I don't buy any more photo gear. I have plenty and more. However, once in a while there is an exception made

I'm just a human.
This brand new Viltrox 9mm f/2.8 autofocus lens for Z/DX drew my attention and I did a pre-order before the official launch. After a few days it arrived. looking almost identical in outline to its longer sibling Viltrox AF 20/2.8, it shares the extreme low weight and almost ridiculously low price. Set wide open, it might not be the sharpest lens in the cupboard; however stopped down a little it is amazing and bear evidence to what the clever people of third party lens nakers can come up with. It has extremely low colour aberration, so colour rendition is excellent, image contrast is pleasing without being too harsh, and the icing of the cake is the lowest level of corner vignetting I've yet seen in a superwide lens. And the price?? I paid less than USD 200 incl. UPS express shipping.
Since the IR portrait of the lens below shows there are IR reflective areas of the lens casing, it's no wonder the lens showed some (mild) IR hot spots. However, even those might be tolerated on occasion. Almost all lenses for the Z mount, native or adapted, will have this issue to some extent.
