I tried to find a list of all sigma lenses and date of release (just like Wikipedia has for canon) but couldn’t find anything. Before or maybe just when the internet started so not many articles.
“It was around 10 years right? EOS 650 introduced in 1987, and in 1998 Sigma has 28-70mm F2.8 EX ASPHERICAL. There's little info if there's other 3rd party”
It's from Sigma's official website. For Tamron/Tokina they didn't list theem like Sigma. So I presumed Sigma is the first on to make 3rd party AF EF lenses.
