[0.145 lb] Great lens hood. For the price, it can't be beat! Solid construction.

[82 mm] It is easy to clip on or reverse. I use it on my FZ-80 and it clips the corners at 20mm, but at 21mm the corners are fine. A small price to pay for an easy on/off hood. And as always, B&H was easy to do business with.

[82 mm] The lens hood is easy to use. It has functioned well during it's use in the day time.

[0.145 lb] Sensei Quick Clip Lens Hoods are the best aftermarket lens hoods made. Similar capabilities to expensive dedicated lens hoods, the lens hood is reversible & center pinch caps & non-rotating filters can be attached without removing the hood.

[0.145 lb] I have an elder 82 mm Sigma 17-40 Lens that I lost the lens hood a while ago. After searching in my country (Norway), then the main countries in Europe I found the lens hood at your place. Not the original one but a much cheaper and better one that is reversible and also easy stored. The lens hood was promptly delivered together with a portable harddisk. And I was satisfied - it fit and was made for the lens and thumb up from me at last!

[0.145 lb] This is a great lens hood that quickly clips on and off plus will reverse-mount for storage. It is particularly good for vintage lenses made before such convenient lens hoods became common.

One hesitation I had with the hood is the fairly high force to clip it on and off. I completely eliminated this problem by adding 4 grooves in the mount that align with the 4 ball bearings in the hood. The grooves are
positioned such that when the hood is at 45 degrees from level, the ball bearings align with the grooves and the hood easily clips on or off. To secure the hood, rotate it 45 degrees to the correct level position. It is easy to align the bearing with the grooves because
the ball bearings detent into the grooves when aligned. See the two annotated photos.

To precisely locate where to make the grooves, screw the mount on to the lens that will use the hood. Put the hood on the mount at 45 degrees from the correct "level" position for the hood. Mark the position of the
hood on the mount or tape them together. Unscrew the mount+hood assembly and repeatedly clip the hood on and off without rotating either until the four ball bearings mark the aluminum mount exactly where to cut the grooves. I cut the grooves with a Dremel tool but
with patience could be done with small files. Slightly flare the opening to the grooves so the hood detents into the grooves when the are aligned.

If you want to make it even better, you could slightly widen the ball bearing track (do not cut a groove!) at the four locations were the ball bearings sit when the hood is rotated to the proper "level" position on the camera. Then you have another detent where the hood is properly oriented on the lens.

I wish these hoods came in versions specific for wide angle, normal, and telephoto lenses.

[0.145 lb] I use this lens hood on my Sigma 18-250 mm lens.It's a lot easier to use than the one that came with my Sigma lens.

[82 mm] Bought this for my Nikon 50-250 and it works perfectly. The lens cap firs securely in the attachment ring when the hood is snapped off. Nice item, recommended.
