Thanks for the advice, Marcel. I appreciate that you made a specific lens recommendation. "Sports Illustrated" images are WAY beyond my dreams (experience / equipment level). I'd settle for a few "Spuds Illustrated" quality pics. (Idaho potato growers quarterly mag.) I did some quick research, and am wondering about the Nikon AF FX NIKKOR 85mm f/1.8G. What do you think about it? Any recommendation on where I might pursue finding a good used one? I can't afford a new one, right now. But, I could definitely keep my eye out for a used one, if you think it's a good option.
Here's an example of what I'm getting with my current lens (55-300), which doesn't seem too bad, as long as the light is VERY good. Another grandson passing. (I don't use the auto-focus for freeze action... too slow.)
