Hi Moose! Love the site, bought a couple of cheat cards, and look forward to your suggestion for me.
I have a Canon 75-300mm and a 50mm f/1.8.
I'm a teacher and my director said there are some extra funds if I'd like to purchase a new lens (I am also in charge of the yearbook and I take all the sports events photos). I think my 75-300mm is great for the outside sports (I do use the Tv setting just about the same as on your cheat cards), I just have trouble with the indoor ones (volleyball and basketball). I also take lots of portraits shots at events and group team pictures. What new lens should I purchase? She's allowing me up to about $500. I was thinking of the 50mm f/1.4. The 50mm lens I feel already forces me back quite a bit for group/team photos, so I don't think I want to be shoved back any further. Will the 50mm f/1.4 be much of a difference from the 50mm f/1.8 I have? Any thoughts or suggestions since I have this "free" money coming?
