This filter was purchased for a 12~60mm Panasonic lens mounted on an Olympus OM-D E-M5 MKII. It was difficult to screw on because the first thread was difficult to engage properly despite handling the notches milled on the ring. Thinking it had it fitted, it was unpacked when I took the sun visor off. It is therefore important to check that it is tight and fully screwed. Otherwise nothing to complain about, it protects the lens and filters the light

I now have this amazing filter attached to my Olympus 60mm macro lens. The lens has no lens hood, a bad front cap and obviously no filter. This is now on board, along with a tidy front cap and third-party lens hood. 46mm is a little small and fiddly, but this one has a really good knurled ring that feels good in the hand. The thread is also very smooth and positive. The color balance is imperceptibly different, so it doesn't bother when shooting in well-lit close-ups. I love the improvement on this brilliant lens. ricky

As a photographer with over 40 years of experience I have bought many hundreds of UV filters over the years and these days I usually only think of the B+W and HOYA FUSION ones, but my daughter needed a filter for a kit lens so I took a chance cheaper alternative. This brand arrived well packaged, clean and ready for assembly without fiddling with a lens cloth. The quality is amazing and I wouldn't hesitate to buy one again, even at triple the price! awesome filters for all those lenses you want to protect but don't want to waste the whole world. My honest opinion is yes, the frame is thinner and lighter than HOYA and B+W, but it's perfectly fine and the glass and coatings are every bit as good as the top brands, so these filters are absolutes on every level super buy.

have the Olympus OM-D E-M1 Mark II which is a Micro 4/3 camera. As a result, the lenses are tiny and have less glass to cover, making the price of these filters extremely low. So I bought both this K&F Concept 58mm Black Soft Filter 1/4 and the infamous Black Pro-Mist 1/4 Filter. It's all subjective, but I tend to prefer the look of the Tiffen Black Pro-Mist. The K&F is a bit too blooming and the image loses a lot of contrast. This makes the K&F less versatile. Meanwhile, the Tiffen is more balanced, with less bloom and higher contrast. It's perfectly acceptable for everyday use. Given the low price of this K&F filter, I'm still keeping it. But if I had to pick one, it would undoubtedly be the Tiffen Black Pro Mist Filter.

bought the 77mm version of this filter to protect my Olympus 300mm Pro lens. While doing bird photography in Ecuador, I had problems with this lens. All photos were blurred. I had used the lens 2 weeks earlier and the images were crisp. I had to throw away a whole day's work because every picture was bad. I put the lens away for the rest of the trip thinking the lens was going bad. I got home and started testing the lens. I noticed that with the filter, all the images were blurry. So I removed the filter and all the images came out crisp. So be very careful when using this filter at least on Olympus cameras and lenses. I've since put on a B+W filter and it works flawlessly.

Hello, the adapter should be used with manual lenses from the analog era, logically. On an Olympus E-PL7, I was curious about the usability and above all the achievable image quality. Since of course there is no electronic data exchange between the camera, lens and lens adapter, the camera or the image stabilizer should/can be set first to prevent camera shake Reduce. To do this, press the OK button, bring the image stabilizer to the desired setting. Then simply press the Info button and set the originally used focal length at the bottom right and you're done. The lenses came, to name just two, the Olympus G-Zuiko 1:3.5/28mm and the telephoto lens Olympus E-Zuiko 1: 4.0/200 mm. Of course, these are also used analogously on an Olympus OM-4 Ti. The adapter is well made and makes a solid impression. However, he has a slight lateral play on the bayonet. I guess less than a millimeter. But this doesn't affect the focusing at all, at least not with my lenses. I've experienced other things, and even without an adapter solution. So nothing earth-shattering, especially not at this low price. Of course it will then the camera, with the adapter and, for example, a G-Zuiko 3.5 28mm no case more suitable for jackets, and at almost 630 grams also heavier than, for example, with the Lumix 1:1.7 25mm at almost 490 grams. I like this Lumix, no question about it, but compared to the G-Zuiko 3.5 28mm, it seems to be attached to the camera, I would say "less high quality". If you have problems with manual focusing on an E-PL7, for example, I can recommend the Olympus VF-4 attachable viewfinder. The thing is great, so it can be adjusted well without a sectional image and/or microprism ring, as is the case in many analog cameras. Of course, focus peaking can also be used, but this function must then be assigned a button in the menu, e.g. the Fn button for quick access. The test JPEG photos I uploaded are all unprocessed and show quite good sharpness, colors and contrasts. My conclusion: Recommended and inexpensive adapter solution, but also with a slight tolerance on the bayonet.

Bought to use my old Nikkor 50mm 1.8 Ai-s on an Olympus Pen E-PL7 as a portrait lens. The adapter pleases both visually and haptically and is very well made. Securely attaches to Nikon lens, securely snaps onto Pen's MFT bayonet like an Olympus or Panasonic lens. Nothing wobbles, no play. I have not tested the light tightness of the adapter against stray light under darkened conditions. The adapter is quite massive at 97 g, but this is reflected in a balanced weight distribution, a pleasant feel and also in a shake-free handling of the entire camera. In connection with focus peaking, manual focusing is really fun. I can use it to focus manually at least as well and quickly as I used to with the sectional image screen of the analogue SLR camera.

Got this to reduce overexposure with wide angle Canon 17-40 4L lens. Very happy with the results so far and it's really great for long exposures. I've been a K&F lens filter for a number of years and these have been my primary ND filters.
