Do I need to buy UV filter additionally? Can this Circular Polarizer fulfill the requirement of UV filter?

I use the clear UV filter to protect the lens from any contact that would harm the first lens element. Lenses have coatings that can get worn away from numerous cleanings and improper handling. The polarizing filter would protect the lens, but I wouldn't want to use it for every shot. I use mine to reduce reflection in glass, darken the sky and modify contrast, depending upon the situation.

The short answer is you need both. Circular Polarizers allow you to control glare and light diffusion - in other words, when you turn the filter, you can darken the image or lighten the image, as well as reducing glare from reflections or increase the "blue" in the sky as well, among other things. If you're going to take outside pictures in daylight - especially around reflective surfaces such as glass, metal or water - then having one of this is critical. However, Circular Polarizers (when rotated properly) will slow your lens down by 1-2 stops, so you only want to use them in brightly lit situations where glare, etc., is present. UV filters originally reduced ultraviolet coming into the lens in order to cut down or eliminate a "blue cast" on film, as well as to protect the very expensive "glass" at the front of your lens from getting scratches from constant cleaning. UV has long stopped being a problem, so now these filters are used primarily to protect the glass at the front of your expensive lens. They keep dirt, dust, finger oil and debris from touching your actual lens, so you never have to clean the lens itself... which means your lens will never develop scratches. UV filters are cheap to replace (by comparison to lenses and Circular Polarizers). They don't affect the speed of your lens, nor do they affect the color your lens "sees". I would suggest, though, that you get a good multicoated UV filter so ghosting and other reflective problems don't occur. All Circular Polarizers are already multicoated, so that's not a problem with them.

Also, cost about $25 t0 $30 from iSpring. Free shipping and cheaper by the pair. They also sell sets of 3 years of filters except for the UV lamp. Best deal I have found.

Sorry, I don't have the Kaesemann Circular Polarizer with Multi-Resistant Coating. Just the B=W 77 UV filter.

Art filters are special effects applied by the camera in software. A circular polarizer would be a hardware filter, which could be screwed in once the lens cover is remove. But the lens barrel is not marked with a filter diameter.

Takes a standard 77mm UV filter. Not sure if it creeps into the image. I can check.

I bought a 67mm UV filter and a 67mm Circular Polarizing filter. I bought the adapter from Amazon but it was sold by New West Direct. This adapter does screw onto the camera body as Jo Art has said and works great. From the imprint on the adapter ring it appears that the adapter is essentially a 51mm-67mm converter. After buying it I wondered whether it might have been better to buy a 51mm-56mm or 51mm-57mm or even a 51mm-58mm step-up adapter ring and use some of the filters I already have.

I don't own that lens, but from some reading around it appears that regular filters are fine; however, I will make note that circular polarizers on a wide angle will produce very strange results due to uneven polarization. That may or may not be a concern depending if you want to use it for creative effect.

yes it is uv absorbing and you only lose 1 and 1/6th stops of light, that is one of the great things about the HD and HD2 series of polarizers

Yes, but the threads for the filter are not very deep, and it falls off easily, especially the polarizer, unless you always rotate it in the correct direction (as in screwing it on.)Kathi

You can get a filter, but the depth of the lens hood obviates the need for it. I just got back from Australia shooting with the lens in all weather and conditions and did not use a filter. Better images that way as well.Regards,Evan

Depending on the lens, it's not usually a good idea to use both filters. UV haze filters are pretty useless and are usually mostly to protect the lens, which the polarizer will do. Unless you spend a lot on a UV filter, it's actually going to degrade the quality of the image. If you stack too many filters together you start to get a vignette effect because it lengthens the barrel of the lens, and the inferior glass will degrade the quality of the image further. Use the circular polarizer to reduce glare and reflections or to stop down a fast lens to use in bright light, otherwise use the UV filter or no filter.

I don't believe the polarizing filter will take care of UV filtering. The place I got the Tiffen polarizing filter bundled the two filters together so you get both.

May I ask where you purchased the polarizer and UV filter for the SX1? My husband would also like to use these. Did you also purchase your adapter from the same place?

I use a thin uv filter mainly for protection of the front element. It works fine! This is a great lens and I think you will enjoy it! Take care, Doc

Hello,I use B+W 39mm UV filter - check ebay. Lens hood and pancake lens? Don' t do it, it realy makes no sense. Br, Uros

You need a UV filter. Trust me, better for a $10 UV filter to get scrtched then your lens. And a circular polarizer is a must have especially since your shooting water shots.

yes, but. You need to have the clear filter in place. The polarized filter I have won't stay on without the clear filter first.
