Does anyone know what is the general view on using the lens hood? I couldn't find anything on searching and I'm sure Thom Hogan or Ken Rockwell would have a thing or two to say about it. Do I only use it when I'm outside in bright sunlight or when I'm indoors and there are bright lights that could introduce flare? or do I religiously use it whenever I have a lens that has one...which would be everyone except my 50mm prime? I can tell you one thing, they are a pain to carry around, because they take so much space in the camera bag. If the consensus is they don't do much I'll keep them in the drawer at home and make my life easier.
