Canon EW78BII Lens Hood for EF 28-135mm f/3.5-5.6 IS Canon SLR Lens black

The media could not be loaded.  Designed to prevent stray light from entering the lens in order to keep unwanted glare from affecting your photographs. In addition to eliminating light flare it also will improve the protection of the lens from accidental impact. I like how the inside of the lens hood is covered with a felt like flocking material to eliminate reflection and scratches that could possibly reflect into the lens and photograph.The lens fits snuggly and feels secure. It will mount in the reverse mode but it does make the lens with the hood too big in diameter to fit into my lens bags. Mounting the lens hood backwards may let it fit into your camera bag easier depending on how much space it has.I like this lens cover a lot but I wish it would fit into my lens bags while on the lens so I didn't have to carry it separately. I have included a short video of the lens and how it looks on your camera and the size when compared to the lens bag. I hope it is helpful to you.Benefits:* Keeps your lens cleaner from wind-blown dust, rain or mist.* Shades the hood to reduce light flare, discoloration or hazy images caused by stray light.* Improves contrast and photographic image quality.* Pedal shape works effectively while reducing the added weight of the lens hood.* Protects your lens from accidental drops and bumps (in a limited manner).* Inside surface is coated with a mat velvet style flocking to eliminate reflection and reduce scratches that could be reflected into the lens.* The lens hood will mount backwards on the lens for storage.* The lens hood mounting is snug and tight on the lens.Cons:* Does add length to the lens (As expected) and makes it harder to store. (Adds 2 ¼ inches to the lens length)* Adds diameter to the lens so it does not fit into my large lens bags even when reverse mounted on the lens. (The lens hood is 3.9 inches in diameter)This is a very good product and I rate it 5 stars. I recommend it to you.

I can't say much to argue the point that some others have mentioned about a cheaper version (from another manufacturer) being just as good as this model. I own only Canon lenses and I have always purchased genuine Canon Lens Hoods for them. This Canon EW78BII is a perfect fit for the  Canon EF 28-135mm f/3.5-5.6 IS USM Standard Zoom Lens for Canon SLR Cameras . The hood seems pretty well made (although it is plastic), installs easily and fits perfectly.I have only shot a few pictures since installing this lens hood, but I can honestly say that it offers a bit of improved contrast and definately cuts back on stray light hitting the lens. I particularly like the petal shape of this hood, vs a typical cylinder shape found on most larger zoom lens hoods. I have shot a handful of pictures using a flash, and there is no vignette shading anywhere on the photos. This is a wonderful feature, since it looks as though the hood will not need to be removed for indoor/flash photos. As far as protection goes, I don't know as though this hood will prove to be much of a lens saver. Still, every little bit of added protection helps. As others have pointed out, this hood WILL increase the amount of kit storage space in your bag, but if reversed at least it does not add extra height to the lens.Overall I would recommend this lens hood, for improved picture quality, reduction of lens flare, and for some minor protection to the lens itself. I do agree that Canon has overpriced this lens hood, but what doesn't Canon overprice? All in all it is a well built, solid investment.

I am an amateur photo enthusiast who loves taking pictures. I read several good reviews regarding having a lens hood, hence I was convinced to purchase one. My experience after using it tells me that it has both plus and minuses. On the plus side: It adds protection to the lens from impact. It prevents glare from hitting lens area when used for exterior shots during glaring sunlight conditions. Some disadvantages noted: It extends the overall lenght of the lens hence makes it bulkier to carry around especially in crowded places. Secondly, the lens hood casts a shadow on the subject when taking pictures using the built in camera flash when the subject of the photo is in close proximity to the camera lens (say less than 3 feet). You are better off taking the lens hood off or using a dedicated flash mounted higher.With the disadvantages mentioned above and you still decide to have a lens hood on. I recommend getting the original Canon lens hood. It is made of good quality plastic material and fits well on the lens. No difficulty taking it off and on, although pricier than other aftermarket makes that does the same job.

This hood from Canon fits the lens perfectly, and is easy-on, easy off, with a twist lock action. It can be mounted "backwards" with the twist lock as well for storage on the lens without elongating the lens. I find myself using it at night as well to block bright lights on the perimeter of the shot. Really makes a difference in glare. The inside of the hood is nicely lined with a non-reflective material so that light that does get "in" doesn't reflect back to the lens face. My only gripe is that with the hood in place, the lens cap is a bit tricky to get on and off, and polarizer adjustments have to be carefully managed to avoid those nuisance oily fingerprint smudges if your fingers "miss" the rim of the filter. For mounting the hood, no need to line up the red dot on the hood with the red dot on the lens, you can just put the hood on and twist until it locks. It will lock at either 90 degree's or 270 degree's - you can't mount it with the wrong orientation! "Matches" the lens nicely as well. I just wish Canon would supply the hood with the lens in the first place. Fast shipping, nicely packaged, good transaction.
