CAMERAS – Digital Canon Cameras

I want one that takes as good photos as the canon eos 20d 8.2 mp.
Its kind of costly and I want to view my options.

Im a biginner im trying to find a good camera. Came a cross a Canon EOS 40D for a resonable price. Is it to much of a camera for a biginner, or is it a camera that Im going to benefit when I advance further in school. I also saw a 30D and a 20D. which one should I choose?

I am looking to buy a nice SLR, and I’m wondering which Nikon compares to a Canon 50D, speaking on features and specs. I really like the 50D, from what I’ve seen. I guess I’m somewhat of a beginner, as I have never owned a SLR. I’m only 16, but I’ve played around with my dad’s Canon 20D a bit, so I’m pretty used to the Canon system, but for my own I’m trying to find which the best camera out there is for me. I do a lot of macro photography, I like doing night photography, and I love taking portraits. Also, if you recommend either camera system, I need some help with lenses too, because since I have a range of types of photography I like, I definitely need a range of lenses
Thank you!

Argh. I forgot to format my Lexar Compact Flash card before using it. Now it won’t work with my card reader. I bought a USB Cable (because I apparently lost the one that came with the camera) so that I could download my images to my Mac. I installed the Canon EOS Viewer Utility software. When I open it, the camera is recognized (I see by the little icon), but it will not open the images. When I try, it says to check the connection…but, if I turn off the camera, it recognizes the disconnection. So, is the problem with the cable? (It says in the manual if you don’t use the one that came with the camera, there could be problems…) But, if it recognizes the camera, it must be with the card, right? But, I can see the images on the LCD screen. What can I do? I need these 200 photos of Istanbul!!! Please help!

I’m buying a camera but dont know if i should get an EOS 20D, 30D or Xti. Also a list of prices. thanks.
