Dispite all the helpful advice I received here I did end up buying the Kodak DX4530. Cost was the deciding factor. If I wanted 5mp that was the one I could afford. I would have liked the Canon - but it was double the price.
So far I'm very happy with it. The big advantage I've found is the clarity of the pictures in low light. I take photos of my paintings on the verandah, and usually then put them into Paintshop to adjust the brightness and contrast. I started doing that out of habit, and found that there was nothing to adjust. In most cases it was also not necessary to sharpen the image!
I also took some photos indoors at night with great sucess. In most cases the flash didn't leave reflections on the painting, and when it did and I turned the flash off the light from the flurecent in the kitchen was enough to take the close ups in this auction
All those photos were taken at night with no adjusting of the image in photoshop! I was very surprised!
I haven't had a chance to take normal photos in sunlight yet, but I feel that they are going to be outstanding.
The camera frame is light, the lens is a good one (I can't remember, but they raved about it - in one ear and out another with me - long words, couldn't spell them anyway!) and it has a lens cover which my old one didn't have. The software is easy to use, and as it's Kodak both cameras use the same cable and software so I don't need to change over everytime we download from a different camera.
It also takes movies, but I haven't found out how to get the size down under 6 meg yet. When I do you will see Coco at play
So far I haven't found any faults with it!
