Conclusion - Cons
- High ISO performance worse than 40D

- Per-pixel detail not as good as on good 10 or 12 megapixel cameras

- Poor white balance performance under artificial light
- Flash must be up for AF assist lamp (although AF is good even in low light)
- Live view not as accurate as on 40D (framing very slightly off-center, in contrast detect AF mode not possible to magnify right out to the extreme corners)
