I use a Nikon D3100, I bought a Nikon 50mm f/1.8D AF Nikkor Lens. That lens has 58mm threads. I bought the 58mm Tiffen Circular Polarizer filter to use on that lens. At the time of my order it was sold and fulfilled by Amazon. I paid for shipping and received the filter in less than four days. The filter came in a hard plastic box that I use for storing the filter. It looked new and works fine. No filter problems and I give it 5 stars. The only issue is screwing it onto the lens is a bit tricky because you only have half the width to work with but I blame that on my fingers and lack of any real nails. I have noticed that if the filter doesn't go on straight it may make a glare effect but when I see that, I rescrew it on and that takes care of the issue.

The is one of my best photography gadget purchases in decades. It's brilliant design and engineering. I use it attached to a Powerextra Utility Outdoor Photography Adjustable Waist Strap Belt and it keeps one of my camera body and lenses handy for a quick switch. I also ordered an extra Peak Design Standard Plate to attach a second camera body and lenses combo to swap out with the one on the belt.

So far this circular polarizer works with excellent results.

As a photographer this product is good for the price it really does what its suppose to do I can tell how different my photos look with and without the polarizer.

Ottimo tutto migliorata in tutto ma la lente fissa non sono d’accordo!!!Gopro fatto un passo in dietro per questo motivo..!!Poi che non ha più la scocca di protezione è ancora un difetto che la devi comprare a parte..!

Works just as stated. Solid design and construction. Easy to use

this little camera does a lot for the price. good quality video, underwater shooting, time lapse, loop and slow motion. It does all of that fairly well, quite well for the money. audio is the downside, plus no audio input receptacle to add your own mic. so, a grade of A+ for price, a solid A for video, and a D for audio. Think of this as a secondary camera for video, and use another audio source.
