Sigma has scheduled a “New Products Presentation” on their YouTube channel for August 8th at 21:00 Japan Standard time – which is 1pm UK time, 8am Eastern and 5am Pacific on the same date. Sigma hasn’t said what they’re expected to announce or how long it’ll take but it’s expected to be two new 20mm f/1.4 DG DN and 24mm f/1.4 DG DN Art series lenses. We know by the designations in the leaked specs that they’re full-frame lenses, and according to leaked specs, both will be available for full-frame Sony E mount cameras. The leaked specs don’t specify that there’s an L mount version coming, they do list a separate “E-Mount version” for some specs, suggesting that will also come in L mount flavour.

There don’t appear to be any images of the upcoming lenses out in the wild yet, although pretty complete specs have leaked, courtesy of L-Rumors.

The only price suggestion is 152,900 yen for the 20mm f/1.4 DG DN Art which equates to around $1,160 or £950. Certainly not a budget lens but not ridiculously expensive, either, for such a wide aperture at that focal length, especially on full-frame. It’s interesting that they’re releasing two lenses this wide so close together, though. [via L-Rumors]
