+1 Sigma (and other 3rd party makers) have always been 2nd tier, selling below the OEM pricing though often with lesser quality. A niche they filled for a long time. Lots of old used gear with just a Pentax 50mm f/2 that came with the camera and then a suite of Sigma or Tamron lenses. So there was a clear market differentiation: high price and quality versus lower price and quality, people could choose based on their priorities.
But I think that is changing, Sigma has really been upping their game lately and they have potentially an advantage in that they can spread R&D over several mounts from the basic design. And their new usb dock to program lenses at home? Pure genius for the enthusiast market. What gearhead would not want to tinker with the lens programming? And now they announce they will change the mount if you change camera brands? I'm not sure how many will do that but I can envision a scenario where you buy all Sigma glass and the camera is an add on. We always say bodies come and go, glass is forever. Looks to me like Sigma is listening.
