What will Sigma deliver lenses too when Canon and Nikon have filed for Chapter 11 due to the very poor lens sales
their own camera line...
That's just what I was going to speculate. Maybe they've improved their foeven stacked photosite technology and are going to bring out a new camera with it. Maybe that's why they've been creating these significantly higher quality lenses and lens-mount change program in preparation for a new camera of their own.
Camera-wise I think Sigma has a lot more catching up to do than with their lenses. I would say a vastly improved Sigma camera is not on the horizon (it's not just about sensor technology, you know).
