The article in Outdoor Photography is excellent - very clear and helpful. The Cambridge in Colour website is also very good.
This is an issue that is getting to me as I would like to achieve perfect sharpness throughout some of my images, notwithstanding what has been said about handholding in response to the post I wrote recently, and it seems to me that when handholding f/8 achieves the best results for my outdoor/mountain lens (17-40mm f/4L USM), but with a tripod (and mirror lockup/remote shutter release), I think that f/13 or f/16 may well give me more depth of field and sharpness throughout notwithstanding the potential minimal diffraction.
