CLS EOS -C is suitable for the following camera types: 7D Mark II, 80D / 800D, 77D / 70D / 760D / 750D / 700D 650D / 600D, 550D / 500D, 400D, 100D / 1100D / 1200D / 1300D. Note that this filter is not applicable to EF-S camera lenses.
feature:
1. Multilayer anti-reflection film
2. Non-cemented optical substrate coating
3. The electron beam gun evaporation technology using ion-assisted deposition coating technology has durability and scratch resistance, as well as stability in CWL (central wavelength), and is not affected by temperature changes.
4. The planetary rotation system provides the accuracy and uniformity of the coating, ensuring high passband transmission rate and out-of-band optical density value.
5. Ultra-thin filter, reduce vignetting by the greatest possible
6. Sandblasting for precision CNC machining of aviation metal materials
7. Carry out black anodizing treatment for matting treatment
8. Prevent reflection laser engraving without fading
9. 90% transmittance of the main nebula emission lines (ie Ha 656nm, OIII 496nm & 500nm, SII672nm and H-beta 486nm).
10. 0.1% of out-of-band transmission, especially the main emission lines of artificial light pollution (ie Na 589nm, Hg 435nm and 578nm).
11. Suitable for color CCD cameras and unmodified digital SLR cameras
12. CLS has a wider passband than UHC, so it is more popular when viewed under light to moderate light pollution.
13. The light pollution filter will not eliminate the influence of light pollution or increase the brightness of the object. In many cases, they will increase the contrast between the nebula and the night sky without brightening the nebula.
14. Warning: This filter is not designed for solar observation. Do not use this filter to look at the sun. If you fail to follow the warning, you will be blinded.
