Haoge brand Bayonet Square Metal Lens Hood Because it's bayonet-style, it can be used while a lens filter is attached. I didn't like the tulip-shaped original lens hood, so I used this one. The design is significantly improved. The cap is not included. There are light scratches and minor abrasions from use. I used it on the SONY 40mm f2.5G and α7cii. It seems it can also be used on the 24mm f2.8G and 50mm f2.5G of the same series.
