This thing is great! Nice to have some extra protection on the lens! The UV filter isn't really needed on my camera but it's a nice addition to my lens! The build quality is great, everything about this brand is really high quality and this is no exception! A great addition to the camera bag!

Arrived on time!
Fits well on my Samsung S24!
Polarizing filter! I need to buy the lens cap!
The various components are perhaps a little expensive!

Hello everyone, since there are no reviews yet I thought I'd write one. The adapter arrived 4 days ago and was even faster than stated. So that's a plus point. Now to the adapter: It's just an adapter that allows you to attach the lenses to the Samsung (NX Mount). No electronic data is passed on to the camera or the lens! Which is also correct, since nothing else is advertised either. Workmanship: The entire adapter is made of metal and makes a stable impression. The EF / EF-S lenses are very tight and don't wobble. The mount for the Samsung bayonet has a very small scope that can be safely ignored. Detaching the lenses works without the lens getting stuck anywhere. Application: Since no electronic data is exchanged, focusing is done manually. The focus help on the Samsung camera is activated with the OK button (Samsung NX300M), a small image section is enlarged and the "sharp edges" are displayed using the focus peak. The aperture is either always the open aperture or you set it beforehand on the Canon camera (choose aperture, press aperture preview button, remove lens) A somewhat cumbersome way. It's definitely more fun with completely manual lenses like those from Samyang or Walimex. But if you are comfortable with working with an aperture, you can have a lot of fun. Tested lenses: EF-S 18-55mm IS II <- OK EF-S 55-250mm IS II <- OK EF 50mm f/1.8 II <- OK EF-S 10-18mm STM <- Doesn't work because manual focus only works with an electrical voltage Conclusion: The adapter does what it promises. You can't expect much for 17 euros. I will definitely use it more often. If you can overlook the hurdles (aperture, focus), this adapter is definitely recommended. If you just want to take photos, you should stick to the original Samsung lenses. Attachment: Product photo and an example picture I made in the garden on the fly.

originally bought another adapter to attach a cannon lens to my Samsung camera but it didn't fit. So I tried this one and it fits perfectly and snaps in place easily. It's not electronically powered, so you'll have to shoot manually, which isn't a problem once you're used to it. This is great for being able to expand the lenses for Samsung cameras as they are limited in choices and sometimes a lot more expensive than looking for a used gun lens. I have not used this item extensively as the gun lens I bought is an old 300mm lens and I currently prefer a different lens. Hopefully in the future I can find a gun lens I like and be able to use this adapter again.

UV filters are often used to block extended UV rays on the front of a lens and as a longtime photographer I remember the days when a UV filter was a must to protect your lenses over the long term. ...or at least that was the theory.

Unfortunately, much of this belief persists to this day, and while the benefits of a UV filter that provides protection is still a hotly debated topic, UV filters offer a very good benefit...they keep dirt/grime/fingerprints back from the front Main element of a camera lens.

In wedding photography, it's not uncommon for a child/baby/drunk adult to reach out and try to touch your lens...in fact, attempts to do so can produce some of the most incredible shots if the timing is right.

However, the expense and difficulty of cleaning a good, high-end lens is often many times more difficult than simply cleaning a lens cover on the front...which is where UV filters usually come in...they do the job good job direct contact with the actual lens.

I've used many different types of filters over my decades of photography, and among these, UV filters are probably the ones that offer the widest range of quality.

This is the first K&F filter I've used and I've been using it on a Sigma ART lens for a week.

I'm happy to say that this filter is a nice mid to high end UV protector. Unlike so many cheaper UV filters, this one doesn't seem to introduce any easily noticeable color shift or image distortion with the image.

While I'm sure if I start pixeling and comparing this UV filter to a $200+ filter I could probably find a few glitches here and there. In fact, this filter is half the price of many of the other upper mid-range filters.

... and let's be honest. The primary goal of a UV filter is protection. A decent UV filter shouldn't noticeably alter your images. In this respect, this product does exactly what it is supposed to.

One thing the K&F excels at, however, is the case in which the filter is packaged.

The case is a hard cylindrical case that is easy to twist open. However, the nicer aspect of this filter is the fact that the housing has a silicone ring with grooves in it that holds the filter in place while it is in the housing. This is something many other manufacturers do NOT (including a large number of more high-end filter manufacturers).

While yes, this is the first real experience with a K&F filter, for me...after looking at the attention to detail they have done, I am now in the market for a few others of theirs :)

With modern DSLR cameras, there is a lot of debate as to whether UV filters are of any use. I'm in the camp that says there are definite benefits. First, there are arguments that the UV filter can protect the sensor in your camera from long-term UV degradation. Second, a good quality filter provides a layer of protection for the front of your camera lens. I was shooting in a very windy location and a door caught the wind and banged the front of my lens before I could get a hold of it. I was lucky that the hit wasn't worse, but the lens got a small chip on the front plastic. This filter is metal, screws directly on, and will protect the front of the lens from such damage in the future. The lens could still be damaged in other ways, but it's a layer of protection from those unexpected bumps. In the future, if the lens gets bumped and the filter destroyed, I'll be grateful that the filter took the hit instead of the lens. The filter is much cheaper to replace!

This helped with UV protection during the day and also helped prevent scratches on my camera lens. It's very thin and you hardly notice it's on. I can also put my lens cover on it so it doesn't get damaged. Worth the investment

While a clear filter might not be the most exciting piece of camera gear, it can prove valuable when it comes to protecting your expensive lens investment. This filter is optically clear and does not add a color cast. From my readings I hardly see any loss of light, nor have I encountered any internal reflections. The filter has some recessed grips on the outside that make installation and removal easier. Many of my older filters got stuck and were difficult to remove, but I don't expect that with this one. It's not overly thin, but I didn't detect any vignetting with it on the wide end of my 24-70 Lumix S Pro lens.

If you tend to shoot in harsh environments or places where there may be contact with your front lens element, this is something you should seriously consider. It's affordable protection that's well worth it.
