Reduces reflections magically and really does sharpen colors. I definitely recommend this. The only problem is that, if you normally like to manually focus, you have to switch the lens to automatic focus before adjusting the polarizer or else you'll lose your focus! Turning the polarizer will also turn the focus unless it's in the automatic function.*it is very hard to take off your lens though. and you cannot tighten it loosely or else it'll unscrew as you turn the polarizer so you kind of have to tighten it onto your lens all the way

Ok, so I ordered this to replace an aging Bushnell trail cam that was SD only, no telemetry. This cost about the same as my old can, but had a few additional features that I thought would be helpful. There is an app I can use on my phone which allows me to connect to the camera via a wifi connection. To save the batteries (8 x AAs) you can turn the wifi connection on and off using the wrist mounted remote. Little complaint here, the buckle orientation is reversed. The app isn’t the most user friendly, but you can’t beat it for the price. Anything comparative by the big brand names will be well over $200. This was WELL below that! I took it up to the mountains recently to test it and used my daughter to trigger it. I was also able to use it remotely and view the camera feed from my phone. While hunting, this will let me see the deer coming my way or let me know if they have changed direction. I have yet to test all of the features of the app, so I don’t know yet If I will get alerts when the camera is triggered, but it has already proven its usefulness and utility as a trail camera.

This is a good adjustable neutral density filter with no problems I can see. It uses K&F's special coatings to help repel dust, water and fingerprints. This filter has a magnetic attachment system, there is a magnetic ring (with no glass in it) you screw onto your lens. Then whenever you want to use the ND filter you just pop it on and pull it off magnetically, making it easy to change. The system seems to work well, but it's the only one of their filters I have which features it. By rotating the filter you can go from ND2 to ND32, or 1-5 stops.A lot of people wonder what this kind of filter is for, basically it lets you get some different effects when you are shooting in direct sunlight. For example, you can open the F-Stop of your lens all the way to get a shallow depth of field effect, then use the ND filter to darken the image back down so it is exposed right. Another common use is so you can shoot with longer shutter speeds in bright light. This will allow you to get that effect where moving water has a soft motion blur on it by setting a longer shutter speed and adjusting the exposure with the filter. It's also very handy for shooting video in bright light. Using a high F-stop and shutter speed for this can give you a video that has no motion blur and appears to stutter when the camera pans. The ND filter can allow you to shoot with longer exposures which will give motion blur and a smoother more cinematic look when panning.So overall a very useful filter to have if you do videos or photos outdoors in bright sunlight.

Used it right out of the box and it was amazing! Great picture and easy to use.
