A1 upgrade from Oly C2100uz

[ToddNorris]

Has anyone upgraded from an Olympic C2100uz to an A1? I am thinking making that move and am interested in expereinces others have had. I am very pleased with the picture quality I am getting from the Olympic and would be happy to get that same quality with the added benefits of digital zoom (by having 5mp instead of 2mp), more gadgets like bracketing, the flex focus, etc and perhaps better low light shooting with a faster lens and higher ISO (even though quality suffers).

How does the ISO 800 shooting of the A1 compare to the ISO 400 on the Olympic. Do you get more light? Is the noise worse or the same?

How is your general picture quality using the automatic mode? As good as the 2100?

How much digital zoom can you get (on the PC) with the 5mp before the image degrades a great deal?

Any insights or samples would be great. I do not live in an area with a place that stocks this camera so I cannot really try it before I by it.

Thanks
