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!

This is just incredible. I'm using it with my Sony A7iii and the 24mm f1.4 G Master lens. Will update later with some waterfall shots. Definitely recommend this!

Great sturdy tripod but also reasonably light considering the size. Supports my A7III with the sony 200-600 on a gimbal head without a problem. Can’t see how spending more than this would get you a better tripod/result.
Highly recommended

have a Sony A7iii and I was looking for a good adapter for my 2 Canon lenses, 85mm f/1.2 and 11-24mm wide angle lens. This K&F Concept Adapter fits my Sony A7iii well and supports the lenses. I was skeptical about the sharpness of the photos. However, this adapter really nails the sharpness. It's better not to use the widest aperture, because lenses from other manufacturers work extremely poorly. Both sample photos were taken with this adapter. The shot in Florida was taken with the wide-angle lens. The mountains are recorded with 85mm. Autofocus is excellent on a 7iii body, so I didn't see any significant difference between using the adapter and the native lens. Eyefocus works very well even in low light conditions. The good thing is that I was expecting a lot of vignette, but I was surprised to find out that this lens doesn't produce a large amount of vignette. So the bottom line is that you should give this adapter a try. It fits well, not too tight like some cheap adapters. The build quality is really good. Happy clicking!

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!
