Samyang lens hood for AF 24-70 F2.8 Sony FE. The lens hood (also known as a lens flare or sun visor) reduces light falling onto the sensor from the side. The so-called lens flares (light fringes) are reduced, which increases the image quality. The use of the sun visor makes the pictures look less dull and low in contrast. In addition, the sunshade offers a certain protection of the front lens against rain and light bumps or touches (fingerprints). For space-saving transport, we recommend mounting the sun visor "upside down" on the lens.
