Magnetic filter from the well-known brand K&F, which has been offering high-quality photographic filters at a very competitive price for several years. I've been using a 72mm K&F magnetic filter kit for almost two years now, consisting of UV, CPL, ND64, and ND1000 filters, which I'm delighted with. Not only because of the magnetic filter inserts, which make them much faster to insert and remove, but also because of the possibility of using a magnetic cap. In this case, we have a UV filter that, in addition to being magnetic, also has a thread for direct mounting on the lens. A very interesting detail for those who opt for this filter and don't yet have the magnetic system. Or it's also an advantage that it has a thread in case you have two lenses with the same thread, but only one of them has a magnetic adapter. In terms of quality, there's nothing to object to; it's made of aluminum with very good finishes, and the glass emits some shades when held up to the light, indicating some type of coating, so it's not just simple transparent glass. I don't usually use these types of UV filters, but I occasionally use them when taking pictures in dusty, windy environments or when it's raining. When it's raining and you have to keep cleaning the lens, using this filter risks scratching the filter but not the front element of the lens. In short, a quality filter with the advantage of being magnetic, making it a very good option for anyone looking to expand their K&F magnetic filter kit. A very nice detail, and a great success that K&F offers the option to purchase filters individually and doesn't require you to buy complete kits.
