Hi gang, It's time for me to enter the digital photo world. My Canon A-1 has served me well for about 15 years, but I'm thinking of moving on. Any advice is appreciated! My needs: Mainly travel and some sports photography. One issue that I have is that there have been times when I would have liked to bring the A-1 on a trip, but decided against it due to having to lug the whole kit around. For this reason, I am leaning more towards a pocket or prosumer model. I've used Canon all my life, and my dad's used Canon a lot longer than that. So I've mainly been looking at Canons; however I am open to other quality brands. I guess my main question is this: What are the pros and cons of getting, say, an S500 vs. a G5 vs. a Pro 1 vs. a D Rebel? What will I get for spending $900 on a Pro 1 instead of $500 on a G5? I haven't yet decided how much I want to spend, other than it'll be under $1000. It depends on what features are available at each price point. Thanks!
