A very nice filter. So far I cannot complain. It does not seem to produce sun flares or any other noticable distortion like cheaper filters will.

Out the box, the filter comes clean and pre-oiled and ready for its use! I clean it at least once a year, mainly because i live in a dustier city compared to most people. I know the description says to clean every 75k miles. I don't know if i would try that, but i’m sure these filters can last quite a long time! Overall, a great choice over OEM if you don’t mind cleaning it yourself every once in a while.

I would not recommend it to a friend, I bought it to use it for taking shots of the ocean against the rocks, well when I place it to Max it does not close the whole disc black but does a star shape so that in the picture the corners are blown out and it gives a lot of cross-polarization. I was told it is common when you buy variable density filters that are not fixed. I just bought and received the Image ND 2 4 6 replacement filter kit and worked much better for me for what I was trying to accomplish. updated - Oct 27th - I am told that to use this filter it is best used at a 90 degree angle of the sun, that is you place your sholder facing the sun then stick your arm out in front of you at that in 90 degrees to help with flare and cross-polarization.

Now these are speakers! Out in the hot Texas sun and not even a whimper! You have options for mounting these speakers. Table top, staked in the ground (included) or hang them up. The sound is great and you have programmable lights. Once the speakers sinc up they will sinc the light show to. Worth the price

I use a uv filter to protect the lens, but sometimes you get glaring if pointed near the sun as expected as they all do unless its coated. Good lens.

I bought this filter to use in bright sun light with flash without always having to use hss.

Out of the gate the first thing you’ll notice is the build quality on this filter. It it feels really solid in your hand, there are no loose parts and has a good weight to it. I like how it has little grip extenders that you can grab a hold of to turn the filter. As the filter does need a little bit of pressure to turn it, it’s nice to have these so your fingers don’t slip. I like how it has hard stops on the ND filter so you don’t accidentally turn it too far, which can mess up your image really quick regardless of what brand filter you’re using.

There isn't a whole lot to say about this filter, it's just perfect for what it is - and an incredible bargain...I needed a protective filter, 77mm diameter and I took a chance on this from Vivitar. - The one thing I can do with any filter is check if it is "flat" and I do that by making "sun spots" - reflecting the sun into some shadow area as far away as I reasonably can, onto some plain, light wall or whatever and I want to see a circular and symmetrical "fuss-ball" with no "funny artifacts" and that's what I got...from both sides of the glass...so it's a "quick'n'dirty" check for flatness...But the best test - and the reason I got this second filter from Vivitar - was some shots taken with the full moon as light source of a scenery that included many bright street lights, with a very wide angle lens...if there were problems - this is where they should have presented themselves, but there were none. Both lens and this filter performed perfectly - no glares or reflection where you really could have expected some...so, there is nothing to complain about.Add to that that the metal ring, holding the glass is very thin, yet solid and well made and you've got "Five Stars"....
