In a previous post, many recomended I upgrade my lenses rather than camera body. I have a Elan IIE and I have started looking for lenses. I enjoy taking pictures of sports, people, and I tend to have a ton of shots of our dog. Does anyone have a good 28-70 or 28-105, Canon lens recomendation. I have a Tamron 28-80 right now, which has been great to learn on, but I'd like to take the next step in photography.
