The Nanlite FL-11 Fresnel Lens for Forza 60 is a glass Fresnel lens with Mini Bowens mount. This light modifier is only compatible with the Nanlite Forza 60 or de Nanlite Forza 60 bi-colour. The fresnel has a diameter of 6cm. You can control the light beam by sliding the casing forward or backward. This produces bundled lighting (spot) up to spreaded lighting (flood). The included barndoors enable further adjustments to the bundle-spreading for easier selective lighting. The fresnel weighs 0.8 kg.
