[Neoprene] I’ve purchased this cover for my Sony 200mm-600mm f/5.6-6.3 from B&H. It is a well put together cover and I’m very happy and confident with the level of protection it gives. It’s very easy to use and install.

[Neoprene] Item fits well. Happy with the purchase.

[Neoprene] I'm happy of my easyCover lens Oak Neoprene cover for TAMRON (Forest Camouflage). And Fast delivery. Thank you B&H Photo.

[Neoprene] Fitting this cover on my Tamron 150-600mm G2 lens was releatively simple and quick. It provides some protection from the elements, and from scratches. I do not, however, have the cover on the lens barrel extension, because it makes the zooming operation very unwieldy. That said, I'm still glad I purchased instead of the more expensive options.

[Neoprene] This is replacing the second set of lens coats on a lens I have owned all of two years. Those start shredding almost as soon as I install them. I do not know about durability of this cover yet.

EasyCoat is easier to install, fits more precisely. EasyCoat has paid much better attention to accessibility of all relevant controls on the lens, and has a cut out that lets you see the numbers on the zoom ring. Very well thought out.

I feels better in the hand as well.

N.B; I kept the lens hood segment from the lens coat (so far). It has a small tab I repurposed to take a leash for my lens hat, this one I would have to modify. Not that it would be difficult to do if you are starting with this, just keep it in mind.
EasyCover, if you are reading this...

N.B #2: The lens is pretty well made, and I am not sure you need this for protection. It mostly will protect against scuffs, scratches, etc.
I use it because pointing big white things at birds doesn't always go unnoticed by said birds.
Sony, if you are reading this, make your bird lenses black...

[0.345 lb] This product is very nice only late for chipped in Saudi

[0.345 lb] I mainly got this as I noted that birds would spook with my zoom lens. It was easy to set up. Like other reviewers stated, you cannot add the piece for the moving part of the zoom unless you want this fixed. I mainly got this to not spook the birds and it is sufficient.

[Neoprene] This lens is hard to fit because of all the rotating pieces, but this cover does a great job. I bought it to replace the one by lenscoat (and get a darker color). It was designed with care, with cutouts so you can see the zoom setting and operate the switches directly instead of through clear plastic. I suppose the weather protection of the switches won't be as good, but operation is much easier. It is still slippery on the outside like lenscoat, so I will need to add rubber bands for better grip. It's a more thoughtful design and a better product, at a much better price.

[Neoprene] I bought this cover to protect my lens while photographing wildlife. It is easy to put on. I bought more for other lenses which I own to protect them.

[Neoprene] I like the added protection and blending into the woods
