Hoya72mm HD Digital Circular Polarizing Screw-in Filter

This filter despite of its high price does not fit the 77mm lens (Sigma 50mm F1.4 DG HSM Art Lens for Canon).It is impossible to keep it on the lens for more than a couple of seconds, it jumps off the lens. I am not sure if it is only our filter that is faulty or it is just crap in general. Anyway it does not fit my 77mm lens and after being on a holiday we wanted to return it but it is too late now to return or exchange it with the properly working one. Just AVOID, do not waste your money and time.

OK, before I say how brilliant this polariser is we need to clarify one thing, not all polarisers are created equal and a cheaper polariser, even a good one, will knock off a few extra stops of light. In fact in my experience even good hoya ones will kill your ability to shoot hand held in anything but sunshine.However this is a beauty of a polariser and as it states it let's in more light, which it does very well indeed. Been shooting now for a month with this filter and I can honestly say its the best I've ever used, can be a bit tight once it's on but let's face it you don't want to unintentionally unscrew it when you're out and about.5tars all round

You want a circular polarizing filter. This kind of filter removes a lot of reflections, softens the hard midday light in your photos and improves contrast. It makes colors pop especially the blue sky will suddenly look gorgeous but it will also make grass and leafes look greener and more "juicy". When shooting pictures of water, fx the ocean, the surface will suddenly be transparent instead of a shiny blank surface, and you will be able to see either whats below the surface or a beautiful deep blue color. Picture of any item with reflections from light can be magically improved, as it removes the reflections in many cases.Be advised though, it does reduce the amount of light that reaches the sensor in the camera, so you should remove the filter in low light situations and if you need to take pictures of moving objects (sports, kids). Not a great filter for street photography early or late in the daye but fabolous for holidays.This particular filter from Hoya I have mounted on a 35mm Nikon prime lens, it is a normally sized filter (not thin) that works as advertized.I you havent seen a circular polarizer in action, you should buy or borrow one. Chances are, you will keep it and love it.

Very happy with my new 67mm hd polatising filter. Arrived well packaged and on time. I am using this on my Nikon 16-85 mm lens and at 16mm there is no vignetting and no notible loss in image quality. Makes a huge difference to the blue skies and clouds, grass is greener and water and glass clarity are superb as that's does an excellent job at eliminating glare. Would definitely recommend and the price is superb athe £30. Absolute bargain.

I bought this polarising filter in mid-June after reading a review of polarising filters in "Advanced Photographer", in which it was awarded "Best in Test", but was rather expensive. It was a pleasant surprise to find it available from Amazon at just over 1/3rd of the usual price.I have now used it for about 6 weeks and I am very pleased indeed with it's performance. It works really well darkening blue skies, improving contrast between clouds and sky, and brightening the landscape generally. It has improved my landscapes considerably. It reduces reflections in water quite well, but did not remove reflections in images that I took in an aquarium, although perhaps this was too much to ask.It is very easy to use and is so thin and transparent that I hardly noticed it on the camera, it certainly did not reduce exposure by any noticeable degree. The front, rotating element of the filter has an arrow marked on it which made it very easy to reset to a standard position between shots. This feature made it quick to set for different photographs, with different lighting. It was also very easy to keep clean over a longish period of use, even greasy finger marks and damp spots came off easily. One very small niggle is that the back filter element is so thin that to remove the filter from the camera I had to hold the front of the lens very firmly indeed to start the filter's screw turning.In summary, I can thoroughly recommend this polariser.

Hoya 77mm HD Polarizing Filter.This a must have if photographing in bright light, especially when taking photos around water.Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colours providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.A brilliant all rounder kept in my camera bag at all times.

This is a fantastic filter.I bought it initially to use with a dash cam and to kill reflections from the windscreen. It worked great for that day and night (these Hoya HD filters let more light through which means they perform better at night).I then took it on holiday to use with my DSLR camera and some of the results are absolutely amazing.I never realised it in the past but a lot of those amazing holiday photos you see in the brochure are just taken with filters like these - the sky will go a darker shade of blue, the clouds will pop and you'll be able to see the details at the bottom of the sea instead of just the sun reflecting from the surface.
