I haven't actually attached this Neutral Density filter to my smartphone yet because I haven't received the adapter that I ordered to attach it to my anamorphic lens, but I've dealt with so many accessories that I don't need to.Simply put, this accessory will do what it says. The rotating ring has very smooth action and has the feel of a very solid build. Being an adjustable neutral density filter, this accessory allows you to fine-tune the amount of light that reaches your camera's sensor so you can shoot with a fully-open aperture without fear of blowing out your image or video. This is a 52mm nd filter, so if you're shooting with a DSLR with a 52mm attachment threads, this will work for you if you're not going the smartphone route like me. If you are using a smartphone you'll an adapter.All-in-all, great piece of tech for the money.

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

Adapter fits perfectly on my Sony a6000. Looks and feels very well made. For a low investMent it allows you to use your legacy Minolta Rokkor lens. You can expand your lens collection inexplicably with those legacy SLR lens. I currently have a Minolta Rokkor MC 50mm and a Vivitar 85-205mm zoom; both fit perfectly to the adapter and the adapter to camera base. You just have go back to your roots and manually adjust all settings. Focusing was easy. I did notice a lag in the viewfinder when adjusting the f stop using the Vivitar zoom, but not difficult to get true view before shooting pics. Rokkor 50mm works great.Just took a couple early morning pics with my Minolta 50mm. 1/320, ISO 3200, and f 1.7 (manual settings) Pic as shot and I didn’t do any editing/corrections. Enjoy!

I purchased this adapter along with the EOS M camera kit to use with my EF and EF-S lenses. After less than a week, I have been able to try out with the EF 50mm F1.4, EF 70-300mm L, EF-S 17-85mm, and EF-S 60mm lenses. The adapter fits perfectly. Same form and fit as the Canon extenders I have. The EOS M is of course made very tiny with any large EF lens. It creates a sort of 'pocket Rebel'. Of course, once you mate with the larger lens, this is no longer going to fit in anything less than a massive coat pocket. The combination of camera, adapter, and lens seems comfortable after brief handling. The EF 50mm was a very comfortable combination, the adapter does not add a very large amount to the overall combination. The upside to this adapter is if you already have a variety of EF and/or EF-S lenses. The image quality of the JPEGs, right out of the camera ranged from expected to stunning (the latter results obtainable with off camera studio flash strobe and soft box). The adapter was immediately a huge part of the EOS M camera purchase. I highly recommend it if you have other lenses. Again, the results I got with the EF-S 60mm macro (and studio lighting) were stunning. It transformed the camera from curiosity to studio prime. No problem using manual mode and Pocket Wizard. Include this adapter in your purchase and you won't be looking back.

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.

For my Nikon 50mm. this is best polarized filter i got

Polarizing filters have many uses whether you want deeper blue skies, cut through reflections in water or suppress glare off your lake pictures or even metallic surfaces.I use polarizers in the above scenarios (although there are certainly others), and started off with a cheap set of Agfa filters just to play around with them. These worked fine for experimenting but did soften the images somewhat compared to the native (non-filtered) glass. This was especially noticeable when doing 100% crops using my Canon L Glass.If you do a quick search for filters, two names come up time and time again, B&W and Hoya as consistently making the best filters and there is a reason for that. They are the best.This is Amazons entry into the market of polarizing filters, arguably the most used filter type.I only have the one lens that uses the 58mm filter thread, the Canon 50mm f1.4 USM. Although not L glass, Canons 50mm prime lenses are renowned for being excellent value and have very good sharpness for the price.The Amazon Basics 58mm polarizing filter comes in a nice frustration free package inside of which you will find the box that contains the filter. The carrying case is very much like those used by B&W. Unfortunately that is where the similarities end.Amazon's filter is quite large in width compared to other circular polarizers and looks like it is made of steel rather than brass. It is still fairly easy to screw on and off my lens however.Unlike a B&W filter which will give you roughly 1.5-2 stops allowing you to shoot at higher speeds, the amazon filter only gives you roughly 0.5 to 1 stop. This was a quick test using a Canon 5d Mk3, the 50mm f1.4 and shooting carp and turtles at a botanical gardens just around the corner from where I live. It is by no means scientific. Just comparing the differences between an Agfa, a B&W and the Amazon circular polarizers under the same conditions.Taking the pictures into Adobe lightroom and comparing them at 100% crops you will see a difference between the different polarizers. The Agfa and Amazon polarizers are nearly the same with Amazons coming in slightly sharper than the Agfa but not as good as a B&W filter. So the Amazon does lower the native resolution of your lens slightly but it is only noticeable when you zoom in. If you are just going to be taking pictures to put on the internet, Facebook or what have you without doing much cropping then the results are certainly usable.This is not something I would put on my L glass but for standard lenses and primes it actually isn't all that bad at all.

I use a Nikon D3100, I bought a Nikon 50mm f/1.8D AF Nikkor Lens. That lens has 58mm threads. I bought the 58mm Tiffen Circular Polarizer filter to use on that lens. At the time of my order it was sold and fulfilled by Amazon. I paid for shipping and received the filter in less than four days. The filter came in a hard plastic box that I use for storing the filter. It looked new and works fine. No filter problems and I give it 5 stars. The only issue is screwing it onto the lens is a bit tricky because you only have half the width to work with but I blame that on my fingers and lack of any real nails. I have noticed that if the filter doesn't go on straight it may make a glare effect but when I see that, I rescrew it on and that takes care of the issue.
