This K&F Concept Clip-On 67mm CPL Magnetic Phone Lens Filter Kit is very easy to use and fits over my iPhone camera perfectly. However, it may not work for other phones with different camera configurations. The filter does help significantly reduce harsh reflections, but I’m not very impressed with its ability to deepen and enrich blue skies. It comes in a nice protective case with a microfiber lens wipe as well. Unfortunately, this is not a rotating circular polarizer like the ones they make for DSLR cameras. On the plus side, it does have a magnetic mount, so it’s easy to adjust and swap out with other filters as needed.

Great quality and fits my iPhone 14 pro.

I got this to keep in my car for when I need a tripod in a pinch, even for my iPhone (it comes with a phone mount adapter). It's plenty sturdy even for a DSLR with a heavy lens. I think it will serve me well in the field.

I ordered the magnetic phone camera lens kit for my iPhone because I like to take videos and photos. The product quality is very high and it is easy to install.

The kit works exactly as expected and delivers much better results. I can only recommend it.

This adapter opens the lens of my Leica camera with a Canon lens

It is a manual lens adapter.

The product meets my needs to serve as an adapter from a Nikon lens to my Canon camera. The only problem has been that I had to do a lot of research to make sure the lens worked. In the product description they are not too specific. Otherwise perfect and received within 12 hours of ordering

The adapter can be easily used on both the camera (450D) and the lens (Tessar 4/135 from CZJ). The lens is about 60 years old and I was curious to see if it would still be possible to take pictures with it. This can be confirmed with "yes". Of course you have to do without automatic functions, you can only do it with manual exposure and focus adjustment, as it used to be. As far as the connection to the camera or lens, which has been mentioned several times, cannot be separated again, minimal lubrication BEFORE first use is announced and solves this "problem" before it arises.
