Hi Spirelli, thanks for your message and welcome to Cameralabs. I'm pleased you are finding the reviews useful.
Yes, the FZ50 has quite high noise, especially above 200 ISO. If you regularly shoot above 200 ISO and either make big prints or enjoy viewing on-screen at 100%, then you may be disappointed.
Similar cameras at a similar price point include the Fujifilm S9500 or S9600 (S9000 or S9100 is the US), but again they don't perform great at very high sensitivities. This is a problem with most compacts and all-in-ones because their sensors have a relatively small surface area.
If you want low noise at high sensitivities, then you need a DSLR, but you don't necessarily need to go for a brand new model. Older DSLRs are much cheaper and still offer great low noise performance. One of the best deals is the Nikon D50 - see our review here and check out the typical prices at the bottom: www.cameralabs.com/reviews/NikonD50/
It's pretty good value for what you're getting, although you would need to spend more on a lens with a bigger range. You may find the basic 3x kit lens more flexible than you think though...
Hope that helps!
