More About the Astronomik CLS CCD Sony Alpha 7 Clip Filter

This Astronomik CLS CCD clip filter is optimally suited for astronomical use with Sony Alpha 7 series cameras under light-polluted conditions. It highlights the contrast between your target object and the background sky even further. Due to its wider transmission curve compared to UHC filters, a greater quantity of light will be transmitted by this CLS CCD filter. Stars will appear less dim. This filter has been optimized to obstruct the greatest amount of spurious light possible while, at the same time, providing the finest performance for desirable wavelengths. Does not block long-wavelength Infrared light.

By blocking the spectral lines of mercury and sodium-vapor lamps, but letting a large percentage of the visible light and H-alpha emissions pass, the CLS CCD filter will effectively block out most surrounding light pollution, which can spoil your images. The filters are optimized for use with lenses with all apertures, working at f/3 and above.

Photography with DSLR cameras without white balance shift becomes feasible even in a severely light-polluted atmosphere with the Astronomik Sony Alpha 7 Clip filter. Astronomik filters are parfocal with all other Astronomik filters and will not reduce optical performance. This filter is immune to scratching, aging, and high humidity. Astronomik filters arrive in a high-quality, long-lasting, plastic storage case.

Astronomik's exclusive Clip-Filter is fabricated from black anodized aluminum and laser-cut on ultra-modern machines. It can be inserted within seconds directly into the Sony Alpha 7 camera body. No adjustments are necessary, and all lens functions like focus, screen, and image stabilization, stay operational! Furthermore, this system also acts as an outstanding dust protector, keeping dust off your sensor during long exposures.

Astronomik Sony Alpha 7 Clip Filter System

Made from black anodized aluminum and laser-cut using ultra modern machinery, this patented Astronomik Clip-Filter can be directly inserted into the camera body of MkI, MkII, and MkIII versions of Sony Alpha 7, 7r, 7r IV, and 7s models in just seconds. No modifications are required and all lens functions such as focus, screen, and image stabilization, continue to be operational! In addition, this system also serves as a dust protector, preventing dust from accumulating on your sensor during long exposures.
