A simple test of whether a camera 'works' for you is to count the surprises, and see if the good ones outnumber the bad ones. Here is a case where I fully expected a fairly well-exposed building and a lot of silhouettes - and I didn't get that. As far as metering goes the F550 did a very good job! I was walking as I snapped this, so no points off for sharpness or composition this time :^)
Now on the other hand, you can see the oft-reviled lens' tendency to go kaleidoscopic - in this case it just seems to be a purplish halo, but in extreme cases it's made up of several colors. So while I will not claim this image is anything near perfect, I am more impressed than disappointed.
