Sigma will soon announce three new lenses: two lenses (Sigma 17mm F4 DG DN C and Sigma 50mm F2 DG DN C) for Full Frame and one (Sigma 23mm F1.4 DC DN C) for Aps-C.
Below are the key specfications:
Sigma 17mm F4 DG DN | Contemporary (Full Frame)
- Lens construction: 9 elements in 8 groups
- Shortest shooting distance: 12cm
- Maximum magnification: 1:3.6
- Filter diameter: 55mm
- Size: φ64.0mm x 48.8mm (50.8mm for E mount version)
- Weight: 225g (220g for E-mount version)
- Magnetic metal cap
Sigma 50mm F2 DG DN | Contemporary (Full Frame)
- Lens construction: 11 elements in 9 groups
- Shortest shooting distance: 45cm
- Maximum magnification: 1:6.9
- Filter diameter: 58mm
- Size: φ70.0 x 68.0mm (70.0mm for E mount version)
- Weight: 350g (345g for E-mount version)
- Compatible with magnetic metal caps
Sigma 23mm F1.4 DC DN | Contemporary (APS-C)
- Lens construction: 13 elements in 10 groups
- Shortest shooting distance: 25cm
- Maximum magnification: 1:7.3
- Filter diameter: 52mm
- Size: φ65.8 x 76.9mm
- Weight: 340g

It is unknown whether there will be some kind of announcement by CP+ or whether they will appear after CP+. The size and weight of Sigma 17mm F4 DG DN C are exactly the same as the current Sigma 24mm F3.5 DG DN, so it is surprisingly small and lightweight for an ultra-wide angle.
Sigma 23mm F1.4 DC DN seems to be the first F1.4 lens for APS-C in a long time. Unfortunately, unlike before, it seems that it is not for Micro Four Thirds. 23mm is a focal length that seems easy to use even with a 4/3 sensor, so it’s a shame. The size is about the same as “30mm F1.4 DC DN“, but the weight is slightly heavier. Compared to the “XF23mmF1.4 R LM WR“, the shortest shooting distance and shooting magnification seem to be a lens that is a little harder to get close to.
