Buying a decent quality filter to protect a good lens can be an exercise in how much one feels like reading often-conflicting reviews and opinions. It's sometimes as bad as reading reviews with comments as to why one DSLR may be better than another, or why one zoom lens may produce 0.2% more barrel distortion than another. But this 

Marumi 52mm DHG MC Lens Protect Slim Filter









 seems to be one of the less pretentious filters in a competitive market.Years ago it was the UV vs. skylight filter argument, and then multicoated filters arrived on the market, and that seemed to change everything. Photographers bought these arguments in many cases, and were often caught up in the maelstrom of getting rid of perfectly good filters for the sake of having the latest and greatest piece of glass on the front of their lens.But along the way something was forgotten, an even older point that was forgotten over the years: drop your lens and the chances are slim that the front glass element will get damaged. It's the filter threads on the front of the lens that usually gets the impact, and as any camera repairman can tell you, this can get costly to the point of being prohibitive in some cases. One good way to protect against this is to use your lens shade; the other is to use a UV, skylight or protective filter. Just because a lens may be reasonably priced is no reason to put a cheap and possibly inferior filter on it. I fortunately have a small supply of the older Nikon 52mm L37C UV haze filters that have been in use for years, but the

 is its multi-coated replacement, and does not affect color balance. It's a protective filter that also reduces glare for outdoor shooting. If you explore here, you'll find others, such as some from Hoya, Sigma and others. It's a subjective choice, but be sure to get a good one.The 

Marumi 52mm DHG MC Lens Protect Slim Filter









 was made in Japan, and came packaged in a rectangular clamshell package with nothing touching the filter surface. Some filters come in soft plastic pouches where the plastic rubs against the surface, which isn't good. It's well made, with no play between the glass and the metal ring. The six-layer low reflective multicoating on this DHG (Digital High Grade) filter keeps reflections from bouncing between the back side of the filter and the front element of the lens. The black non-reflective satin metal frame helps to eliminate reflections, and Marumi notes that a black ink process has been used on the glass edge to eliminate flare. The frame has some slight ribbing on the edge of the metal frame to make it easier for removal when necessary. This is considered to be a low-profile filter, and exhibited no edge vignetting even when stacked with a polarizer.Giving credit where credit is due, I had read various blurbs about the Marumi Super DHG Filters, but a friend who is a sports photographer had personally recommended them highly, noting that they were excellent for guarding against oily smudges and water spots, something that he encounters regularly. Using my 

Nikon MicroKlear Cleaning Cloth









, I found the same, and my review of that cleaning cloth explains a bit more about cleaning techniques used from experience.Bottom line: this is an excellent filter for basic lens protection, and it's more reasonably priced than might be expected. This was purchased to protect a new Nikkor lens that I own, and even though I already have an array of Nikon and Hoya 52mm filters, this seemed to closely resemble the Nikon NC Filter in terms of being color neutral. You may have to search here for your size, but this is a highly recommended 5-star product, and I'm glad that I listened to the advice of my friend.6/4/2012

It's a UV filter. Screws on. Stays on. Protects the lens from smashes and such.

I got these to use with my Helios 44M-4 vintage lens, which has a 52mm filter thread. They have a slightly blue color tint which is so barely noticeable that I had to use do comparisons with an RGB parade in Adobe Premiere to see it (I got these for video), although it seems to be worse with the darker filters. It's hard to complain about at this price, and it's the sort of thing that can easily be mitigated with manual white balance. I also haven't noticed any artifacts in the bokeh, like the squiggly lines you sometimes get with cheap plastic filters. Overall, I would say this is a good low-budget solution.

Faultless!The Neutral Density (ND) filters are wonderful and they do stop the light hitting the sensors no problem.The other filters are perfect too but normally you don't need a UV filter on a digital camera but I use it just to protect the lens.The other filters will them screw onto the UV filter but don't screw too tight.The polarised filter does have a revolving rim "GASP" and is ideal. I didn't realise it had a revolving rim until I actually used it and screwed it on.I can tell you now that anyone giving these filters and less than 5 stars are bonkers because these are superb.The wallets they came in are and look really well made as does the filters. The rubber lens shade is really good too and will push flat to allow it to fit in your case. I have no use for the plastic screw on shade so that will be used for something when I have my thinking head on.The lens cap is a good one and comes with a lanyard but I will not use the lanyard as I do not want it dangling from the camera.I would recommend these to anyone who want cheap but quality lenses.

I do not use these for the UV filter but as a good quality, low cost lens protector. That said:My 1st Tiffen was a 55mm UV Protector I got for the kit lens that came with a Sony a7ii; an FE 28-70. I was so happy with the purchase that I have since purchased three additional Tiffen UV Protection Filters. One is on a Sony E 55-210 I bought used and one is on a Samyang 35mm I bought new. The one I am writing this review for I assume is still on the Sony FE 50mm I bought new but returned and forgot to remove the filter.The point? I treat my lenses, new or used, like I treat a cell phone. That being the phone stays in the box until I have a protective case for them and lenses stay in the box until I have a protective filter to pair them with. And the one I forgot to remove from the returned lens? That is how confident in the Tiffen filters I am. Once I put one on a lens, I never need to think about it again.I have used several brands in several sizes ranging from the cheaper Altura and Polaroid to the mid range Hoya and B & W.Where does Tiffen fit? Well they are no Hoya or B & W but I am no professional photographer. I am an amateur who mostly enjoys street photography when I travel and for my money Tiffen is the best. Yes, you can spend more and get better glass and if you really have reason to worry about ghosting you should look for a higher end lens. That isn't me saying ghosting has been a problem for me. I normally use a lens hood and I think that helps cut down on light reflection. I have noticed some minor issues with it on some shots I have taken in direct bright light conditions but not enough to justify the higher price.I do not stack filters as I haven't had a need to so I can not give an opinion on that topic. I would assume that the risk of ghosting would increase.The short version is this. The Tiffen UV Protection Filter is well made with good quality glass and a metal ring with threading I do not worry will cross thread or strip. They do what I need by protecting my lens. If I was buying a ND or polarizers I might buy a more costly brand but for everyday protection, Tiffen is all I need and the best for my money.Tiffen say it best in their own product description; A small price to pay to protect your investment.

I have these for each of my lenses. I just leave the UV filter on all the time to protect the lens. They are nice and clear and just as good as name brand for the price.

Good to have this as it doubles up as dust protection for lens apart from being a UV filter

I first purchased the K&F Nano Series filter for one of my lenses. I believe it was for my Nikon 80-200mm F2.8 D ED lens. That lens produces really sharp images at distance and is not a close focus lens, even noted by Nikon. I bought the lens used and it came with a beat up UV filter. I was getting ghosting and when I removed the filter the ghosting was significantly reduced. I ended up buying several more for my other lenses. I also use B+W filters too. Well made filters as well, but a little more costly. The K&F is by no means a $100 filter, but for the price it does what I need. I especially like the nano-coating that resists grease and water. Worked well when I was photographing at the beach. Easy to clean the sea mist off without smearing. We really do not need UV filters anymore with digital since UV does not interfere with the sensor like it did with film. I simply use them to keep from having to clean the front elements of my lenses all the time. I feel reducing that to a minimum will prevent potentially scratching the element. I know there are a few schools of thought on this topic, but I just do what I am comfortable with. From what I read and can tell the filter is glass and not plastic, which is nice these days. I have them on all my lenses now and happy with them.
