## Long description

K&F Black Diffusion 1/4 for Fujifilm X100 series is a screw-on diffusion filter made to fit the fixed-lens thread of Fujifilm X100, X100S, X100F and X100V cameras. The filter creates a mild softening effect that reduces local contrast and controls highlights while maintaining overall image detail and color fidelity. It mounts directly on the camera's lens thread to produce a subtle glow and softer skin textures without heavy loss of sharpness, offering a controlled diffusion look for portrait, street and documentary shooting.
Advantages
The filter delivers a gentle diffusion that smooths skin tones and reduces specular highlights while retaining fine detail in shadows and midtones. Its screw-on design ensures stable attachment and correct alignment with the lens. The optical construction is engineered to produce a uniform softening effect across the frame, minimizing unwanted artifacts and maintaining natural color rendering. Compact and lightweight, the filter adds diffusion without significantly changing handling or balance of the camera.
Suitable for
 Portrait photography where subtle skin softening is desired
 Street photography to create a softer, timeless look
 Documentary and environmental portraiture to control highlights
Key specifications
 Type: Screw-on diffusion filter
 Effect strength: 1/4 (mild diffusion)
 Compatibility: Designed for Fujifilm X100 series fixed lens models
 Optical effect: Softening of highlights and reduced local contrast with preserved detail
 Material: Optical-grade filter glass with metal mounting ring
 Mounting: Threaded attachment to lens front
How to use
Screw the diffusion filter onto the lens thread of your Fujifilm X100 series camera ensuring it is securely seated and correctly aligned. Compose and focus as usual; the filter works in front of the lens to modify the image formation, so focus and exposure settings remain the same as without the filter, though you may want to check highlights and adjust exposure if necessary. For portraits, position subjects so that key highlights are softened by the diffusion effect; for low-light or night street scenes, monitor how the filter interacts with point light sources to avoid excessive glow.
Usage recommendations
Use the filter when you need a subtle, film-like diffusion without heavy loss of sharpness. Avoid stacking multiple strong filters to prevent unwanted vignetting or flare. Clean the filter surface with a microfiber cloth and appropriate lens cleaner before and after use to maintain optical quality.
