Fits the Sony VFA49R1 Filter Adapter with a filter inserted. I wish it had an option to connect some type of lanyard to attach to the extra lanyard hole on the camera, but unfortunately it does not. You can find ones on Amazon without the Sony name printed on it for cheaper, but if you want one with the name this seems to be sturdy and of good quality.

I use this filter on my Nikon N80. Works great. For under $10, this is a great buy.

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

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

I ordered and received this filter and went shooting with my Nikon D750. It has a very sturdy build and I was able to get up to 20 second exposures during the daytime in Hawaii with perfect clarity! I highly recommend this filter and don't listen to the negative reviews, just like the wine community there is a certain level of snobbery in photography Ignore the arrogance and enjoy this outstanding bang for your buck filter!!!

If you are looking for a polarizing filter, this one works well for the kit lens on a Nikon D90.

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.

Good filter but doesnt come with a velocity stack adapter
