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.
