The Sigma 35mm f2 DG DN Contemporary is an alright lens. It’s hard for me to get excited about something that’s not incredibly special. But if it’s your first 35mm lens, it’s a heck of an option. It’s fantastic for professional-grade work that doesn’t require rough and tumble. In controlled environments, the Sigma 35mm f2 DG DN Contemporary will really shine. However, the autofocus needs improvements. It could really use weather sealing. And there are a few other good options on the market if you’re using E mount. Overall, the Sigma 35mm f2 DG DN Contemporary is in kind of an awkward place. If it’s bundled as a kit lens with the Sigma FP, then that’s fine. Otherwise, there’s no reason to give it another look.
