STC Optics announced the rumored 6-stop ND clip filter

A few days ago I reported that STC Optics will introduce a new in-body ND filter. The STC ND64 IR-Cut clip filter is now officially announced. The price is $80.56, shipping will start in mid-April. Additional information:


  • Mounting and removing the Clip-Filter is quick and easy.
  • Enabling use of ND filters on ultra-wide angle lenses without filter threads
  • Suitable for Nikon full frame DSLR
  • The fixed 6-stop ND clip filter is for the ND64 light density, passing through only 1.56% of the light, enabling long exposure motion blur effect under strong daylight
  • Also it can picture the vague dual image, the detail of the cloud in the sky and the peaceful reflection.
  • STC ND64 filter also fix the problem of color cast and too-heavy/thick problem of traditional ND64 filter with the technology of light spectrum SLC (Simulative Linear Calibration).
  • Using 1mm Germany Schott B270 optical glass and no-color cast coating to supply you a new experience of long-exposure photography.


  • The material is A2 stainless steel which is virtually non-magnetic and less brittle at low temperatures. Specially designed Clip-shaped structure could be pressed firmly while attaching the lens on camera body.

  • 6 months original manufacturer warranty

    The US uses the Logarithmic .3, .6, .9, 1.2, 1.5, 1.8. Each step is one stop. Tiffen filters for lenses, Lee and Roscoe filters for lights all use the easy to understand/calculate Logarithmic value.
