Originally posted by karrolann I am looking to upgrade my lens. Mostly for football (outdoor mostly night games low lighting) / basketball (indoor). I currently have a Tamron AF 18-200mm F/3.5-6.3 lens. I would like something a little faster and more zoom.
Please let me know if anyone has any suggestions on what lens would be the best.
Your Tamron is a good lens (I've got one), but as you've found, a little slow at the long end.
My alternative, for a "bit more light", is my Sigma 70-200mm f/2.8, which can be used with a 1.5x or a 2x teleconverter for 300mm f/4 or 400mm f/5.6 respectively.
Lenses that are longer/wider than your Tamron will usually be heavier, some significantly so, a point that may need consideration if that's likely to be a problem.
Good luck
