The ALC-SH154 Lens Hood from Sony is specifically made for the FE 24mm f/1.4 GM lens. The hood has a petal shape design, which is made to block stray and extraneous light from entering the lens and causing lens flare. Also, the lens hood sustains accidental or sudden impact instead of the front element of the lens. It can be used as a spare or as a replacement to the original lens hood.
