Disclaimer

Frequently Asked Questions

Which Sony camera models is this ND clip filter compatible with?
This ND Clip Filter (A73 ver.) is compatible with Sony A7C, A7CII, A7CR, A7, A7II, A7III, A7R, A7RII, A7RIII, A7S, A7SII, and A9. For other Sony models, please see the dedicated versions for A1, A7SIII, A7R4, A7R5, A9II, FX3, A9III, FX2, A7V and A7IV / ZV-E1 on our website.

What ND stop options are available?
This filter is available in six strengths: 3-Stop (ND8), 4-Stop (ND16), 5-Stop (ND32), 6-Stop (ND64), 9-Stop (ND400), and 10-Stop (ND1000). Choose based on your shooting conditions — lower stops for mild light reduction, higher stops for long exposures in bright daylight or video with wide apertures.

What makes STC's clip filter frame different from competitors?
Unlike most competitors, STC uses non-magnetic anodized 304 (A2) stainless steel frames treated with Teflon coating to prevent scratches on your camera's internal structure — a key advantage over aluminum or magnetic frames used by other brands.

Will this filter affect autofocus performance?
After mounting the clip filter, your camera's autofocus will automatically adjust to the change in optical axis. No manual calibration is required for most supported camera models.

Will mounting this filter cause edge blurring with wide-angle lenses?
Some blurring around the edges may occur with fisheye or super wide-angle lenses due to individual lens design differences — this is normal and not a defect.

Will installation leave marks on my camera?
Minor marks from installation may occur but do not affect camera functionality or warranty. STC will not cover these marks or offer compensation. Please consider this before purchasing if reselling your camera is a concern.

Is this filter covered by a warranty?
Yes. STC offers the world's first warranty and repair service for clip-in filters. Please contact STC support for details.
