This filter has changed the way that I do photography! When I pair this with my f/1.8 prime lens, I can get amazing depth of field shots in broad daylight without having them being blown out or overexposed. This made for some great Senior photos. And, I can take some great long-exposure shots during the daytime of waterfalls and things. I would definitely recommend this filter to any photographer looking to accomplish these things.There are a couple of drawbacks to this filter however. If you want to use this filter in combination with others such as a UV filter, this needs to be the filter on top. The mount on the top of this filter (not the side that attaches to the camera) is 55MM rather than 52MM. This means that with this filter on, I cannot attach my lens cap or any other filter. I ended up putting my UV filter onto the camera first, so it's not a big deal. The only other thing is that the arrow indicating what level of ND is being applied is on the bottom of the filter, so I have to flip up my camera to check where I'm at. I saw other reviewers commenting this as well.Overall, I like using this filter and I have gotten some great shots with it. Would recommend to any amateur photographer looking to step up their game.

Only had the filter for a week or so and taken a couple of test shots with it on the lens. Got to say that so far its a good purchase. Well made, nice thin profile, no colour cast that I can see. Will be going to a birds of prey centre in a week or so and put it through its paces.Great company, sustainable packaging, came with a micro fibre cleaning cloth and they have planted 5 seeds towards regrowing forests. DONT SPEND A FORTUNE ON THE BIG NAME COMPANIES, buy Gobe filters they do exactly the same job and help save the planet at the same time :)

I absolutely love this lens! I am getting beautiful shots of the moon up close and personal!

Easy to carry around. Easy to use. I have taken some great shots of the moon with it.

Haven't had a chance to use it in daylight, but used it for a couple of shots at night like moon shot with my 300mm lens and helped alot.Fits Great! and great way to protect your lens.

I recently moved into the category of "serious impassioned amateur photographer" and, after a healthy dose of research, purchased the Canon 20D D-SLR (see my previous review of the camera and experience with it). As is necessary to all impassioned photographers, the lens selection(s) is tantamount to the best photo, as seen by the photographer's inner eye. As a result, when I decided to purchase the 20D, I wanted the broadest breadth of lens exposure possible in the fewest possible lenses.In large part, my search came to a rapid halt when I ran across this lens, the Canon EF 70mm-200mm f/2.8L IS USM Telephoto Zoom lens. While this lens is heavy in terms of weight (approximately 2.9lbs) and price, it is easily the best lens purchase I've made, hands down. I have paired this lens with the Canon EF 24-70mm f/2.8L USM Standard Zoom lens and a 2x telephoto extender, and I am set for most any shoot. I have read reviews regarding quality degradation when shooting with the 2x extender however, I've not experienced that (perhaps it is my inexperience...but my photos don't show it!). The 2x extender has provided me with exposure options from 24mm to 400mm, with the high quality expected from Canon "L" lenses.A few words about IS (image stabilization)...I love to take shots of the moon. First, to get really great shots, one must have a reasonably telephoto lens (that is, if you want to actually see the cheese). The next issue is simply, how do I keep the moon from looking blurry even though the night is totally clear? The answer is simple: get a tripod or get a Canon lens featuring image stabilization. The IS feature has allowed me to take my best moon shots yet, and yes, the cheese is quite visible and quite clear. IS is a must for those shooting without a tripod.All told, this lens is incredibly rich in features, handles well for a large telephoto, has a tripod bracket for easy attachment to a tripod, and is pretty much the nuts for those of us not fully versed in photographic knowledge. While not the most inexpensive lens around, the features and product results afforded by this lens is well worth the cost. I'd buy it again without hesitation.

We just returned from Yellowstone. The polarized lens made a huge improvement over the no filter shots. I compared a couple pictures with and without and the without shots were all washed out. My wife made some simple edits before photo sharing and she said the time was cut way down in part due to the new camera and in part due to the polarized lense. I would absolutely repurchase.If anyone is wondering about the sizes, they relate to the diameter of the lens not the thinkness of the filter (I'm new to photography). The lens on your camera will have the lense diameter printed on it

I purchased this lens to use for sports shots and it has not yet failed my standards. Recently I was at 'Head of the Charles' in Cambridge Mass and almost every picture I took came out wonderful. For those that do not know of it, 'HOTC' is the biggest, and most famous regatta race in the world. The Image Stabilization is a dream...Some shots that I would never have a chance to capture, I get so easily now!While I have heard that this is not a lens to use with a tripod, I do use a one for some set shots and those always come out great. The only real drawback of this lens is the weight, but it really is not THAT bad. Just get a more comfortable camera strap (the ones that come with the cameras, I NEVER like) and you will find that carrying this lens attached to your camera is no different than carrying another quality lens. The white paint will draw some looks, so you have to think about that as well.Also, another side effect...As this is my first "L" lens, I am really itching to buy more! I'm totally ruined from purchasing "Non-L" lenses now.Come on Christmas bonus!!!
