Sigma has announced two new lenses in its DG DN Contemporary range of compact and affordable prime lenses for full frame mirrorless cameras. The Sigma 24mm F2 DG DN and 90mm F2.8 DG DN bring a fast wide-angle and a a compact portrait lens to the line-up, which now totals six lenses.

Sigma’s new DG DN Contemporary line-up is a welcome shift for owners of Sony and Panasonic cameras, where there’s been a general trend toward ever larger, ever more expensive optics. These new lenses should balance much more nicely on Sony’s compact A7-series cameras and on Panasonic’s Lumix S range – not to mention, Sigma’s own and very small Sigma fp and Sigma fp L models.

These lenses feature quiet, high-speed stepping motor autofocus equally suitable for both stills and video, and each comes with a manual aperture ring.

The best news is likely to be the price. Both lenses will sell for $669/£549.99, which is well below the price of premium primes for these cameras, and many photographers will willingly swap the wider aperture of full-on pro lenses for the lighter weight and lower cost of these.

Sigma 90mm F2.8 DG DN | C details

Most portrait primes are big, fast and expensive. The new Sigma 90mm F2.8 DG DN | Contemporary bucks the trend by dropping the maximum aperture to F2.8 – which can still give a shallow depth of field effect for portraits – in exchange for much lighter weight and lower cost. These are the main specifications:

Lens construction: 10 groups, 11 elements (5 SLD and 1 aspherical)
Angle-of-view: 27°
Number of diaphragm blades: 9 (rounded diaphragm)
Minimum aperture: F22
Minimum focusing distance: 50cm
Maximum magnification ratio: 1:5
Filter size: 55mm
Dimensions: 64mm×59.7mm.
Weight: 295g 

Price and availability

The Sigma 24mm F2 DG DN | C and 90mm F2.8 DG DN | C will be available from September 24 2021, at a price of $669/£549.99 each.
