FAQs
Can I use this filter with standard screw-in lens threads?
No, this is a 100mm square-style filter designed specifically for use with a 100mm filter holder system.
Does this filter affect autofocus performance?
Generally, it does not, but in very low light, the slight reduction in light transmission may make autofocus hunt slightly more.
How does this differ from a neutral density filter?
A circular polariser manages glare and contrast, whereas a neutral density filter is strictly used to reduce the amount of light entering the lens to allow for slower shutter speeds.
Will this filter scratch easily?
The filter is made of high-quality glass, but like all optical glass, it should be handled with care and stored securely to avoid scratches.
Can I stack this filter with other filters?
Yes, but be mindful that stacking multiple filters can lead to vignetting and a slight reduction in overall image quality.
Troubleshooting
Visible vignetting at wide angles
Ensure the filter is seated properly in the holder and check if your lens is wider than the holder supports, which may cause physical obstruction.
Image appears too dark
Circular polarisers naturally reduce light intake (stop loss). Increase your exposure time or boost your ISO setting to compensate.
Uneven polarization across the frame
This is common with ultra-wide-angle lenses; try reducing the polarization intensity or adjusting your angle relative to the sun.
Pros and Cons
Pros
- Excellent optical clarity without noticeable color cast
- Sturdy construction suitable for outdoor conditions
- Effectively eliminates distracting reflections

Cons

Setup, Compatibility & Care
To use the Kase SkyEye 100mm filter, you must first attach a compatible 100mm filter holder to your camera lens using the appropriate adapter ring. Slide the circular filter into the designated slot on the holder. Once inserted, rotate the filter to adjust the intensity of the polarization while viewing the change through your viewfinder or rear LCD.
To maintain the optical integrity of the glass, always store the filter in its protective case when not in use. Clean the surface with a high-quality microfiber cloth and a dedicated optical lens cleaner, ensuring you blow off any loose grit or sand before wiping to prevent micro-scratches on the glass surface.
