Canon PowerShot A640 Review
Compared to... Fujifilm FinePix F30
I thought it would be interesting to see how the A640 compares to Fuji's FinePix F30, still - despite 'only' 6 million pixels - something of a benchmark for compact cameras, and the undoubted champion at anything over ISO 200. Of course the F30 lacks many of the A640's controls, only has a 3x zoom and costs a lot less, but I would not be surprised if both these cameras were on many a shortlist.
In this section we have included comparisons at ISO 80, 400 and 800 (the A640's top setting).
Studio scene comparison (A640 @ ISO 80, F30 @ ISO 100)

Although the F30 is doing a fantastic job here (and being contrastier and more heavily sharpened it looks a lot 'crisper'), close examination shows that the extra four million pixels or so gives you a lot more to play with, something that will matter if you intend to produce larger prints, and the cleaner A640 image lends itself better to post-processing. I spent some time with these two shots and whilst you can easily make the A640 shot look like the F30 result with contrast and sharpness adjustments, if you resize the F30 shot to 10MP the A640 wins hands down. Again I must stress that this is only of any relevance if you are going to be pushing these shots to very large print sizes.
