I gotta agree with Ruth here about the panasonic Lumix range, I've got two panasonic cameras, an FX5 with 12 times optical zoom and an FX55 which has facial recognition and is pretty good at shooting pics in low light, both cameras have automatic image stabilization which is handy when your hands are old and shaky like mine.
However.......
Its my firm belief that you dont need to have the latest state of the art camera to get the best shot possible. If for instance you take bad shots with your present camera, chances are that you'll also take bad shots with your new camera. Why not save yourselves a few bob and
find out if your present camera has got the ability to take good close up shots. If it has, then all you need to do is change the way that you operate it. It might be a whole easier than you think.
If you're unsure as to what your camera is capable of, just list the make and model here and I'll try and source some close up photos that were taken with the same model by someone else. If they can do it....well then, so can you.
