Excellent professional quality, very easy to use and holds tight. No noticable color shift, just perfect for waterfall photos.

trust this brand and is great. I own several filters and I enjoy them so much. Great quality

Nice quality and easy to use, especially when I need to take it off faster.

This is my first magnetic filter and I think I may have to switch fully over to magnetic filters. I found that I like them. It makes since with a polarizer anyway. There is something satisfying with the snap when the the filter snaps into place. The polarizer does its job, adds contrast to the sky as you would expect. No moire or distortion, etc.

got this for my new Lumix S5ii. This is definitely a high-quality filter. It is well machined and has excellent optical quality. I've seen these filters sold at renowned photography stores. It does not disappoint. I really love the magnetic design.

I’ve hardly taken it off my camera since I tested it. I just loved it. I didn’t notice any color shift but the variable ND has been handy. The magnet is decent in my opinion. It’s the best I’ve seen as they all fall off at some point. This one only fell off when I was storing in my bad and had the lens cover on. It hit the case and fell off. I snapped it back on and and it’s been in place since. I totally forgot that it’s magnetic till it fell off. I believe that’s a good report. I really can’t complain. It’s definitely a good product.

Having a lot of camera equipment such as strobe lights, key lights, speedlights, umbrella, lenses, extra batteries, tripods and many other things. Wow I can't believe I use so many things just to get the photos that I want. Adding lens filter on top of all these is just.... what a hassle.

This variable ND filter and magnetic adapter ring kit are one step in the right direction. It's very easy to put on the magnetic adapter ring kit. Once the ring kit is secured, attaching the variable ND filter is very easy. It's a convenience that this filter god from ND2 - N32, 5 stops.

Hint: Make sure you pick the right filter size. If you have a collection of lenses with varying sizes, pick a higher size. You can buy a separate adapter to downsize.

I'm an amateur at photography and decided to try out this lens. I like that you can adjust the lighting and darkening of the lens. I love the magnetic feature.

This filter has 5 stops varies the density as per light intensity required. Overall quality is great and it is a good product to carry for the photoshoots.

I come with a long history of taking photographs with filters for special effects. I have used Cokin systems where you can share one filter with various lenses with adapters. I own over 50 such filters and lately, I am simplifying my camera bag and traveling with only a few filters. My most popular filters are the graduated neutral density (ND) filters. With these, I can rotate the filter to my preference on each shot. BUT that means I have to carry more than a few of the same ND filter but at different stops.

Solution: The K&F Concept Magnetic Variable ND Filter offers me an option to use one filter covering 5 stops within seconds. That is great timesaver as my shots of landscapes or sunsets sometimes requires swift framing and adjusting to rapid light changes.

ND filters are an investment to your camera gear. These will filter out very bright light and allows the photographer longer exposures during daylight. My favorite use of ND filters is to have water movements look silky while capturing the surrounding in detail. This K&F Concept filter is built amazingly well. The glass is better than my Cokins. Since it is built to specific lens size diameters, I had to rationalize which lens I used the most and ordered that size. 58mm in this case.

The case is a worthy vault for this filter. Kudos to the team that designed that feature. The magnetic ring screwed nicely into my existing lens. In fact, it screwed in too tightly, it took me 10 long minutes trying to unscrew it later on.

The magic is with the magnetic technology. Wow! It was instant on and instant off for the actual ND filter. Amazing. With that also comes the fear of dropping the filter. I fear that a bump will dislodge it so I kept my hand on the lens at all time. If you are in stationary setting, you should be fine.

This lens filter is a great tool for many future vacation shoots. Simple to carry and use.

Do note you cannot place a regular lens cap over the ND filter. Bummer.

Overall, I love the new direction that these ND Filters are headed. It is less fuss and more time spent on the actual shooting pictures. Give this a try. I do recommend this variable ND filter. 4.5 stars.
