Frequently Asked Questions

Will this filter fit my lens?

This filter is compatible with any lens that has a 49mm front filter thread.

What is the X-effect?

The X-effect is a dark cross that appears when variable ND filters are rotated to their limits. This Nano-X series is engineered to eliminate this issue.

Does it cause color casting?

K&F Concept uses high-quality AGC glass to ensure neutral color balance and minimal color shift.

Can I use a lens cap with this filter?

Yes, though variable ND filters often require a slightly larger lens cap size on the front to prevent vignetting.
