Nikon 35mm f1.8

This little lens has been my workhorse from the day I got it. It immediately replaced the kit lens and has taken, by far, the most pictures of all my lenses to date. It’s very cheap (relative to most other lenses) but still easily one of my sharpest lenses. Things to keep in mind is that it’s a DX lens, which means it will vignette quite strongly on a full frame body, and also that it has a bit more distortion than you would typically expect from a lens like this. It’s easily corrected in post though, so no big deal. Bottom line: if you have a DX camera, this lens should already be on it.
