better or worse than the 450D?

- Big improvement in sensitivity. I find that noise management is very good. The photos are stunning at 1600iso; above the noise starts to appear but it is reasonable. In general, the new sensor really brings a plus.
- I preferred the handling of the 450D, position of buttons and operation, but it's really a matter of habit.
- What about the video? It's a little gadget but it's nice to both other. The quality is good but the autofocus is not good and very noisy (and you can hear on the video of course) so I make manual focus in video. It takes some practice since the device's grip is not suitable. Another negative point of the video, and live view in general (if not ultimately useful) is that it drains the battery at full speed. If you use more stabilized zoom, prepare spare batteries.

In conclusion, I am satisfied with my purchase, but disappointed with the live view, and rather amused by the video but it does not replace a camcorder.
