I have the 67mm on my Sony a7iii on my 85mm Sony lens. It's so clear you don't even know it's on. The image quality is exactly the same without any problems. It blends into the camera and protects your expensive lens from damage. To assemble it, you turn it in circles several times to tighten it. No instructions are provided, but pretty much self-explanatory. More information on their website. There is also a 1 year warranty period if you register the lens from the date of purchase. These can be replaced at a much cheaper cost than having to buy your expensive lens again!

It worked great on my Sony lens.

K&F Concept Polarizing 67mm Lens Cap. I like these lens caps because they are made of very high quality steel with polarizing glass to not only protect your glass (lenses) but also allow you to change the polarization by rotating to get the best possible photos for the lighting conditions. The lens also has several special coating layers to intensify the colors while reducing glare. I highly recommend the K&F Concept lens caps as I use the K&F on all my RF and older EF lenses.

I recently bought the 67mm polarizing filter for my Sony A6000 in combination with the SEL16-55G lens and am very happy with my choice overall! ✔️ Improved image quality: The polarizing filter reduces unwanted reflections and enhances colors, which delivers impressive results, especially for landscape shots. ✔️ Robust workmanship: The filter feels solid and high-quality, which suggests a long service life. ✔️ Easy to use: Screwing the filter onto the lens is easy and works smoothly. ❌ Difficult to unscrew: Unfortunately, the filter is difficult to unscrew from the lens, which can be a bit frustrating when changing lenses quickly. Overall, the 67mm polarizing filter largely met my expectations.

I have a Sony A7III with some of the Tamron lenses they recently released, 67mm thread on the dUKx. I first used the ND on a daylight midday shoot and was amazed by the results. The best part is that I can choose the number of stops I need to make the zebras disappear with ease. Ease of movement and robust construction. Only negative is that the sun visors don't fit after turning on the ND. Not a deal breaker but be aware.

EDIT: I also took it on a trip to Lake Tahoe and it came in really handy for longer exposures and more sky contrast. Awesome and so easy to use!

I use the 67mm version of this filter. Since there are no external threads to mount a hood (I use this with a stepup ring for other lens sizes), I use a 67mm Amazon product ($9.50 for two) "67mm Camera Lens Hood - Rubber - Set of 2 - Collapsible in 3 Steps - Sun Shade/Shield", Mount the rubber hood BEFORE the VND, fold the rubber back over the lens, then mount the VND, set it where I want it, then pull the rubber hood out over the VND adjustment ring. A little awkward, but it works.
