My wife bought me a EOS 20D Digital last year for Christmas & I am a complete amateur. I just have the EFS 18-55mm lens & I would like to take pictures inside, but all pictures always turn out way too dark. I have changed settings on camera & have a Speedlite 420 EX flash bar, but still cannot consistently take inside pictures in mediocre light. Is there a good lens out there that will help me do this, & also be a good "tourist" everyday lens? I don't mind spending the money on good equipment, I have just been unable to get anyone to help me with information. I went to 4 different camera shops in NYC & no one could make a direct recommendation. If anyone could help me I would really appreciate it.
