Kase Armour Magnetic Circular Filter ND64

ND64 refers to the Neutral Density (ND) factor of the filter. ND64 reduces the amount of light entering the lens by 6 stops, effectively decreasing light intensity by a factor of 64.

Gently dust off the surface with a soft lens brush. For smudges, use a microfiber cloth lightly dampened with a lens cleaning solution. Always wipe gently.

Yes, you can stack it with other Kase magnetic filters, but stacking may increase the risk of vignetting on wider lenses and potentially reduce sharpness.

The magnetic system is designed for a secure attachment. Ensure it is properly seated on the adapter ring before starting your long exposure to prevent movement.

While an ND filter reduces light, it should not inherently affect autofocus performance in most modern cameras, especially in good light. However, in very low light conditions, autofocus might struggle due to reduced light.

The primary advantage is speed and convenience. Magnetic filters attach and detach much faster than traditional screw-on filters, saving valuable time in the field.

The Kase Armour Magnetic Circular Filter ND64 is engineered for exceptional optical clarity with minimal color cast. However, some very slight color shift is inherent in most ND filters.

Ensure the magnetic adapter ring is fully screwed onto the lens and that the filter's magnetic edge is clean and free from debris.

The ND64 filter reduces light by 6 stops. Adjust your exposure settings (aperture, shutter speed, ISO) accordingly. If shooting in very low light, a 6-stop filter might be too strong; consider a lower stop ND filter.

Ensure the anti-reflective coating is clean. If the issue persists, check if the filter is correctly seated and that no other light source is interfering. Minimal color cast is expected with high-quality ND filters.

While the anti-reflective coating minimizes this, strong direct light sources can still cause issues. Try repositioning your lens or using a lens hood. Ensure the filter and adapter are properly aligned.
