This JJC metal sun canopy is suitable for wide -angle lenses with a filter size of 82mm. A sun hood shields your lens from unwanted incident light and minimizes the occurrence of a color hostage or a lensflare. A sun hood also offers extra protection to your front lens.
A sun cane for a lens that has a large Has image angle is different in shape than a normal sun hood. This is due to the bulging of the glass and to prevent vignette. Vignette is the name for the creation of dark corners in the image.
