K&F Concept Nano-Xcel Series Holder Kit

The Nano-Xcel holder is designed to work with lenses down to 18mm focal length without vignetting. If you are shooting wider than 18mm, you may experience some corner darkening depending on your specific lens geometry.

This holder is specifically designed for 100mm wide square filters with a standard thickness of 2mm. It is not compatible with circular screw-on filters or filters of different widths.

Yes, the kit includes eight adapter rings ranging from 49mm to 82mm. This covers the vast majority of standard lens filter threads, so you likely won't need to purchase additional adapters for your current collection.

The holder is engineered with a dual-slot design to securely hold two filters simultaneously. While you could technically attempt to force more, it is optimized for a two-filter setup to maintain stability and prevent light leaks.

The holder is crafted from aviation-grade aluminum, making it both lightweight and highly resistant to impact. It is built to withstand the rigors of field photography, including exposure to varied weather conditions.
