During today’s live stream event, Sigma has announced their new Sigma 20mm f/2 DG DN Contemporary series lens for Leica L and Sony E mount. It joins the Sigma 24mm f/2, 24mm f/3.5, 35mm f/2, 45mm f/2.8, 65mm f/2 and 90mm g/2.8 DG DN Contemporary series lens lineup. Sigma says their goal was to create a “palm-sized large-aperture ultra-wide-angle lens” for landscapes, street photography, or whoever else you might want to use a full-frame 20mm lens.
With a length of only 72.4mm and a maximum diameter of 70mm, “palm-sized” definitely seems to be an accurate description, and with a weight of only 370g, it shouldn’t add much of a strain on your back or shoulder when adding it to your bag. In case you missed the lives stream event, you can watch it again here.
What’s particularly appealing about the new Sigma 20mm f/2 DG DN Contemporary is that it actually has a filter thread on the front – something lacking from the Sigma 20mm f/1.4 DG HSM Art series lens. For landscape shooters, in particular, who don’t typically need super wide apertures and can stop down a little for maximum sharpness and more depth of field, this feature alone could sway them if they’re shooting Sony E or Leica L mount bodies.
|Lens mount||Sony E, Leica L|
|Angle of view||94.5°|
|Minimum Focus Distance||22cm|
|Optics||13 elements in 11 groups|
|Aperture blades||9, rounded|
|Filter size||62mm (front)|
|Dimensions||70 x 720.4mm|
The dimensions make it almost identical in both size and weight to the Sigma 24mm f/2 DG DN Contemporary lens, with an all-metal design, magnetic lens cap and manual aperture ring. Sigma says that it’s particularly well suited to astrophotography due to the “well-controlled sagittal comma flare” properties of the elements and their coatings.
