Multi-Coated UV Lens Filter (72mm)

Pros: This product is what it is, a circular polarizer. it works just like other circular polarizers. the price is simply amazing comparing what other CPLs out there, they're in the range of at least $80-200. the construction, as usual is a linear polarizer with a quarter wave plate to create circular polarized light. which enables the autofocusing mechanism in the camera. the turning of the CPL is smooth, it doesn't slide, and it can be twisted tightly onto the camera lens

Cons: not multi-coated, see ghost under very strong light and dark-backgrounds, e.g. shooting a light bulb... the glass was loose when shipped to me, but you can tighten it with the ring on the outside. the thread is a bit short going onto the lens, and short on the other side, so putting on the lenshood is a bit odd...

Other: a very very worthy buy, unless u shoots outdoors or with lots of reflections all the time, you don't need this. since it cuts at least half of the light into the lens (due to the linear polarizer at the front) you wouldn't want to use it in dark places anyways, it's ont something u'd want to keep on your lens all the time. so i suggest get a cheap one and use only for the rare occasions.

Pros: Very inexpensive for a MC filter. Well made. No distortion in glass. Cheap way to protect your lenses. Doesn't seem to introduce any noticeable color cast to images.

Cons: The MC coating is much lower quality compared to the high quality coatings used in camera lenses and eyeglasses. There is more flaring when shooting towards a point light source compared to just shooting without using this filter.

Other: Good for general lens protection and probably better than just a plain glass filter for just a few dollars more. Don't buy this expecting the same MC treatment as other higher priced name brand filters as this is 4-10x less expensive. Try not to shoot towards the sun or other point light sources and you should be okay.

Pros: Made of glass and seems to filter out the UV rays when comparing shots with and without the filter. Good cheap filter if you need a quick solution before spending hundreds on a Hoya etc.......

Cons: Cheap quality.

Other: For the price, it's definitely worth the buy.

Pros: Cheap, ease to use, durable (I use it more than 3 years). Good enough for wide angle or middle range photo lens. The only sign of use is that the white marks on the side of the ring are almost erased.

Cons: Optical quality is not sufficient for telephoto lens or for long end of the wide range zoom lenses. Visible blur occurs if use with telephoto longer than 200mm (DX format).

Other: Good for lens protection - for wide angle or middle range photo lens. No problem if you don't use it for telephoto lens.
