Haida Rücklinsen Filter Kit Sigma 14-24 und 12-24 Canon EF Mount

Rear lens filter for Sigma 14-24mm F2.8 DG HSM and Sigma 12-24mm F4.0 DG HSM. A rear lens filter is a neutral density (ND) filter that is directly inserted into the lens mount. This has two advantages: first, ND filters are relatively small and do not require much space; second, such ND filters are significantly cheaper than a filter holder system that is mounted in front of the lens. For ultra-wide-angle lenses with a prominent front lens or a fixed lens hood, filters with a width of 150 mm are required, and such filter holder systems are expensive and bulky for transport. Therefore, rear lens filters are a good choice for long exposures in landscape or architectural photography. The filters included in the set ND 0.9, ND 1.2, ND 1.8, and ND 3.0 reduce exposure by 3, 4, 6, and 10 stops, respectively. The filters are made of optical glass, ensuring clarity and color fidelity. To avoid internal ghosting and reflections, each glass surface is coated with 10 layers of anti-reflective coating, which better protects the filter substrate and helps keep it clean for a longer period. The nano-coating of these neutral density filters provides an additional layer that enhances the water and oil repellency effect when their surfaces come into contact with liquids, allowing for more efficient cleaning. A plastic case is included for storage and transport. This set is suitable for the following lenses: Sigma 14-24 mm F2.8 DG HSM Art lens and Sigma 12-24 mm F4.0 DG HSM Art lens. Package includes: 1 x rear lens filter ND 0.9, 1 x rear lens filter ND 1.2, 1 x rear lens filter ND 1.8, 1 x rear lens filter ND 3.0, 1 x adapter compatible with Sigma 14-24 mm F2.8 DG and Sigma 12-24 mm F4.0 DG.
