Sigma Announces the 100-400mm f/5-6.3, a Compact Telephoto Zoom for Sony and L-Mount Cameras

Sigma has announced the release of an affordable new lens for L-Mount and Sony full-frame cameras: the 100-400mm f/5-6.3 DG DN OS Contemporary.

The 100-400mm telephoto zoom is Sigma’s first lens of this type for full-frame cameras and at just $949 it provides Sony shooters with a very affordable lens featuring a range that’s destined to be a solid alternative to Sony's own $2,500 100-400mm f/4.5-5.6 GM OSS.

The lens includes stabilization and a custom button, and is made up of 22 elements in 16 groups, offering what Sigma claims is excellent image quality in a compact size.

The lens weighs 40 oz (1135 g), has a front filter thread of 67 mm, and includes a splash and dustproof bayonet. There is also an optional tripod collar available.

L-mount camera owners also have the option of two teleconverters: the TC-1411 ($399) offers 1.4 x zoom, turning the 100-400mm lens into 140-560mm f/7-9. The TC-2011 ($429) gives 2 x zoom, creating the equivalent of 200-800mm f/10-12.6.

The 100-40mm f/5-6.3 lens will be available to purchase as of July 10.

This lens seems to offer excellent value given its reach and the inclusion of stabilization. Will you be purchasing? Let us know your thoughts in the comments below.

Sony has a 100-400 mm lens but it costs at around $2500

Ergh. Not sure how I missed that. Thanks. Updated.

Looks like a solid option, looking forward to trying one in store when they become available at Wex UK!


I know people feel as though Sony gets wanked a lot... but damn... unmatched third party lens support.

Let's wait for more reviews - the first ones are looking good for Sigma though. The price seems right - 1000$ for the lens, and +/- 150$ for the collar to mount it on a tripod. I've seen prices around 999€'s in Germany - the list price is higher in Europe (they want 1200€'s).
