Magnetic filters are just plain awesome, especially when they include a magnetic lens cap. K&F concept's 1/4 black soft diffusion filter provides a hefty dose of the 'CineBloom' effect in a magnetic, quick-swap system that includes a lens cap.

Installation is simple and begins with installing the threaded magnetic ring adapter. Once the magnetic adapter is installed, the filter is attached via magnetic attraction, as is the lens cap afterwards.

The filter looks great, with zero distortion or color shift. These are pretty slim so I didn't experience any issues with vignetting.

The reason I took off a star is that the lens cap is fairly difficult to remove. The magnetic forces are ridiculously strong, too much so. Removing the lens cap is difficult, an I usually end up having to use so much force that I end up running a finger across the lens once the lens cap finally budges.

Other than that, its another quality filter kit from K&F concepts. Buy with confidence.

The microscope itself is amazing and with all the correct pieces and software, you can do some awesome things. The only reason I didn't give it 5 stars is because it came with a disk instead of a link to download the software to use the eyepiece. And the instructions didn't really give good instructions on how to set it up. But they did state in the instructions to email them if you can't use the disk. When I emailed they were very responsive. The first link they sent didn't work but they provided other options based off if I had a Mac or PC and they gave me the correct software for my Mac and it worked. It took a while to position it correctly though to actually see something on my screen but I figured that out as I kept playing with it. The instructions weren't that great but the product itself was well worth the investment.

Hello,
It's a very good quality ratio for this K&F magnetic filter.
I recommend it.

Bought it for kids, it's easy to use and if you connect it to a Mac you can also view and record photos and videos. Good tool for kids to explore the micro world.

Human sick easy when not good Air. This is perfect indoor monitor for air which you can control ion your house and reset or clean it. it also smart so connect your phone and humidifier so you can control air.

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.
