Since getting back into things, the kit lens that came with the Canon M50 is nice, but I def need more. At first, I was looking at the 24-105L but remembered a couple of older Sigma lenses that I was interested in back when I had my Canon 40d. The Sigma 17-50 and 50-150 f/2.8. The used price on them all is very good. I will mainly be doing indoor flash stuff for a friend's website (picture of products) and when I get out landscapes and really whatever else. This time around is all fun for me. Not ready to buy into dedicated EF-M lenses just yet. Wanted to keep a nice simple 2 lens main setup, because for vacations I can always rent something longer to use.
Would those older Sigma lenses still be a good choice these days? I live on a disability budget so most new glass is out of the question. Other lenses to look at? I know I could get some brand of a 24-70 and 70-200. But my price range is in the ballpark of $400-$500 per lens.
