Hoya 67 mm Fusion Antistatic Protector Filter

I am a career professional photographer and every lens I own has an optically clear glass “filter” over the lens. If you want a really good one some might will run you about three times what this costs. An optically clear glass “filter” is not the same as a UV filter because it is not a filter at all, it doesn’t filter anything or affect the light transmission to the camera film or sensor. A UV filter by its nature does filter the light in some measurable way, which theoretically can affect your image. But maybe not really because 99% of camera owners never change the white balance settings from automatic, or may not even have settings to do that. So if a UV filter maker is telling you that it filters out a blue cast (for example), and again theoretically, your camera is probably going to correct that to achieve what it thinks is perfect white balance. WHAT IS THIS, REALLY The reason I buy a clear filter as soon as I buy a lens is not so much to protect my expensive lens from damage, although that is a side benefit, but because in the course of a day the surface of a lens gets dusty, there are inevitable fingerprints, raindrops, snow, etc which can affect image quality. And more so, constantly brushing and cleaning the surface of a lens can eventually scratch the coated surface. A piece of clear glass is just easier to clean. Look at the "with and without" photos below – the lens has a deep cavity in which dust and moisture WILL gather, not just on the lens but in the threads and every tiny crevice. With the protective glass filter that entire cavity is effectively sealed off leaving only the large flat surface exposed which has antistatic and anti-moisture properties and is easily cleaned, and in the very long term, can be replaced when and if necessary. I would guess that only about 2% of camera owners opt for clear glass, there seems to be an urban legend that drives them to want to own a UV filter. Personally I don’t like anything on my camera that can affect images in any way. WHY DID I BUY THIS ONE This was bought for my new personal Fujifilm X-T5 camera’s lens for the above reasons. I chose this one because Hoya is one of the most respected optical glass companies in the world, still making many of their products themselves in Japan. It’s a brand I have trusted since my early film days. It’s hard to find optically clear filters these days and you have to read the product descriptions very carefully, even this one, because as major of a brand this is, their page is very sparse in details and completely devoid of the breathless hype found on most other brand’s pages. This is a company who makes products for professionals who don’t need to see over-the-top ads. QUALITY There’s not a lot of first impression excitement either, their approach is simplicity and the filter itself is just what it is – moderately thin, well machined with precision threads and the glass is perfect. YES NO MAYBE Reviewing what I said above my goal was simple – a clear filter that would not in any way distort or color change my images, that would have near perfect light transmission. But the bottom line for me is I’m not expecting to put this on my camera to protect my lens from physical impact, no what’s highest on my list of priorities is that it should repel dust and water as much as technically possible and that’s Hoya’s biggest claim. I could have paid sixty bucks for the top name brand, and that would be okay with me, but I believe this one is functionally equal.

Hoya has been my go-to for multi-coated lens filters for many years, ever since I worked with their anti-reflective (AR) products on eyeglass lenses in a former career. Hoya has always lead this field, making some of the the best hydro/oleophobic and scratch resistant AR products available. This filter is no different, Hoya quality as expected. The AR multi-coating renders the lens nearly invisible when viewed head on, as it should, and the additional anti-static feature is great! You do pay a little extra for a Hoya brand filter, but it is a wise investment. I leave my UV filter on the lens full time for additional protection as I watched a friend ruin a $500 lens many years ago. I was new to photography and he always talked about using a good UV filter as a layer of protection on your lenses. He cursed himself for using that lens before his replacement UV filter had arrived to the camera shop, a true lesson in practice what you preach! Recently, I came across the K&F Concept Nano-X filters and have to say that they are giving Hoya a good run for the money. A comparable multi-coated UV filter from them is about $15 less, and as far as I can tell, they only difference may be the anti-static property being less than Hoya's. I will continue to put Hoya filters on my frequently used lenses, but K&F will probably find a home on those lesser used.

I have used UV filters on my camera lenses for decades, since they are a great way to keep the front glass clean and to protect it from scratches and breaks in the event of an accident. I've been using Hoya filters for a long time too. I especially like this one since it doesn't affect the quality of the light transmission, it has coatings that stop smudges and dust collection, and it's a great value. I'm getting these for a number of my lenses now.

Everyone should use a clear glass protector for their lenses to ptotect their investment. This works pretty well for wide angle lenses, but there are clarity aberrations when zoomed in with a longer lens. That being said, this has been my experience with every lens protector I've ever bought.

Hoya filters are high quality and reasonably priced Japanese camera filters. Yes, it is possible to buy higher end filters, but the price point and quality of Hoya filters agree with the price point of Sigma lenses and high end Chinese lenses. While some people prefer to mount UV filters in front their lenses, I prefer to use lens protectors such as these as they pass more light than a UV filter typically does. Further, sensors in digital cameras are less sensitive to UV than photographic film is. As I grew up in the desert and enjoy landscape photography, the anti-static property of these lens protectors is important to me. They also resist oil deposits from fingerprints, but those are much more easily avoided than dust is. Even you don't live in a desert, old houses tend to be pretty dusty.

I was told that a UV filter might degrade the image quality on my Olympus lenses. So, I purchased this clear glass lens protector and I'm very pleased with it. It is quite thin. It protects the front element of a very expensive lens and the images seem very crisp and sharp.

A mi juicio un producto indispensable si eres fotógrafo aventurero y quieres mantener tus objetivos libres de sustos... Recibido rápido y correcatamebte embalado

A good filter that does not attract dust nor easily stained. So very practical in the field, though may cause minimal additional glare under strong light at certain angle.
