KUVRD - Universal Lens Hood - Fits 99% of Lenses, Holds 99% of Circular Filters, 2-Pack - (1 Small, 1 Medium)

See attached photos. I received my lens hoods this week and took them out for a test on March 1. The medium lens hood fits my 150-600mm with a little stretching. I think I could have pulled it further onto the lens, but I didn't see any vignetting. Next I tried it on my 100-400 and it fit much better and worked great. Third, I tried it on my 24-70 f/2.8 and it worked great with no issues. Lastly, I tried it on my 11-16 f/2.8. With this one, I had to retract some of the hood back to avoid vignetting. But, that's understandable since it is a wide-angle lens.Overall I'm very pleased that I can just put one lens hood in my camera bag and the KUVRD medium will work fine for so many lenses. I also tried it on my 70-200 f/2.8 and it works like a champ. 5 lenses and just one lens hood. That makes things much easier. No searching around for where I put the lens hood. Also, it folds up small for easy storage.NOTE: The KUVRD-small works great with my 50mm f/1.8. Just two lens hoods for every lens in your bag!

If you are a photographer and don’t have any Kuvrd equipment you are missing out.1) Lifetime guarantee. No joke. My lens covers all broke over the 3 years I owned them. I asked about replacement (not expecting too much - maybe a small discount), and they sent me all new covers.2) Ease of use is amazing. Flexible enough for multiple lenses and easy to pick and store when not in use.3) Specific to these hoods... I have a canon 70-200 lens with no hood. That hood is way expensive. This does exactly what that would do, takes up less space, and I can use it up through windows to get rid of reflections on multiple lenses.Add this to your toolkit.

I travel with a lot of photography gear. These flexible adjustable lens hoods save considerable space by eliminating multiple lens hoods and the protective padding. I bought the 54- 76mm and 72-112mm size KUVRD universal lens hoods through Amazon. They go on easily, at least at the smaller diameter in the range, and stay on very well, allowing you to adjust the depth of the hood extremely easily. So far, I am happy with this purchase and value provided.

I ordered the small and medium sizes. After attaching to various lenses I own I can say... They are very slippery when being attached and after being stretched over lens. This slipperiness allows them to move around on and in many cases pop off the lens. Many lens place their focus ring at the front of the lens and this has to be install on the focus ring or past it on the lens body. This situation seems to result in unsatisfactory results of blocking the focus ring from turning or the hood falling off lens. The lens that it can fit on and not interfere with the focus ring still has one last issue that the material is weak and pliable and has a tendency to flop. I believe that these are usable with the right lens design and if you have time to stretch and position on the lens properly. Otherwise the not so much.

PRELIMINARY REVIEW: I have a trip coming up next month, and I'll update this review once I've put it through its paces. For now, these are my initial thoughts on the product.4/8/21: I ordered the small and medium sizes to use as a "2 sizes fits all solution" for 4 travel lenses: Tamron 70-180 f2.8 (67 mm), Sony 20 f1.8 (67 mm), Sony 16-35 f4 (72mm), and Sigma 24-70 f2.8 (82mm). I'll start with the easy ones, which are the Sony prime and the Tamron. The size S hood fit both of these lenses and didn't interfere with their functions, although it took a few attempts to attach. I can see myself leaving the original lens hoods at home, no problem, when I'm trying to pack light. Next up was the Sony zoom. Both the S and M fit this one, although the M was easier to put on (still took multiple tries with both and was definitely a challenge with the S). I'd probably prefer to use the M, but I'm running into 2 issues: the first is vignetting at the widest angle (and if collapsing the lens hood defeats the purpose). The second issue is interference with the zoom mechanism. This is where I might want to compare both sizes and see which one best addresses these issues.The Sigma zoom was an issue. Getting the hood on wasn't easy, and it tore on my third attempt. This is where KUVRD's exceptional customer service comes in. A quick email to them, and I received an apology from Cary (the company owner) and assurance that I would have a replacement within the week. I received the replacement today, but my follow up attempt to put on the Sigma was still a struggle. I'm thinking maybe it might not be meant to be for this lens, but will continue to find the best way to attach it.Knocking off a star because I'm finding they really aren't that easy to put on. I probably need to practice putting them on/off, because it looks a helluva lot easier on the KUVRD videos than I was experiencing first-hand. All in all, the idea is great and if it works as advertised, it will make my travel kit that much more compact.I'll update this once I've used it more, but my early impressions are promising and the company stands by its product for sure.
