I didn’t like that you can’t connect a wireless microphone but everything else is fine

The Boya Omic Wireless Mic is an impressive and cost-effective option that continually improves over time, now featuring a convenient charging case and significant sound enhancements. Compatible with computers, Android/iOS devices, and more, it's perfect for content creation, live streaming, Vlog filming, and mobile journalism. With outstanding sound quality, adjustable noise reduction, and an impressive wireless range of up to 50 meters, it ensures clear audio and flexibility. The portable system also has built-in rechargeable battery with up to 5 hours of runtime, extendable to 20 hours with the charging case, which supports wireless charging for added convenience.

I bought the K&F magnetic CPL filter to mount on a Sony 18-105 lens. Although the filter is excellently made (even the magnet attaches well to the support ring), the main problem is that the lens cap (72mm diameter) does not attach to either the filter or the support ring, leaving the glasses unprotected. The return has begun.

Simple to mount, the magnetic filter ring attaches to the metal holder ring (which is attached with a clamp that goes across the top of the phone). Various filters are available, including ND (neutral density) and CPL (circular polarising). I used the CPL and found it very effective. Of course, with most modern phones, you can adjust image parameters post-capture but I am old school and prefer to get the image right first, so this is ideal to achieve a fine polarised effect. This item can be strongly recommended. Well designed with good quality materials.

The idea of a magnetic filter system is very good, in the set you get the mount, circular polarizer, UV filter and an ND1000 filter all inside a nice quality pouch to keep them safe. This set is ideal for the landscape photographers out there, the ND filter allows you to slow down the shutter speed to enhance the effect of movement, the circular polarizer allows the control of reflections. Overall a very handy set that will be a permenant part of my kit.

I haven't used any magnetic mount filters before. It's really nice to have that. I didn't realize how convenient it would be not to have to screw and unscrew filters every time I want to make a change.

The diffusion effect of this lens is easy to notice if you're looking for it, but subtle enough that it doesn't call attention to itself. I was concerned that it might be too much at first, but I like the results. I didn't notice any color cast either. Very nice filter. Does the job well.

Magnetic Filter Attachment, quick and easy to attach or remove from the camera lens.
THe 1/4 Black Mist filter is fantastic and definitely one of my favorites. The Filter comes with 3 items

1) The Filter Ring that threads on to the lens end
2) The Magnetic filter
3) Magnetic Filter Lens Cap.

Common Question(s):
Can you use the canon lens cap with the Magnetic ring installed (YES)
Can you use the Canon lens cap with the magnetic Filter in place (YES)
Can you use the Lens Cap with the magnetic base without the filter magnetically attached (YES)

Overall, really good quality lens and it is a breeze to install. The Magnetism is strong and the lens cap does not fall off nor does the filter. It has just the right amount of magnetism to keep everything in place.
Very Good Lens and Concept for mounting it to the camera.

The filters appear to work well in testing. I would not trust them to remain on the camera when in the field. The magnetic mount is not strong enough. Fine for tripod use and then take the filters off and put them back in their case.
