The built quality is amazing. I used it with several lenses using a step-down ring and it worked flawlessly with no issues whatsoever. I haven't noticed any weird colors in my pictures.

Works with Type G (without opening ring) and Type D (with opening ring). Well built and no movement. Highly recommended from an adapter with no AF communication and electronic iris control.

This is a well built UV filter. I did this to attach a non-weatherproof lens with an internal zoom mechanism. A UV filter on the front provides extra protection from the rain for an upcoming trip. The anodizing on the metal ring appears to be of good quality. This and the knurling on the outer ring offer a very good grip when installing and removing. The threading corresponds to the thread on the lens cavity. The filter glass is crystal clear. I found no noticeable degradation between shots taken with and without the filter attached. For the same shot and lighting, my camera didn't adjust the exposure values ​​between turning the UV filter on or off. This is a good UV filter for those of us

Well built and precise ring. Good functioning

I needed a light to go with my webcam and chose this as I liked the flexibility of having a tripod as well as a separate clamp to fix on top of the monitor. The lamp has natural and other light types which allows you to choose whatever works best with your skin colour. You can also dim the loght as required with the built in on/ff and dimmer switch built into the lead.

Super easy to install and use.

I bought this Ruyilam Ring Light as it was recommended to me along with a webcam.
It's very easy to use, and works right out of the box - no issues with USB2 or 3 ports at all.
There is plenty of cable, with a control panel in the centre, housing very intuitive user-friendly buttons.
There are three modes or 'colours' - a default brilliant light, a warm light and a normal enough light. Each mode can be adjusted up to ten times I think, so you can have it really low or really bright or somewhere in between.
I teach a lot online so it is a brilliant addition to any situation involving a webcam and online conferencing or whatever.
In the first photo above the light is clipped on to my laptop which is a fairly normal scenario. Next, there is a photo of how it clips on to the screen. The clip is not quite wide enough for a desktop computer screen and may spring off due to strain if it fits at all. I suppose it is designed more for laptops, although it does come with a very convenient tripod, so it doesn't always have to be fitted onto a screen.
In the other photos above, from left to right, there is a picture with no light, warm light, normal light and lastly the brilliant light. I'm sure it would be easy to get a little bit creative with positioning too.
I would highly recommend this device as it is reasonably priced and it is actually very helpful in providing a lighting solution that you may not have even realised was an issue. Very nice indeed.

Got this Webcam light to remove the shadows from my face when working on Zoom or Teams. I have to say that it does a remarkable job of it.
There are 3 setting to control the colour mode and a great range of brightness to ensure the right amount of light for any task. It comes with a tripod for free standing and a nifty clip to hold the light on the laptop screen just above the camera without masking it.
Unfortunately as good as the light is, it cannot be mounted on a free standing monitor as the clip has not the depth to accommodate this and I think it could be a deal breaker.
Please note manufacturer, you need a monitor mount too.
I like this light as I now look like a Pro, just need some make up to hide the wrinkles.

This is a great Webcam! It has stereo microphones and is High Def.
