Hi Grumtatt, welcome to the Cameralabs forums.
Noise aside, the FZ30 was an excellent camera, and thanks to the effective OIS, you could take most of your photos at low ISOs anyway and avoid the noise.
The FZ50 promises lower noise, but remember it squeezes in more pixels, so it will certainly be interesting to see how it copes. I suspect the noise reduction could be more aggressive, but will only find out once we do a full review.
Speaking of which, I've already played with the FZ50 and have some sample images at different ISOs, but am waiting to hear from Panasonic about the software version of that particular model before posting.
If you get hold of one, we'd love to hear what you think. Let us know in the Forum, or if you have a camcorder, why not consider putting together a brief 2 or 3 minute video going over what you believe are the good and bad points. Then upload it to www.youtube.com
so we can all see it...
for our first attempt at a video overview.
