I was tempted to rate the lens at four stares as the lens bag was missing and as a still photographer, I would much prefer click stops on the aperture.However, I was aware of the lack of click stops. I am delighted with the fit and finish of the lens and one would not think this is a $140 unit. It is likely to be compared to the Rokinon 8mm/2.8 which is $124 more expensive. The 7artisans 7,5mm/2.8 is at a price that it can be used occasionally. I would like to give credit to the box and graphic designers, for an inexpensive lens, this borders on being a presentation box. Please keep the "Made In China" sticker neatly on a side panel. Gives the lens a touch of class, thank you.When it comes to performance, I would buy this lens again and would recommend it to someone in my camera club with the following information. I did some basic user testing. The lens was mounted on a Sony a6000, shot in raw, on and off a tripod, and downloaded to Lightroom 5.7. I made my judgment calls at the 1 to 1 magnification ratio. From my perspective, f/8 was the sweet spot for the way I will use the lens. In landscape orientation, it is soft on the vertical edges, especially the corners with cromatic aberration. The cromatic aberration can be corrected in LR. I am pleasantly surprised at how sharp the lens is and the fact that it can be focused very close indeed. I was pleased with how little flair was apparent when the sun was peaking through fir tree branches 1/3 of the way into the frame One last thing, while the lens shade can be removed, I have had no lens vignetting with my lens. I did take my lens shade off, even when I know better, and my 81yr. old hands had difficulty getting it fully on in proper orientation. I solved this by using a matchstick with a minute dab of Helimax-xp Optical Helicoid Grease at 1/2 in. intervals to the threads of the lens body. The shade went back on with no problem. Another precision grease should work fine if you have this problem. Be careful. Thanks again.
