Wow. This sounds like a pretty nice camera. If the image quality and low light capability come through it would prove to be a good all around camera. Max f2.8! Pretty neat.
I had an FZ30 as my main camera a few cameras back. It was decent but I moved on to DSLRs since then. I wouldn't replace my DSLR with the FZ300 but, if I had the extra cash, it might be a great addition to my collection of cameras.
Wow the specs and price on this Nikon look really good. It will be good to see the full review. However...
All 4 cameras in our house have viewfinders. My wife and I simply won't buy a camera without one. There are times when the LCD simply won't do the job. An EVF would be perfect.
Perhaps Nikon will consider putting a viewfinder on the next model if they see sufficient comments like mine and so many others here.
