In bright sunlight I have always used my lens hoods on my 18-200mm, 70-300mm and 100-400mm lenses and the pictures I get are dull, not very sharp, and sometimes darker. A month ago I was shooting in the early morning light without the lens hood and every picture was crisp, bright and clean. Yesterday I was out in the bright sun-light and did not use a lens hood, and again all the pics were crisp, bright and clean.
Anybody have an explanation?
