More About the Astronomik CLS Sony Alpha 7 Clip Filter

For astronomical use under light-polluted conditions, this Astronomik CLS Filter is suitable for use with Sony Alpha 7, 7r, 7r IV, and 7s cameras. The CLS Filter further brings out the contrast between your target object and the background. Since this filter has a wider transmission curve when compared with UHC filters, the CLS will transmit more light. Stars will appear sharper. The Astronomik CLS Filter has been enhanced to simultaneously obstruct as much artifical light as possible while providing the finest performance for preferred wavelengths. This filter will not block long-wavelength Infrared light.

Blocks the spectral lines from mercury and sodium-vapor sources such as street lamps, while permitting a large portion of desirable visible light and h-alpha emissions to pass, thereby eliminating most of the encompassing light pollution that can tarnish your images. Enhanced for use with all aperture lenses, working at f/3 and above.

With this Astronomik CLS Clip Filter, astrophotography with Sony Alpha 7 cameras is possible even with severe light pollution without shifting the white balance. All Astronomik filters are parfocal with all other Astronomik filters. There is no drop in optical performance. This filter is impervious to scratches, as well as the effects of aging and high humidity. Astronomik filters include a superior quality, long-lasting plastic storage container.

Astronomik Sony Alpha 7 Clip Filter System

Astronomik's patented Clip-Filter system has been designed from black anodized aluminum and laser-cut on up-to-date modernized machines. Within seconds, it can be introduced directly into the body of a Sony Alpha 7 models 7, 7r, and 7s in MkI, MkII, MkIII, and MkIV versions respectively. No adjustments are required and all lens functions like focus, screen, and image stabilization, remain operational! This Clip-Filter system also serves as an effective dust protector, keeping dust from collecting on the sensor during extended exposures.
