Today, Sigma announced their latest Contemporary Series lens, the Sigma 20mm F2 DG DN I Contemporary lens. This marks the seventh L-mount lens release by Sigma and this time they’re going ultra-wide. Sigma is definitely looking to provide a healthy lineup of compact prime lenses for both photographers and videographers but how does it stack up and what can we expect? Here are my initial thoughts on the news.

Why It Matters

With an ultra-wide field of view and a standard 62mm threaded mount for use with a number of available filters, the Sigma 20mm F2 Contemporary lends itself very well for handheld vlogging and live-streaming applications. Whether day-in-the-life vlogging, streaming a worship service, or an overhead shot for demos, I can see this camera paired on the Sigma fp L or similar “box camera” with great effect. On the photography side, an ultra-wide is a must for any kind of astrophotography, real-estate or landscape photography – the wider and faster the lens, the better!

While Sigma included a couple of street photography examples, I’m not quite sure about opting for the 20mm over something like the 35mm or even the 24mm but it’s definitely doable. The samples provided by Sigma definitely speak to the lens’s abilities and possibilities it affords photographers and videographers alike.

Pricing and Availability

If you’re shooting with either an E-Mount or L-Mount camera system and have been turned off by the high cost of ultra-wide lenses fret not. The Sigma 20mm F2 DG DN I will give you a big picture perspective at a reasonable price point. The lens is expected to be available beginning February 25, 2022, for around $700 MSRP.
