TTArtisan 7.5mm F2 魚眼広角 APS-C レンズ

This thing is bright & sharp, perfect for landscape and astro. There’s a tiny 10 stop ND filter included that can be installed on the back of the lens. It’s super useful! I don’t think people ever mentioned the quality of the ND filter on YouTube or anywhere but it is GOOD. There’s no color cast and I think they had nano coating on it to prevent oil & dust stains. It’s not as easy as cleaning normal square filters though considering the oleophobic (or hydrophobic) layer repels water so much. The only thing I wish is that they come with 4 or 6 stop ND as well. But hey for the money, this thing worth absolutely every single penny!

I use this lens for my wide angle shots. It's very easy to manual focus this lens. If you buy it you will fall in love with this ultra wide lens!!

I ultimately returned it and bought a used more established lens. This lens feels cheap but image quality was good and I had no beef with its performance. Good value.
