being more of a zoom lens guy i decided to get my hands on this lens as the price is just to good not to.being more into the zoom lenses it did take some time to adjust to the fixed focal length and using my feet as the zoom but for the image results its worth it.REMEMBER its under£100! - its light and compact - wide apreture of f1.8 - image quality is competes with the canon L series - THE PRICE!!!it has an all plastic, almost toy-like body top to front to back but as long as your not just lobbing it about theres no reason to be concernedIt is a good lens for low light photography, especially indoors. Note that the filter thread does not rotate on autofocus, so you can happily use a polarising filter.This is a great introduction to photography with a prime lens.

You can pay a lot for a polarizer Filter, but at this price and after studying reviews, I took the chance on this, results are an improvement where the situation to need this arrises.It does reduce reflections and increase saturation of colour as expected.It does darken the amount of light passing through the lens so it will mean slightly longer shutter speed or higher iso, but you will be using this most likely infairly good light and if not say a rainy night shot on a tripod.I did find some addittional lens flare in very difficult almost front on photos, but generally this can be avoided and the lens was not needed for the photo and should have been taken off.All in all not bad for the price you pay

Great ND filter that does the job of stopping light without the extra expense attached to your pockets

Pros:- Outstanding sharpness, saturation, and bokeh- USM AF is fast and quiet- 2 focus range settings- Fast f/2.8 throughout zoom range complements 24-70mm f/2.8L- Image Stabilizer- 2 IS modes: 1 - normal & 2 - panning- Weather sealed- Common 77mm filter among L-series- Front element does not rotate with focus- Non-existent zoom-creep (lens does not extend)- Solid construction and feel- Focus range indicator window on top of lens- Comes bundled with lens hood, tripod collar ring, and standalone lens bag- Well controlled vignettingCons:- Heavy- Expensive- Longest of the 4 Canon 70-200mm'sThoughts:Outstanding Lens! Always use a filter and use the lens hood as much as possible. The lens hood does get in the way of using a polarizing filter since the front element does not extend. Front element does not rotate when focusing. One of my more favorite lenses. It is used in conjunction to my 24-70mm f/2.8L. My 1.4x extender is only used when I want more reach, but it does cut the sharpness down a bit. I love the IS on here. The ability to change IS modes is awesome. Having 4 setting switches on the lens is a step up from the 24-70mm f/2.8L (that having none). The white finish on this lens garners a lot of onlooker attention. You'll get a ton of attention at events and need a monopod if you want to use it for a baseball game and the like. 24-70mm f/2.8L seems light after wielding this lens. This lens attached to a 40D will not fit the Lowepro Slingshot 200 in the quick draw position. That said, I never use the included standalone lens bag (it looks more like a tan & black lens holster; comes with a thin black shoulder strap). It's best to get this on sale (Christmas season comes to mind). The $1700~ price tag is steep, but the $200~ in instant rebate is nice.Bottom line:Outstanding Lens! Highly regarded and recommended.

Every good lens MUST have a UV filter. This one is excellent. It does not seem to affect the color nor the exposure. Pictures come out crystal clear.

After purchasing the Nikon D600, with lens, I needed a polorizing filter and this works out just perfect. I take a lot of pictures around the beach and ocean, this filter does come in handy to help eliminated the glare that occurs sometimes,and deepens the colors.

When I purchased this UV filter I had low $ in mind because I was going to be using it on a lens that I paid under $120.00 for and wouldn't be using all that often. Every lens needs a UV filter for protection and it actually does a pretty good job. For some of my more expensive lenses I've gone with Hoya multi-coated or B&W filters but the bottom line is this Tiffen filter works good for a low price like $13.00 or so.

I’d chalk this up to the actual lens being smaller than the filter. This is more of canons doing.The little bit of difference I can see, seems nice. But it’s really only a lens protector at this point.It does help with overall contrast !Materials seem good.Oh and it does get stuck into the lens. Won’t come off without force. I mean FORCE!!
