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.

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!

I purchased the recommended 42mm size for my Canon 9xMK II camera. Followed directions and successfully mounted the supplied adhesive metal ring (AMR) on the camera lens barrel. I then reinserted the camera battery and everything worked OK. Put the camera away and did not use it for about 2 weeks. When I next turned the camera on I got a “Lens Error, Restart Camera. Camera will turn itself off” or something to that effect. The lens would not extend at all. Checked on the Internet for solution and was successful in getting it resolved – most likely cause mentioned is dirt or sand in the lens mechanism, or having dropped the camera. NONE of these was the cause in my case – the camera was put into a padded case and sat on the self until I went to use it again. The cause was the AMR I had installed. The outside diameter of the supplied AMR is slightly larger than the OD of the portion of the lens barrel it mounts to. As previously mentioned, when originally checking the camera operation during initial installation of the AMR, everything worked perfectly. During the time the camera was NOT in use, the small portion of the AMR that overhung the end section of the lens, took a “set” on the next portion of the lens (the lens telescopes in and out of the camera body). Once this "set" occurred, the camera could not overcome the force of the AMR at the end of the lens holding it to the next section – preventing the telescoping action. GET THE LENS TO OPEN. To free my stuck lens I repeatedly tapped the side of the camera body against a table while simultaneously turning on the camera. After many repetitions, the lens did open. This was only 1 of 7 suggested cures for a stuck lens, but none of the others worked for me. There is a caution attached to this suggestion, as it could further damage the camera. My PREVENTIVE CURE. Once satisfied with the placement of the AMR on your camera, check to see if the AMR overhangs the end section of the lens when the lens is extended (mine did have an overhang). If so, very carefully remove any of the exposed adhesive, being particularly careful not to allow any of it to remain on the side of the lens barrel – as there is virtually no clearance between sliding lens barrel sections and it will surely jam if any small bits of adhesive residue are left in place and the lens is retraced. Follow the method suggested in the instructions – remove the battery – to prevent the lens from retracting while you are working on it. Be advised: these were the steps that worked for me - use your own discretion when taking any action with your own equipment as it is possible to cause harm to yourself or your equipment.

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