The Aqua Tech SoftHood, being light and collapsible and very difficult to damage, is a practical alternative to the originally-supplied metal or carbon fiber hoods that you find with the enormous lenses for SLR cameras. This particular model fits any 500mm f/4 and 300mm f/2.8 lens; it comes with a pair of compression straps to perfectly affix the SoftHood to the outer diameter of your lens barrel no matter the maker.
SoftHood's faster to deploy than a 'reversed' normal hood since you just extend it from its collapsed state and of course with a name like Aqua Tech it was designed with excellent water resistance in mind.

I have been using this product for over one year. I bought it primarily because it can be packed flat, and I really did not think I would use if for local shooting. In short, the OEM's pretty but scratchable hood went back in its box and has not been seen since. Although not any lighter (maybe even a smidge heavier),this hood does everything the OEM hood does and is easier to use. You adjust it once - read the instructions about how to get the right tension - then it snaps on and off and reverses without having to fiddle with a screw. You do not need to unbuckle and rebuckle the straps after the initial fitting to your lens. It stays put and properly aligned at all times. It is stiff and stable enough to easily support the weight of the camera and lens. I store my lens vertically mounted on this hood. The best thing about this hood is that it does not scratch and it offers a little cushioning/protection for the lens. You really appreciate that when you accidentally bump it into a rock or something when you are out on a shoot.
I thought about making a hood like this once because transporting the hood for the 500mmf/4 on planes and in a packed backpack is difficult. The idea would be to have a lightweight device that folds flat or rolls tight and does NOTHING MORE than be a hood. This product weighs as much as the hood it replaces. Although I could lay it flat in a suitcase, once I have it at a photo destination there's no place to put it ... won't fit in any camera bag, is bulkier than the Canon hood when on the lens, takes longer to mount. The ribs to allow standing the lens on the hood are really unnecessary.
