a full 360 degrees on the lens, letting you adjust both the angle and orientation of the blur effect to suit your composition.
What aperture range works best with this filter?
Neewer recommends shooting between f/2.8 and f/7.0 for optimal results. Outside this range, the blur effect may become less pronounced or introduce unwanted artifacts.
Will this filter fit lenses that are not 67mm?
It attaches directly to any 67mm lens thread. For other lens sizes, you can use a step-up or step-down adapter ring to achieve compatibility.
Does the filter degrade image sharpness in the center of the frame?
No, the K9 optical glass is highly transparent, so the center of the image retains full clarity and sharpness while only the peripheral areas are affected by the diopter blur.
