A couple of things regarding Sigma’s lens roadmap have come to my ears (thanks).
- “No rush to get the 24-70mm out”. The 24-70mm f/2.8 OS Art may be released after Canon’s own stabilized 24-70mm f/2.8 lens. The Sigma will do more harm to the Canon if it comes out after it. Also, the new 24-70mm is expected to hit the already not-so-good sales of the 24-105mm quite a bit, so Sigma is willing to leave a bit of room for this lens for a couple more months.
- “70-200mm f/2.8 OS Art? Forget it”. I’m told that Sigma will rather stick to fast primes in this range — at least in a close future. It means a 85, a 135, and perhaps a 200mm. All less expensive than the Canon and Nikon competitors.
- The rumored APS-C zoom lens is still planned.
- “Maximum 1 more focal length this year to come. No word on how many lenses that will be though…”. This may be hinting at a recent rumor about 12-24mm DG Contemporary and Art siblings. However, there’s no indication of a focal length range, but only a single FL.
- Sigma knows that its lenses work well on the Sony A7 series of mirrorless cameras with the Metabones adapter, and ponders whether it would be a good thing to let people know “officially” about it, and to promote using lenses with a third-party adapter.
This source nailed it with the announcement of the 24mm f/1.4 Art, so they may be onto something here as well. Still, take everything with a pinch of salt!
