Sigma Unveils Two New Lenses for Sony and L-Mount: 24mm f/2 and 90mm f/2.8

Sigma has just unveiled two new lenses for L-Mount and Sony E-mount cameras: the 24mm f/2 and 90mm f/2.8 DG DN Contemporary lenses.

These two new additions bring the I-Series of lenses to a total of six, sitting alongside the 24mm f/3.5, 35mm f/2, 45mm f/2, and 65mm f/2. Each lens features an aperture ring that, as well as the focusing ring, has received a lot of praise from reviewers (myself included) for giving a refined, tactile shooting experience and accurately replicating the feel of vintage glass.

Other distinctive features of the series are the compact size, metal construction, magnetic lens caps, and metal lens hoods.

The 90mm f/2.8 has 11 elements in 10 groups, autofocus via a stepping motor, 9 rounded diaphragm blades, a minimum focusing distance of 19.7 inches (50 cm), dust and weather sealing, and the L-mount version weighs 10.4 oz (295 g).

The 24mm f/2 offers an alternative to the existing 24mm f/3.5 (which at $549 is $90 cheaper but around two thirds the weight and slightly smaller). It shares many of the features of the 90mm except that it has 10 elements in 8 groups, 7 rounded diaphragm blades, a minimum focusing distance of 9.65 inches (24.5 cm), and weighs 12.9 oz (365 g).

Both lenses will cost $639 and will be available to purchase in the next couple of weeks.

Iā€™d be interested in the 90/2.8. The 45/2.8 is an excellent lens but the 65/2 is a disappointment.

Not really sure what gap these lenses are filling in the e mount offerings already out there...

I agree with John on both counts. The 45 is indeed an excellent lens ā€” it's only downside is shooting wide open at close distance. Back off to at least two feet and the lens delivers stellar images wide open. And the 90/2.8 is such an ideal optic from the perspective if size, operation and ā€” from what I've read ā€” optical performance. The 65 is probably a fine lens, but for me, 65 is a focal length that's too much in the middle.
