Hi Andrew and welcome to the Q&A Board. You may need to stop down your aperture to get the best results. I usually set mine at f/22 (it also helps with the depth of field). A lot will depend on available light so you may have to shorten your exposure as well to get good shots. The good thing about digital cameras is that you can give it a try and if it doesn't come out quite right you can delete it and try again.

Here's a few
ctfalls of mine, if you scroll down and click on show/hide exif you can see my settings.
