Sigma really did turn things around and they should get credit for that.
They went from having a poor reputation for quality control and optics
in the 1980's - mid 1990's, to being considered solid in both areas to
being an innovator and leader in lens offerings.
There are a lot of their current lenses - especially macros - that I
wish were available in K mount. But a lot of lenses from the mid 1990's
and earlier have poor reputations.

I don't know real old sigma. When I got back into photography they
had some "decent optical quality for the price" lenses. These days
they seem to be doing some very top end work. Their 18-35/1.8 is
groundbreaking, and supposedly very, very sharp. Their art series
lenses have stellar reputations. My two biggest complaints about a
lot of their new lenses is that they aren't available in Pentax mount,
and I couldn't afford them if they were.
