Installation Instructions
Due to varying QC standards across camera brands, even models of the same brand may have manufacturing tolerances. If the internal filter frame doesn't fit properly, please contact STC support or headquarters. Do not force installation.
Disclaimer
STC's Clip-in filters are innovative and rely on the camera's internal structure for stability. 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.
Frequently Asked Questions
Which Canon EOS R cameras is this IC filter compatible with?

Can I use this filter with the Canon Extender RF 2x?

What is the Interchangeable Clip (IC) design?
The IC series features a patented detachable inlay design that allows you to quickly swap out filters without removing the entire frame from your camera. This makes it easy to switch between ND strengths in the field.
Will mounting this filter affect my camera's autofocus?
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.

Our frames are custom designed for each model of camera and are all made from an aerospace-grade aluminum alloy that is non-magnetic and shock-absorbent. We use CNC machining to make sure the frame fits snugly. An ingenious spring clip fixes the filter in place and you can unclip it with a light touch of your finger. Each filter set comes with a magnetized screwdriver to help you swap out one filter for another.

All our filters use STC’s exclusive nanocoating technology for the best optical quality. Our Sensor Protector, Cine Mist, Neutral Density (ND), Astro (light pollution) series, IR-Pass (590nm/720nm/850nm), and UV-IR-Cut filters all carry a double-sided hydrophobic, anti-smudge and antistatic nanocoating to enhance or block transmission in all kinds of particular spectrums.
