This product was sent to me for review, as part of Amazon Vine. The below is my own real-world experience of using it.

I was drawn to it, because I occasionally like to shoot wildlife videos with my iPhone 15 Pro Max, and thought that the filter would be most helpful during very sunny days.

The kit is comprehensive - you are getting the magnetic filter attachment, the filter, a cleaning cloth and an exceptionally good-quality case to store everything inside. This itself is compact, so would easily fit inside a small bag.

I have mixed feelings about some of the components - the main filter attachment is robust, but doesn't fit well over a case. The one I use is not the thickest, but it was enough to impede the attachment from lining up properly with my phone's lenses. I also don't like the screw clamp - the idea of putting pressure on my phone's screen makes me uncomfortable, especially because you can tighten the screw quite a bit. The magnet works fairly well to hold the filter, though it didn't seem like it had the strongest of holds, so I am unsure for how long the filter could reasonably be held in place, particularly if you are moving around a lot in the field.

Despite the above, the filter itself does make a difference in harsh light, though I would recommend checking some settings first - I didn't realise that my flash was set to 'auto', so it fired underneath the filter, and washed my first attempt at a picture out (the flash is obscured underneath the filter, so the light is bounced back).

Overall, it is a nice kit, but could be improved.

I use a Fujifilm X-T3 camera and have this to match my 55-200mm zoom lens. The mounting ring attaches easily to the lens and I'm a big fan of the magnetic attachment for this filter. There are many different brands of diffusion filters. I have used Tiffen brand filters in the past and have always been happy with them, but when I came across the K&F filters I was dying to try them.

I have used K&F products in the past and have been particularly pleased with their lens adapter system (I used to shoot with Pentax cameras and lenses and their excellent lens adapter has enabled me to use my old Pentax lenses with my Fujifilm camera.

This magnet system does not disappoint. Replacing the filters is very easy with the magnetic attachment system. The lens cap for the filter system has been criticized by some but I think it works very well. It actually reminds me of some lens caps on my Pentax system, so I felt very comfortable with them.

As for the quality of the diffusion - excellent! I really enjoy the softer look this diffusion delivers without being too heavy.

However, one thing surprised me a bit. I expected to be able to install this filter system and then still use my tulip shaped lens hood, but I can't do that with this K&F attached to my lens. To be honest I wouldn't be surprised if that really is the Fujifilm system's fault as I've found the lens hoods to be difficult to attach compared to other camera systems I've used in the past. That said, I intend to purchase more K&F brand ND filters to take full advantage of this magnetic attachment system. It's a winner in my book.

I finally found a tripod with a built in monopod to replace my selfie stick. With the Pentax you can from a height of approx. with the remote control. What's also important to me is the camera's smooth, shake-free panning for capturing wildlife and landscapes. Works very well. Thanks to the ball joint, the Pentax can be adjusted and locked in any position in no time at all. And thanks to the rotating center post, the camera can stay a few millimeters above ground when shooting without me having to lie in the mud or touch the DSLR. The materials used make a very good impression on me.

Perfect for using my old lens on my new Pentax!

I like that you can turn the backlight off on this. I also like that you can turn Off the alarm for high c02. It uses a usb-C charger which is a nice addition.

Item came packaged like an apple product and it is easy to use.

Well built adapter, it fits perfectly with recent and older Pentax camera bodies. Compared to another adapter in my possession I find it easier to attach. I advise

I have had the camera out for about 3 weeks now. It’s working great and takes great pictures both day and night. The flash is surprisingly bright with a handy screen to check pictures on this camera.
