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

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.

I used an Apexel 12-24X macro lens for a few months but the 24 was unusable and the 12 required you to be so close that only a small portion was in focus. This lens lets you get very close, but still include enough in the picture to identify more than just surrounding textures. Ease of use is outstanding. Love the short video they have you watch before use. I have't tried the wide angle as I have the new iPhone wide angle version, I just wanted the macro. It includes a lanyard and a clip on light which are nice additions. I paid almost 3 times as much for this lens, but am so happy I bought it because the pictures are worth it (especially flowers!).

I am enjoying my new lenses so much! I was looking for clear, close macro photos and this lens works great.

I posted 5 photos:1. regular iPhone 8 Plus - no lens2. wide angle lens3. macro - when far from objects4. macro - when close to object5. what it looks likeThe lens screws right onto the clip. Pretty simple.I saw some previous reviews where people had a hard time focusing the macro. This is a non-issue if you get close to the object. Gives a nice tight focus.The quality seems pretty good. I have yet to take it out and use it in the wild, hah. So I may need to update my review later.The one thing I don’t love is the clip because I’m not sure how well it will hold if I put my phone on a gimbal or move around too much. I DID however realize there is a protective plastic layer your can rip off. It comes with the packaging, but is transparent so not super visible. Make sure to take it off! The grip is much better without it.It comes in a nice box! Plus a pretty bright light, I’m assuming for selfies... and a lanyard.For this price, I think it is worth it! Although, I’m curious to try the Moment lens/case. It seems a little pricey... I would rather invest that money in a lens for my mirrorless.

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

Great lens. With macro lens, image is gets unbelievably close up and is crystal clear.

I am a lash artist and the macro lens is perfect for up close to the definition in the lashes
