Ultra-Thin UV Camera Lens Filter (58mm)

Pros: The first to be mentioned is its price. At about 1/10th of the normal price for a simple UV-filter, this costs about the same as a (cheap)hamburger.
The ring is made from metal.
There is no obvious degrading of the photo quality, even in strong lights.

Cons: The glass is a bit uneven in some places. Doesn't seem to do anything to the quality of the photos though.
Screwing the filter onto the lens was a bit tough. Still works to put it on though. You don't have to struggle to put it on but it felt as if the threads were a bit smaller than normally. It also makes a loud squeaky noise when putting it on and off so don't change filters when trying to sneak up on an animal.
Most people put on a UV-filter and then leave it on forever though so this is not that big of a problem!

Other: I'm using this with the Canon 55-250mm lens, and there is no obvious loss of quality. Some lenses are move sensitive than others though, keep that in mind!
If you need a simple UV-filter for your lenses, I'd recommend this!

Pros: very nice product ... excellent cost / benefit ratio, very good product, came without any damage, the packaging is quite sturdy, and it comes pretty safe, does not cause interference in the pictures, besides being a great protection for the lens...

Cons: the glass is quite thin, and this gives an impression that the filter is very fragile ... also to put it on the lens it makes a noise that makes me think it may damage ... I think it should not be removed often

Other: ideal for those who want to protect the lens with a filter without major interference ... my case!
