Which is better: Canon or Optimus digital cameras?

Canon. More reliable, especially the powershots. They're all good. Basically, get the most expensive A-series camera you can afford. Got $116.61? Get this one: http://www.amazon.com/exec/obidos/ASIN/B...
Got $246.88? Get this one:

And they start even cheaper than $100 (though I probably wouldn't do that), and go way, way up from there. :-)

canon

Canon rebel is a better camera....I worked in a camera repair shop, and that one was by far the best made, NEVER NEVER BUY a SONY, they kept us in business!!!!
especially the cyber shot, it's bar FAR the worst camera made!

canon definitley i took a picture of a fan in motion and it was like it was still

canon is number one in sales
that should answer your question
