K&F Concept GND Nano-Xcel Series circular filters review

Summary

K&F Concept's Nano-Xcel Series circular GND filters provide a portable solution for balancing bright skies with darker landscapes, eliminating the need for bulky filter holders. These filters feature Japanese optical glass and advanced coatings, offering good value for money. However, their primary limitation is the fixed center gradient, which restricts horizon placement to the middle of the frame, making them less flexible than square filter systems for precise compositional control. While suitable for undulating horizons, they are not ideal for seascapes, and stacking them at wide angles can cause vignetting.

Key points

• Screw-in circular GND filters offer portability without bulky holders.
• Fixed center gradient limits horizon placement, unlike square systems.
• Features Japanese optical glass and advanced coatings for durability.
• Best suited for undulating horizons; not ideal for seascapes.
