[77 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.

[77 mm] By far not only does it do its job, but the best part is that your filters up to 95mm can live on your lens! It wont interefere with snapping the hood on and off! This is great for those of us who use like a shoulder rig and can't get a matte box to fit, or a clamp on is too heavy (perfect for gimbals) but you need to stop stray light. For example, my Genustech 82mm filter lives on my sigma 18-35 and when I dont need the hood, I remove it no problem without removing the filter or the screw on metal lens cap I use. Sensei is by far the best producer of simple lens light protection and filter usage/protection. THE ONLY thing I wish is that there was a 'quick clip pro' version where the hood was completely round like their 'pro' screw on lens hood. Annnndddddd (sensei if you're listening) wish the pro version was aluminum again like their pro screw on lens hood. I would get this immediately and look nowhere else for lens hoods. Why this hood versus the stock one that comes with your camera? Simple one word.... helpful. And isn't that what we want? products that are helpful and allow us to get the job done with ease while being intuitive and innovative?? Sensei knocked this ball out of the park!

[0.17 lb] Read the instructions, pay attention and you will be very happy with this lens hood. On and reverse is great . Again the price was great. A winner. Welcome to the family. Not sure what to do with the old lens hood.Any suggestions? Be nice!

[77 mm] Clipped onto my 18-300mm nikon lens as if it came with the product! With the sun protectors revolving you can take pictures at almost any angle to the sun. At last a lens hood that works Cheers Ross

[0.17 lb] Especially for lenses with no rotating front piece that don't have a dedicated hood.

[0.17 lb] This item seems to work well and wasn't a bad price either! Highly recommend.

[77 mm] 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.

[0.17 lb] Very good replacement of original.

[77 mm] Very functional lens hood. It's 2 pieces where the main piece screws onto the lens and allows the 2nd piece (lens hood) to easily be rotated and snapped on and off for storage. Sturdy construction and great price.

[0.17 lb] It has really been good and very useful, the system very comfortable and the quality very good.
