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.

Notes As each camera has margin tolerance, for DSLR Nikon APS-C system you may need to adjust the filter according to your specific camera model. See instructional video.  Astrophotography clip filters are only suitable for lenses 14mm and greater. As each manufacturer’s lens design is different, blurring around the edges may occur with some fisheye or super wide-angle lenses. This is normal. After you mount the clip filter, autofocus for you camera will automatically adjust to the change in optical axis. Please check the “Supported Camera & Len List” before purchase.
