Exactly as they are supposed to work. Used to take solar eclipse. Worked perfectly.

Bought this and a solar filter and iPhone holder for the 8/21 solar eclipse. Served its purpose very well.

I have both the 52 and 58mm circular polarizers from Tiffen and they both work fantastically. The outer ring spins easily and smoothly, and the filter doesn't reduce the image quality one bit. This is a must have for taking outdoor pictures as it really makes clouds pop and cleans up reflections. Want to get a shot through a glass window? Use this filter to prevent unwanted reflections from getting in the way. Like your framing and exposure, but getting blown out reflections in that lake? You'll lose a stop of light, but it's worth it to get rid of those stray sunbeams in the water.I've taken them both on numerous hikes and in some fairly dangerous conditions. I've thrown them in my camera bag without much regard to their safety, and yet they work fine without any scratches. For the money, Tiffen is great.

I really liked this filter. I got this filter with the intention of the Solar eclipse that just occured. I am very happy that I got it and will be using again.

I was specifically looking for binoculars for the eclipse and somehow got routed to these without realizing that they are NOT solar safe binoculars. My bad for not reading the description well enough. They seem to be pretty decent binoculars, though, even if I have no use for them. Maybe I'll take up bird watching or something...

Finally got to use my new filter. Purchased specifically to take pictures of the solar eclipse. Worked as expected and couldn't be happier. Would definitely buy again.

Great filter but I was looking to use it for last years eclipse and read everything that was on the site about using for the eclipse. Fortunately an astronomer friend kept me from burning out my equipment but showed me other uses for this filter.

The AmazonBasic Circular Polariser 58mm is a slightly unusual acquisition as my photographic filters tend to be from a known and trusted photographic specialist brand, or sometimes from the camera brand. There had been a very few exceptions but they were usually effect filters for occasional use rather than one that would or could be often used.There are at least two lenses in my collection that have 58mm filter threads but only one circular polariser had been previously purchased on the assumption that only one would be needed. This will, at least, provide some extra flexibility. Unlike some, it does not appear to include a position marking (a dot, arrowhead etc) that some have to aid the user although it isd not a major issue. Ease of rotation is reasonable if not buttery smooth, but it is expected from a lower-priced product and in-line with many others. If you want smooth, it may cost you £80 or more.There are no obviously visible flaws in the filter and it does not appear to suffer from any optical errors that may either affect my images or interfere with metering, focussing and other camera systems. These filters can be rather expensive so an opportunity to try one that is not could not be missed.It would therefore be a worthwhile addition to your camera kit, providing not only a mild neutral density filter - useful in itself, but a means to darken skies, remove reflections from water, snow, metal and so much more. This could be one of the most useful additions to a system.
