Excellent ND filters for the DJI Mavic 3 Classic.
I was excited to see this set of ND filters from K&F Concept. K&F is a very good company with a great reputation for high quality photo products, especially lenses and filters. The question of whether or not to get ND filters for a drone should be a non-issue. Without any trees and buildings filtering out some of the direct sunlight, you really need ND filters in order to get a good exposure. I think the 4 filter set that K&F put together here is a perfect beginning set; ND8 (3 stops), ND16 (4 stops), ND32 (5 stops), and ND64 (6 stops). Depending on your use and where you live, you may want to get higher and/or lower stops. I certainly plan on getting some more.In my area, it seems I have either water, snow or clouds that want to wash out my videos and photos. Even when it is overcast, which is frequent, I need something to get the details out of the sky. After many days of uncooperative weather, I was finally able to get some sample photos for my review. I tried to get photos of the sky without a filter and then with each of the 4 ND filters. But, I can't guarantee they will appear in the correct order that I uploaded them. So it may be impossible to determine which photo has which filter. Sorry...My only complaint and the reason for my review score, is they were an absolute pain to put on. It seems like the tabs that are supposed to fit into the locking slot is larger on these filters than the original manufacture's lens shield. When I looked at them side by side they appear minutely larger. As I tried putting them on, I thought I was going to damage the DJI lens housing, break a tab, or bend the slot it is supposed to fit into. The original DJI lens housing fits on snugly, but securely. These just fit on terribly hard. I think DJI is partly to blame. It seems like it would be easier for them to make the lenses so 3rd parties could make accessories that fit easier and securely (i.e., round threaded filter instead of square).In spite of that, these filters are very well made of high quality glass and materials, which is the most important thing for a lens filter. As the description says they are very light, nanometer coated, anti-glare, and waterproof and dust-proof. These will certainly be used a lot and I hope to see K&F adopt more of their lenses for the DJI Mavic 3 Classic. Please, just make the filters easier to put on. ;-)
