Nikons HB-70 Bayonet Lens Hood is a must have accessory when using the NIKKOR 35mm f/1.8G ED lens. Designed in the shape of a crown, it prevents unwanted light from contaminating your image by ghosting or flaring. Its design shields just enough light to achieve this, and also enables you to take wide angle shots. This lens hood also prevents the vignetting effect when shooting wide angle images. This lens hood can be effortless screwed onto the front of the lens. Along with protecting from flares, it also pads your lens from accidental bumps and prevents abrasions or scratches.
