I bought this lens like a couple of weeks back and have used it for Astro Photography and I am pretty much satisfied with this lens performance, It took really amazing pics. I am not sure how to focus to infinity would be been much better if they have that feature on the lens

I have never owned an ultra-wide-angle lens before. This one intrigued me, especially because of the price. However, I own a D7100, and this lens isn't fully compatible with my camera. I read the comments on the Nikon USA forum, and decided to purchase the lens anyway.

Just got this lens today and mounted it on my D5200 and it worked perfectly. It is about the size and weight of a 18-55 kit lens. It delivers the wide angles and focuses very quickly without a sound. I took some pictures indoors and outside and am very happy with the image quality.

Consistent Output; Lightweight; Quick Focus; Sharp Focus
