Pros & Cons

👍 Pros

  • Reduces the light entering your camera lens by 2 stops, offering essential control over exposure for various lighting situations.
  • Permits the use of wider apertures, which helps in achieving a shallow depth of field for artistic portraits with beautifully blurred backgrounds.
  • Allows for slower shutter speeds in brighter environments, enabling creative motion blur effects in moving subjects or flowing water.
  • Features an ACCU-ND coating, ensuring a truly neutral color balance in your images by preventing unwanted color shifts.
  • Equipped with a low-profile aluminium ring, designed to minimize the risk of vignetting and maintain image quality, especially with wide-angle lenses.

👎 Cons

  • A 2-stop light reduction might not be sufficient for extremely bright conditions where more aggressive ND filtering is required.
  • Requires careful calculation of exposure times to compensate for the light reduction, which may add complexity for beginners.
  • The filter is specifically 49mm in diameter, necessitating step-up or step-down rings for lenses with different thread sizes.
  • While it enables slower shutter speeds, a tripod is essential to prevent camera shake and ensure sharp images during longer exposures.
  • The low-profile design, while beneficial for avoiding vignetting, might make it slightly less convenient to grip for attachment and removal compared to thicker rings.
