After the CP+ show, DPReview’s usual Q&A with the CEO of Sigma was awaited with interest.
Sigma FE-mount lenses
Sigma will make lenses for the Sony FE system, but DSLRs are still the top priority.
The strategy is to complement the existing offering, rather than overlapping it. Maybe a ~50mm f/1.4 (well, such a lens would certainly encroach on the Sony 55mm f/1.8), or “something different”.
From the sound of things, some important initial decisions have not been taken yet, so we must be one or two announcements away from seeing a Sigma FE-mount lens.
