Construction is very good with rubberized edge ridges for easy installation and removal, especially important for a filter that will only be used for night sky photography. Light transmission is good with no apparent chromatic aberration from edge to edge. The filter doesn't easily attract dust and cleans well with a quality microfiber cloth. While I've only taken a few night test shots, the filter appears to be very effective, especially for sodium vapor light pollution. One more item of note - the filter case is the best I've ever received with a filter of any price!

already had rings to use Canon FD lenses on my Mirrorless Samsung NX30 but I wasn't entirely happy with them... on a friend's suggestion I wanted to try them and I have to say that from a constructive point of view they are really well done . No mechanical play, the lens is firmly attached to both the ring and the camera body and not even the stop-down ring of the apertures (which allows you to set the aperture to the desired value) remains locked in the selected position. We recommend!!! Top shipping service (as always)...!

Use this adapter ring to attach my mother's 300mm lens to my Samsung nx. It's well made and feels very stable even after repeated use.

Good resolution. Fast using Samsung S23. Decent range.

I like the selfie ring light, only issue max brightness is not that bright but it is good.Also, the buttons to control the light need to be closer to base rather than hanging in the middle of power cable.

Although there are numerous choices for video lighting; a larger ring diameter still produces a unique effect unmatched by a smaller unit. It does have a electrical quirk: the "off" position of the power button leaves a dim light rather than a truly off state, requiring one to use the socket switch instead.Overall the Neewer unit represents superb value: a comparable name brand product is easily multiple the cost.

When you open the incoming package, you will find that the packaging is very high quality. The brand is very careful in presenting their products and the materials are of high quality. The filter holder and adapter ring are metal and the filter holder has a spongy area whose function is to seal with the filter without letting light through. Once the filter holder is attached, it is easy to move. crtsal 100x100 quality is very good, with highly polished edges. The filter holder has two slots for square filters, but the advantage is that the ring screwed on the lens can be screwed with another round filter, for example a polarizing filter. I think the picture is very good. As with the brand's round filter, the sharpness is not lost, the color cast did not catch my eye, anything that can be edited during development is appreciated. The ND1000 filter included in the kit enables long exposures in strong light. The sample photos are photos taken on a cloudy afternoon with and without a filter. Those with filters were made with an exposure time of 20 seconds.

Exactly what I needed at a fantastic price!
