I have always found the Lumix range of cameras extremely good, the image quality
you get from them is always good, having said that all of the options you have picked
out will be of comparable quality. It really comes down to which one you feel the
most comfortable with, so I suggest going to a camera shop and having a really good
look and feel of them all before you make your choice.
Best of luck.
I agree with the previous post. Panasonic Lumix are a great bridge camera with all the functions of a dslr. The model with a constant 2.8 aperture throughout the zoom range(I think the fz200) gives fantastic images. Earlier models needed more contrast in post, but the models now have great out of camera jpegs.
