Advantages1. The camera is small and can be carried easily.2. The battery usage time is long.3. Easy to select menu.4. It is waterproof.6. The price/performance is good.Disadvantages1. In 1080 60fps shooting, the pixels are coarse than expected, and the sharpness of the screen is poor. 2. The zoom function is meaningless because it is not an optical zoom. Conclusion: Good for beginners to use.(After using more, I will add a testimony.)

The K&F Concept Magnetic 62mm Lens ND Filters Kit (5 Pack) GND8+ND8+ND64+ND1000 + Magnetic Filter Adapter Ring Filters Set with 28 Multi-Coated for Camera Lens:

This is an outstanding ND filter kit. The filters themselves are very good ND filters with no color shift. I have been using several K&F Concept filters lately and I find them to be among some of the best I’ve ever used. Overall very well engineered and constructed. This kit comes with 3 levels of neutral density and 1 graduated ND. The filters attach magnetically to a screw in ring, making swapping them out quick and easy. The magnetic ring is pre attached to one of the filters when the kit arrives, and you will use that one ring for all 4 filters. I really love the addition of the gradient ND as landscapes are one of my passions and this filter is ideal for bringing drama out of the sky. The kit also comes in a very nice filter wallet with several ways to attach it to your bag, belt, tripod etc. This is such a nice touch, and it really is a nice wallet, not just a cheap holder. I highly recommend this kit if you are looking for high quality ND filters. If you love to shoot very shallow and wide open, these are a must have. Solid color rendition, well designed and well made, high end filters.

These are so easy to use and the quality is fantastic - both the build quality and the picture quality. I can't see any colour cast whatsoever from both the CPL & ND filter. I think you would really need to pixel peep to see any sharpness difference, and even then I'm not sure there is.
Being able to attach the filters to both the UV filter and filter ring is really clever - I keep the UV on my 24-70 F4 and the filter thread ring on 16-35 F4 so it makes it even faster to clip on the filters no matter what lens I use.
Since the ND isn't variable, there's no dark X. And no vignetting at 16mm, unlike when I use my square filter set.

The downsides that I see at the moment:
- You can't replace the filter thread on its own, so if you break or lose it, you have to buy a new set. I contacted support but was asked to pay $16 for delivery of a new thread....
- The range of NDs isn't as big as a square filter system (yet) and again I'm not sure if you can buy them as singles or whether it's just part of these kits

Works great on my Nikon Z6 16-30

Arrived quickly on 16-24 November. An interesting toy

It's better than some really cheap variable ND filters I got a few years ago.
