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 

Nikon 52mm Screw-on NC Filter









 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

Purchased for new Nikon lens as a protection for lens glass. Not the cheapest option available but then you can't skimp on these things. Have purchased Hoya in the past and they have always been very good quality.

Screws onto Nikon lens tight. The polarized glass has independent rotation, and doesn't unscrew the base ring. I actually ended up buying two of these, 58 mm and 67 mm, for two of my lenses. Great value for the money, and covers all my amateur photography needs.

The arm on the glass mount is very sturdy and ratcheted so it will not bounce around like others I have used. Be careful to note that glass mount suction is really for one time permanent mount and is not made to be moved to other locations once installed. The other mounts like the air vent is movable.

Nikon D300s fell out of the car, landing on the rim of a $1,400 lens. I couldn't even open the lens cap, it got jammed so hard. Heard rattling glass sound inside, thought the lens was toast. Once I opened it, I was amazed to find the lens glass elements undamaged, this filter sacrificed itself to save the lens. So I'm going with the same one as a replacement and will never again question the value of protective filter.

Love this product... suction is Super!! And you can mount it on your dash or front glass!!

Great for shower use and the glass mount suction cup works well. I also like it for conference calls so I can be on my computer hands free. I was anticipating using it outdoors on the water, but have not done it yet. Good value; easy to setup, and durable.

I bought this to protect an old Nikon 80-200 lens that I have because the glass is flawless and I want to keep it that way. I don't notice any change in the pictures with this filter on vs. off which is what I wanted. I would recommend this product.
