*For the cost* (very important) this lens does everything you need a cheap, fast 35 f/2 to do. The build quality and feel are surprisingly good. The focus ring is satisfyingly tactile — smooth and large enough for my fingers to have an easy, snug grip, unlike my Nikkor D lenses. It's not the widest aperture for a 35, but for less than $100 you get functionality and value. We use this lens to film vlogs indoors with cheap studio lighting and it works well enough for our needs. It's soft all the way to the edges at F2 and difficult to focus with. The AF is quite slow but seems accurate enough. I plan to try this lens for astrophotography but don't have high hopes due to the lack of sharpness at F2, but I'll keep an open mind until I test it. However, when attenuated to f/2.8, clarity and sharpness improve significantly. We shoot our indoor vlogs at f3.2 for that extra depth of field, but would have no problem dropping down to 2.8 if needed, and the improved sharpness is nice at 3.2. I've attached two files — a full-size image of a section of tree, unprocessed at f/2 (1/4000th of a second to eliminate motion blur) and a cropped version of that file to show the poor sharpness right in the center of the frame. The lens is a nice size. Slightly larger than my Nikkor 50mm but smaller than my Rokinon 85mm. It works well with my Nikon D500 and when the focus is where you need it the images look good. It also focuses close enough for close-up macro photography, so that's nice. That sucks compared to other more expensive 35s out there, but these lenses cost hundreds and hundreds of dollars more. So I give it a 4/5. It's a great lens for getting the feel of a 35mm lens, but I wouldn't recommend it at all for professional use. + Good workmanship Inexpensive close-up focus - Slow autofocus, not sharp at f/2
