Kamerar MagFilter 44mm Circular Polarizer Filter (CPL) with Carrier Bag for Compact Camera, Sony RX 100 IV, V VI, VII, Canon Canon G5X Mark I II G7X Mark I II III G9X, Nikon, and Panasonic

This is my 2nd MagFilter....lost the 1st somewhere, putting in and out of camera pouch on my backpack. Best to store in the MagFilter pouch that comes with the product. To improve the security of the MagFilter pouch, I added a couple of Velcro dots/coins (photo) to hold the flap closed. The adhesive rings are easy to install, wiping the lens surface with alcohol first, then centering the rings and pressing to finish. The rings are a perfect fit for my Sony RX-100-M7, Lumix DC-ZS70, and my Canon G15. So one CPL can do duty on 3 cameras. The CPL tested out to be circular polarizer. LCD displays emit linearly polarized light. Take a look at an LCD display through your polarizer and rotate it. Then look through the other side of the CPL at the LCD screen. It will dim/brighten as you rotate looking through the one direction, and will not dim when looking through the CPL in the other direction. This feature will insure the polarized light will not interfere with the camera's focus and metering. The box say the MagFilter is made in China, but the CPL clearly has made in Japan etched. This is a quality product, and the clever magnetic designs allows the CPL to be easily used on multiple cameras. Just be careful keeping it on the lens, and putting the camera in and out of the camera pouch. The magnet is reasonable strong, but will not hold the CPL if brushed against the pouch.

This is awesome. Adding a polarizer to the RX100 VII makes it so much more versatile. I wish all of my lenses had this. Swapping the filter on and off is almost instant and the magnet feels very secure. I use my camera at the beach a lot and now I don't have to worry about sad ruining my filter threads. Great inventive product!

This is a great product, as long as at the adhesive metal ring stays in place. I have had to use the second adhesive ring now within a month. I would still buy it again (as I already have), as it offers great protection from dust especially as I use it in a dusty place like Nigeria. The magnetic strength is adequate and the lens does not impact picture quality or lens operation. The next few months will be rough on the camera as it will be heading to the Arabian desert, let's hope it holds up and provides the much needed protection.

Wow, finally a polarizer that fits my pocket camera! I do a lot of shooting with my DSLR, but there are times I can't take all my gear. So I have a Sony DSC-RX100, an advanced pocket camera that has all the same creative and manual controls that my big camera has. But, no filter attachments. I can simulate most effects in Photoshop if I need to, but you can't simulate a polarizer, and you can't get the same clarity and deep color in daylight without it. This works great. The magnetic ring stays securely on my lens, and the filter pops on and off easier than a traditional threaded ring. It holds secure. One thing- it came with two rings and no instructions. I thought at first one was for the camera and the other for the filter. But, you just apply one to the lens and the other is, I assume, a spare. Some reviewers said the filter will fall out of the supplied pouch. I don't see how that's possible if used correctly. The pouch has a top flap that overlaps the slot, you just have to make sure it's pulled over the opening, it holds securely.

Soooo glad I purchased this filter because it protected my NEW camera's lens from ugly/expensive damage!!! Allow me to explain. A few months ago, I purchased a brand new Canon G7X Mark II camera and a MagFilter 42mm CPL (Circular Polarizer) Filter. I wanted the 42mm because the edges do not show in photos and videos. As a recipe developer/food blogger, I take food photos and film recipe videos for my blog, www.CornbreadMillionaire.com. Since 2014, I've used a Canon PowerShot A1100 IS and it still works GREAT. However, it was time to upgrade. I LOVE Canon so I purchased the super popular G7X MARK II. Whenever I use my G7X camera, I ALWAYS make sure the filter is on to protect the lens. WISE DECISION! Two weeks ago, I was in the kitchen working on my Green Sauce recipe and had a little accident. My new G7X Mark II camera accidentally fell "lens first" into the bowl of Green Sauce. I snatched it out before it was totally submerged and carefully cleaned the camera and filter... before removing the filter. The tightly secured filter protected the camera's lens. NOT one drop of sauce touched the lens. The sauce did not penetrate the camera either. In fact, my camera is in EXCELLENT CONDITION!! It still takes clear photos and clear videos. Hallelujah!! I could not get the filter cleaned properly so I ordered a new one. No problem. Much better than spending $600 to purchase a new G7X Mark II!!! I highly recommend purchasing this filter to protect the lens of your camera.

The quality of the polarizer seems decent. They include the carrying case and two magnetic rings. I did not need to use the magnetic rings, so not sure how well they hold up. I slapped this filter onto a Street Guardian sgzc12sg and it fit pretty close to perfect. Considering this is a CPL with a magnetic attachment, I think the price is fair. What can I say, it gets the job done!

I am so bummed. I was so excited to go out and use this filter on my new camera when I went for my hike. I thought it was supposed to stay on the camera but when we got done and I took the camera out of the bag I bought for it, the filter was gone. I can't even rate it since I never got to use it because apparently it fell off and dropped when I took it out to take a picture. Great idea but it didn't work for me. The ring stayed on the camera but the filter was gone!

Bought this mainly to protect the lens of my Canon G7X mark 2 retractable lens but was pleasantly suprised at how well this lens works also in bright daylight. It's magnet sticks tight enough where I haven't seen it drop off my camera yet but will fall off with rough, sudden movement still. I leave it on the camera at all times as an extra layer of dust and protection for the lens since it fits snugly on my camera still. Very satisfied with this filter. Shipped fast and priced right too.

Great product delivery was earlier than expected. Left at front door without knocking.

However, the product would be a great addition to any camera. Warning: You will have to pay return fees, which might or might not be fully refundable.

Fits on strong and no dark corners
