Hi! I currently have a Fuji 3800 and love it, except it is too big to be useful while travelling. I am interested in an ultracompact that takes great portrait shots, and especially night shots with lots of bright lights since I have upcoming trips planned for Las Vegas and New York. Possible cameras I am looking at are the Sony DSC-W1, Sony P-100, Kodak LS743/753, and the Canon S500 and S60. I would really appreciate it if anyone here could give me feedback on the quality of night pics on these cameras or if there are any others that would fit the job. I am interested in 4 or 5 megapixels. I would prefer adjustable manual settings, but would purchase fully automatic that takes great pics! Thank you so much.
