I took this photo of a traditional Chinese "junk" in Hong Kong harbour. The photo gets darker in a circular pattern around the edges, and I'm wondering why this is- I like the effect, but is it a limitation of the lens, something I can control or just a normal aspect?

Thanks!

It's called "vignetting" (http://en.wikipedia.org/wiki/Vignetting) and it's almost certainly a limitation of the lens, and it's fairly common. I think you can control it by widening the aperture a few stops but I'm not certain.

Yeah I thought it was an example of vignetting. I'm surprised its so pronounced, although like I said I don't actually mind the effect- it frames the subject quite nicely! I'd be interested to see how similar the vignetting would be using, say, the 18-200mm lens rather than the 55-200mm at the same zoom length.

Yes, it can quite often look quite good and can draw attention to the subject and sometimes people deliberately add it in afterwards. Of course, there are times when it doesn't look as good, but it can be removed using image editing software such as photoshop.

You can removing vignetting easily if you process through Capture NX.

It can be down to the lens but it can also be caused by lens filters too.
