There was a topic already with some shots taken by many people with the XC 50-230, but I could not find it today. I took my XC 50-230 for a stroll this past weekend, something I had not done before. I've had the lens for a while but did not have a real oportunity to put it to the test.
So, my conclusion is that it is a pretty good lens, and if you need that extra reach, but do not want to spend all that money on the XF 55-200, you can get the cheaper, lighter and longer reach XC 50-230 with no worries and regrets.
Here are some examples:
First. Check out that reach!
At 50MM (notice the Seisho-no-ie holy grounds to the left):

AT 230mm. Well...that got close enough, and sharp enough, for me.

Now a couple of closer look shots of that sail boat: (go to flicker and zoom in. pretty sharp I think)

Another at 230mm. This one testing out the image stabilization. I was in a moving vehicle when taking this shot of the pretty lady riding her horse.

Another at 230mm also in the moving vehicle.

Well, what do you think? Good enough?
