It says that it is Made In Japan. We all know the Japanese make great things that last a long time. I don't know what else to say. Its great for what it is made to do. I actually found this product from a tech YouTuber who gave advice aimed toward budget buyers who might want to get in to YouTube. I use this lens on a Vixia R800. I give it 4 stars b/c of the confusion that Amazon caused me when choosing vendors.A negative I have about this item is not about the item itself but the third party vendor (there is an adapter that comes w/ the lens it was taped to the outside of the box; I'm sure that wasn't supposed to be like that) I wish it had come directly from Amazon. I learned. I now will only buy items from Amazon directly unless it is from a well known vendor.I like this lens. I use it on several cameras to tighten up the view during live performances. Very happy with the results. The picture quality is very good and you don't notice any distortion (bending) of the image that some lenses cause. Would recommend to others,While I liked this for price and overall sharpness - the lens has a real problem with flare and glare when using with most lightening situations. I tried it with a lens hood but still got flare and the hood caused vignetting. Vignetting not lens' fault but could not solve flare issue. This implies needing better coating.Macro works well. Images are sharp enough and lens is sturdy and well made except for glare issue.Would give a higher score if I knew how to circumvent the erroneous lens flare. Considering all ideas famI bought this for a Canon Vixia hf r800. The adapter ring does hit the camera before it is fully tighten down. I sanded the camera strap loop slightly to gain the needed clearance. The HF R800 does have a setting that will widen your shot a little but I wanted more.The lens seems fine, but the adapter ring does not fit onto a Canon Vixia HF R800, as it will not screw in. It was advertised that this lens would fit on this model camera, but it does not.I see no problems with it yet, the mike works fine with the lens on camera.Perfect fit, easy to install, but not the highest of quality, it does produce alot of sun flares and glare.
