I-R interview w/Sigma's Kazuto Yamaki

Imaging-Resource's interview touches on Sigma's lack of m4/3 lenses and Foveon sensor in sizes other than APS-C.

Sigma Q&A with Kazuto Yamaki: Why no Micro Four Thirds lenses, and is a full-frame Foveon feasible?

Manufacturers can't just make a lens and hope it sells.

Sigma's lenses don't offer anything to a 4/3 user. 19/2.8??? Not when there are great 14/2.5, 15/1.7, 17/1.8, and 20/1.7 options. 30/2.8? Not when there is the 42.5/1.4, 45/1.8, and 25/1.4. 60/2.8? Not when there is already a 60/2.8, as well 75/1.8. Also, all of these lenses are bigger than necessary because they cover APS-C.

Sigma's 4/3 products don't sell well because they didn't make a single interesting 4/3 lens.
