The Rollei F:X Pro Round Soft GND8 is a premium circular graduated neutral density filter engineered for photographers who demand precision exposure control without sacrificing portability. Built from original Gorilla® Glass with a 0.9 density (3-stop) soft gradient, it effortlessly balances brightness between sky and foreground in complex lighting scenarios — all in a compact, screw-on format.
Unlike fixed rectangular GND systems, this Rollei filter features a rotatable ring that lets you fine-tune the gradient position on the rotation axis, making it perfectly adaptable to landscapes, forest scenes, and mountain terrain where the horizon is not sharply defined. The F:X Pro multi-coating delivers 99.5% reflection freedom and razor-sharp results even on cameras resolving up to 150 megapixels.
Key features
- 3-Stop Soft Gradient (GND8, 0.9 density): Smoothly reduces sky exposure by 3 stops while preserving natural foreground detail — ideal for scenes without a clearly defined horizon.
- Rotatable Gradient Ring: Adjust the transition zone on the axis of rotation directly on the lens, giving you the flexibility of a rectangular filter system in a compact round design.
- Original Gorilla® Glass Construction: Delivers legendary impact and scratch resistance, ensuring your filter survives demanding outdoor shoots.
- Diamond-Like Anti-Scratch Coating: The final hardness layer protects the glass from mechanical damage and makes cleaning — whether from grease, water, or mud — fast and effortless.
- F:X Pro Multi-Coating with 99.5% Reflection Freedom: Guarantees outstanding color neutrality, faithful rendering, and razor-sharp images up to 150 megapixels resolution.
- Extreme Temperature Resistance: Rigorously tested in scorching heat and freezing cold, this filter performs reliably in the toughest shooting environments worldwide.

Frequently asked questions
How is this round GND filter different from Rollei’s rectangular F:X Pro Soft GND8?
The rectangular filter adjusts the gradient by sliding it within a filter holder, while this round version uses a rotatable ring to shift the gradient along the axis of rotation. It offers the same 3-stop (0.9 density) soft transition but in a compact screw-on format that requires no holder system.
What types of subjects is the Rollei F:X Pro Soft GND8 round filter best suited for?
It is ideal for rugged mountain landscapes, forest areas, and any scene without a sharply defined horizon — situations where brightness varies gradually between foreground and background and a soft gradient transition produces a naturally balanced exposure.
Will this filter affect image sharpness or color accuracy on high-resolution cameras?
No. The F:X Pro coating is specifically engineered to maintain razor-sharp detail on cameras resolving up to 150 megapixels, while the 99.5% reflection freedom and premium glass ensure exceptional color neutrality and fidelity throughout.
