I've been using the small point and shoot digital cameras for about 5 years now, and I love the small size and portability of my cameras. But the auto settings are a hindrance for me. I'm ready to move up to a camera that has more features - manual shutter speed, aperture vs. shutter priority, that sort of thing. What should I look at? I dont want to go back to a big gear bag and multiple lenses. Thanks for any advice.
