in my opinion, the compact that i would downgrade to, would be the high zoom (400+mm) prosumer cameras..
this is so because the prosumer got very good quality at such lengths, and can record video !!!! with sound somemore !!! and in a small neat package..somemore the video quality for most of them is pretty decent
there are really really a lot of times when i wished i could switch to video mode using my d70s to shoot video... imagine a mother bird mouthing worms, and the baby birds opening the mouth for the mother to put it inside, and hear the sqwack sqwack sound.... wa kao the feeling is really shiok... sometimes photos really cannot replicate videos.
see how...if FZ50 price drop somemore to perhaps 600+ range, i may get it
