Used Sigma 780-01 Lens Hood

Went straight onto my 150-600mm without any wobble, and the reversed storage position is a nice touch for quick access. Definitely cuts down the ghosting I was getting in bright sunlight.

The bayonet mount is snug enough that there's zero wobble, and it has noticeably cut down the glare I was getting shooting into the sun with my telephoto. My images look noticeably punchier now that the stray light isn't washing out the contrast.

It clicks onto my 150-600mm lens with a solid, reassuring snap and has noticeably cut down on flare during golden hour shoots. The bayonet mount feels sturdy enough to stay put in my bag without any wobble.
