Fuji F10's quality is relatively close to many low-end DSLR regardless of interchangable lenses. The quality of Canon SD400 and Nikon 7900 comes not so close to the quality of Fuji F10, considering the same lighting effect. You don't need that many memory cards since many affordable portable storages, something like Epson P2000, are now available in the market. The camera itself does matter. Purple fringing, in my opinion, has much to do with choosing the correct white balance. In addition, you can rectify by using the Photoshop.
I am looking at all these cameras. Here are my thoughts. I'd like to hear some feedback.
1. Fujifilm is an awesome camera and probably my top choice--I'm sold on the ISO 1600 (with little noise), the 6.3 mpg, and the long battery life, since I prefer not to use flash and leave the house for 20 hours at a time. Love the sharp Fuji colours too.
The Cons: Expensive memory card and purple fringing.
2. The "Elph" SD400 is a great camera, and just as light and compact as the F10, with seemingly the same quality of pictures. A great price, and a little sexier of a design than the F10.
The Cons: Lower ISO (400) and purple fringing too.
3. Don't know as much about the Nikon 7900, but I love Nikons (I have an F80 SLR) and this is such a good-looking camera! It's also the best-reviewed of the three cameras (7.8, by C-Net's standards). Affordable memory cards.
The Cons: The price! I'm looking for something between $350-$450.
Any thoughts on these cameras?
