Because the "A" series gives you more modes and more manual controls. It also has somewhat better picture quality, although I don't know why - but I have (had) an A70 and my wife has an SD400 and we can take photos of the same subject at best quality and she'll have a few compression artifacts and I won't.

Also, I'm actually not sure if this is still true, but the use of CF at least used to also be a differentiating feature between the A and SD series of cameras.

Basically, in order of smallest/easiest to largest/most options, it goes SD, A, S, G series, then up to the Pro1 and finally the DSLR's.]]>Dec 19th 2005 12:18AMhttp://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/http://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/
The quality difference between the "A" and "SD" lines is because Canon has to use an inferior (though smaller) components in the "SD" line to make them in such a small form factor.

Every review of both product lines says the same thing. If style and size are important, pick the "SD". If image quality (though slight and possibly not noticible) is important, choose the "A" line.]]>Dec 19th 2005 12:18AMhttp://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/http://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/Dec 19th 2005 12:18AMhttp://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/http://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/Dec 19th 2005 12:18AMhttp://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/http://www.engadget.com/2005/08/22/the-canon-powershot-a620-a610-and-a410/Dec 19th 2005 12:18AM
