Bought this to add to the original ND/polarizer kit by K&F. 10 stops, no color cast and excellent quality

Quality is superb, been using K&F products for years. Once the lens cap is seated, it’s difficult but not a problem with its removal. That’s my Pentax 6x7 with the K&F magnetic lens cap. While hiking up Koko Head Stairs, the lens cap remained as I had my camera out, taking photos of the climb up. It’s a worthy purchase. I’ll be buying more of these soon for my other lenses too.

No color casting, strong magnets, very durable, nice protective case, great filter from K&F Buy them all.

I am now using all my filters far more because it's so easy to put on and take off.
I have the CPL and ND 10 and a UV so the system works on my 3 main lenses.
Picture quality seems perfect to my eyes.

As someone who frequently dabbles in landscape and long-exposure photography, I recently decided to invest in the K&F Concept 77mm Magnetic ND1000 Lens Filter, and I’m thrilled with the results.

The ND1000 filter provides a 10-stop reduction in light, which is perfect for long-exposure photography. I’ve used it for capturing smooth, flowing water in waterfalls and streams, and it has consistently delivered stunning results. The filter effectively reduces glare and helps achieve the silky-smooth effect I was aiming for, without introducing any noticeable color shifts or distortions. The image quality remains sharp and clear, which is crucial for maintaining the integrity of my shots.

Ease of Use:
One of the standout features of this filter is its magnetic attachment system. It’s incredibly user-friendly—just snap it onto the lens, and you’re good to go. This system not only simplifies the process but also minimizes the risk of cross-threading or damaging the filter threads on the lens. Additionally, the included magnetic lens cap is a thoughtful touch, ensuring that the filter remains protected when not in use.

Lthe lens filter has exceeded my expectations in every regard. Its innovative magnetic design makes it incredibly easy to use, and its performance in terms of light reduction and image quality is top-notch. For anyone looking to enhance their long-exposure photography or manage bright conditions more effectively, this filter is a fantastic investment. It has quickly become a staple in my photography gear collection, and I highly recommend it to fellow photographers.

At the second time of ordering this item, it arrived. It was a replacement for the one I lost from the set. What I am pleased with is the magnetic lens cap! It is so easy to put on and take off. K&F quality is always good. The magnetic lens system is the absolute best for me, the lens quality is good. I am very satisfied.

This format stacks with the magnet, although they don't work with non magnetic filter

The quick magnetic feature is good. Allows you to set up, work out new timing etc then pop the filter on immediately before taking the photo.

My one criticism? I wish you could buy other magnetic filters individually rather than another set with another magnetic ring, another cover etc.

If you use the screw type ND filters for long exposure photography do yourself a favor and get these magnetic filters. The ease of being able to quickly remove the filter to meter, focus, and compose your shot then put the filter on and take your shot is well worth replacing your screw on filters. This filter is of very acceptable quality both build and image wise. There's a slight warmth to them, but can be fixed in post if you like. I bought this ND1000 and a separate K&F set that includes the CPL and that pretty much covers the filters I use most. I'm really happy with K&F filters.

I looked at a lot of different magnetic filter systems, but ultimately decided on the K&F filters. It was a great decision. I would have purchased from their new Pro lineup, but they weren't available at the time (at least in magnetic form).

Stacking the magnetic filters works perfectly as well, as the magnets are strong enough to keep everything in place and stable.

With a 24mm lens (and the 82mm filters), there is some vignetting in the corners, but zooming in a bit or cropping in post deals with that. I suspect the Pro lineup resolves this issue. All in all, these were far less expensive and yet more convenient than the other systems I looked at. I highly recommend them.
