JJC LH-SH131 BLACK petal-style bayonet Lens Hood replaces Sony ALC-SH131 lens hood. The main body of the lens hood is made of premium aluminum alloy, which is durable and lightweight. Besides that, the bayonet adopts ABS material to avoid unwanted scratches to your lens mount. The non-glare matte finish on the inside further prevents or limits lens flare. No vignetting will show with the hood on. The hood can also be placed backwards over the lens for more compact storage. The hood allows you to put on a Ф49mm filter and a Ф49mm lens cap.
