I'm on the market for a entry-level digital camera that still allow a high degree of customization as I grow in experience. My previous camera is not digital (Canon EOS-10) so I have no experience in that sense. However, I do consider myself at a moderate level of experience when it comes to photography, so I need my digital camera to refrain from behaving simply as a point-and-shoot type of camera.

With that in mind, I've got the following cameras as candidates.

Sony DSC-W1
vs
Fujifilm E550
vs
Canon A95

Specs-wise the Fuji is the most impressive, featuring 6 MB as well as a variety of advanced features.
Sony, on the other hand, has a very good lens, while the Canon is being considered simply because it received good reviews (specs-wise it's the least impressive).

So which camera should I get?

Also, if you've got suggestions, please do feel free to share them (I'm looking for a camera in the $500-600 CDN range)

Thanks!
