Could someone please tell me when colour fringing is likely to take place?
I was recently looking at a article in a magazine testing telephoto zoom lenses. In the article it said that the Tamron 70-300mm zoom lens just lost out to the Nikon 70-300mm zoom lens only because it produced slightly more colour fringing than the Nikon lens. It looks like the tests for colour fringing were taken at the widest aperture so is this when colour fringing takes place or can it happen at any aperture?
I do not use any lenses wide open as I am always after good depth of field. I nearly always aim to use a aperture of f11 or smaller so would either of these lenses stopped down still be prone to colour fringing?
Many thanks for your time.
