This filter has changed the way that I do photography! When I pair this with my f/1.8 prime lens, I can get amazing depth of field shots in broad daylight without having them being blown out or overexposed. This made for some great Senior photos. And, I can take some great long-exposure shots during the daytime of waterfalls and things. I would definitely recommend this filter to any photographer looking to accomplish these things.There are a couple of drawbacks to this filter however. If you want to use this filter in combination with others such as a UV filter, this needs to be the filter on top. The mount on the top of this filter (not the side that attaches to the camera) is 55MM rather than 52MM. This means that with this filter on, I cannot attach my lens cap or any other filter. I ended up putting my UV filter onto the camera first, so it's not a big deal. The only other thing is that the arrow indicating what level of ND is being applied is on the bottom of the filter, so I have to flip up my camera to check where I'm at. I saw other reviewers commenting this as well.Overall, I like using this filter and I have gotten some great shots with it. Would recommend to any amateur photographer looking to step up their game.

Great action movie! One of the classics that you must see!

 The quality of pictures and videos that the YI 4K Action Camera take are really amazing for such a small little camera.* The options seam to be limitless of what this camera can do* Still photos are amazing* I did several time-lapse videos, slow-motion videos and regular videos, all of which I am very happy with.* Screen clarity is bright and clear* The battery/SD card door is easy to access and get your battery or SD card out.* I bought a Bluetooth remote and was disappointed in its performance. I found that it took nearly 30-45 seconds to be operational every time I turned the camera back on and wanted to use it. I found that downloading the android app was just as useful and actually gave you so many more options.* I bought several aftermarket accessories that work with other action cameras and they all worked without a hitch.**I took off one star because the camera by itself is not very durable as far as the case goes. The case is made of plastic and scratches very easily. Just taking it in and out of my bag while on a selfie stick got it dinged up pretty good. The screen is find and the lens gets really dirty with dust. The case needs to be made out of something other than the plastic case it currently is made out of. Also a lens cover would be very helpful in keeping the lens clean and protected.Overall I would and have recommended the YI 4K Action Camera to friends and family. When compared to the other cameras on the market this is hands down the way to go for overall best bang for the buck with lots of change to spare.

This is a nice little Action Camera for the price that is pretty good out of the box. I bought this action camera for some planned water activities during a family vacation in Mexico, unfortunately the sargassum seaweed was still pretty heavy and limited our water activity to paddle boarding. I haven’t had a chance to really experiment with it but the video with was really clear and captured some funny moments.There are a lot of accessories that come with the camera, it would have been nice if it included the most common selfie stick and a lens cover for the camera. While it comes with a waterproof case that it can be stored in it would be nice to not have to carry that all the time to protect the lens.

Great value. Pictures look good with filter. Provides camera lens protection. Lens cap fit with filter on.

I was looking at action cameras when this little jewel showed up as a Best Buy at 42% off the price and had 23,000+ ratings. After reading a few of the reviews I figured at the price what could I loose. The project I was getting it for was to begin to document a sailboat racing the next weekend. I'd gotten a Movavi Video Editing suite the week before and needed a camera to supply B Roll. This camera was so easy to set up and operate. Transfer to the computer was straight forward. The images were clear and sharp. I got a hand hold that floats because I'm not stupid. I was blown away and probably sold a half dozen at the yacht club this past Saturday. Now I will be getting a Akaso V50X because of the video stabilization and 4 lens zoom. This will replace the EK7000 on the chase boat. We will mount the EK7000 on the cabin top. The 170 degree lens will work perfectly to catch all the action in the cockpit. There is no downside with Akaso, they deliver.

I have been using this filter to protect my lens and it has done the job.

This filter acts a protection cover for my camera's lens.
