Thanks Eric for summarizing the differences between the S95 and the S8100. But this is information I had already seen at the the respective manufacturer websites and the side-by-side comparison on dpreview.
I guess what I was looking for, and did not appropriately ask, was what do these differences mean in practical terms when using the two cameras?
How much difference does the sensor (CMOS vs CCD and the size) make to the non-professional photographer? While I understand that a 28mm lens gives a wider angle of view than a 30mm one, how much of a difference is that? Is the difference in macro between 1cm and 5 cm really significant?
In general, I would be looking for a small camera that has good image quality, mostly outdoors, in some low light situations. I am not a movie guy (yet), I do like the ability to zoom in on occasion (especially for wildlife), and I like to play with the exposure to some degree to learn what effects it makes on the picture. I have not played with RAW image processing, and have never really felt that I needed to.
With those things in mind, is there a reason, beyond what the specs say as one might choose one over the other?
Ps: Sorry Paul, I seem to be causing drift from your OP.
