I bought this filter for my Canon EF-S 10-22mm, just before going on a vacation and have used it extensively for about 20 days and as expected I am very satisfied with the increased color saturation and decrease reflections.

Here are my observations:

1)Observed slight vignetting when used directly on the lens at 10mm.It's a shadow like vignette(sometimes depending on ambient light,it's not noticeable at all) and you can still get details out of the vignette with a photo editing software.

My biggest worry with this filter was Vignetting on my Sigma 10-20mm lens. Received this filter the very next day after placing the order. I must commend Flipkart for their service.
Good news is there is no Vignetting at 10mm with this filter. A big relief I must say, otherwise I would have had to compromise shooting at 10mm.
My next test was to stack one more filter (ND i.e) with this one. There is good amount of vignetting at 10mm on the corners, but it disappears at 11.5mm and beyond.

Fantastic filter for the money you pay for it. I have used this CPL stacking with 2 and 3 stop ND filters and also with GND filters. Results are excellent. I had a chance of using my friend's Marumi filter. Results are definitely good, though not better than Marumi.

The only issue I faced with Hoya CPL is the delicate fixture ring that fits on to the ND filter & Lens. These rings are too delicate and prone to get broken even with a little more pressure while removing the CPL from lens or ND...

Many people don't understand polarizing light, so they expect more from these filters than they can deliver. Polarizing filters depend upon the angle of the light essentially being at right angles to the axis of the camera lens. When used with a very wide angle lens, the likelihood of that light being at a uniform angle to the axis is about nil. As a result, when you look through the viewfinder, and rotate the filter, you should expect to see non-uniform darkening of the sky, when used with a...

Excellent Performance. Very Good product.

Item looks to be used... the filter is not clear. there are patches in between.

I have bought many items from Flipkart, but this one was not the best quality.

I am glad I bought it. My photos have improved drastically. The build quality is good. Got the delivery within stipulated time.

instantly adds value to your pictures. worth the price. it was very well pack. i generally keep it short.. so all the rest of BS for 100 characters to complete.
