Hi, i have a Sony A200-dSLR and the stock take good pictures but i love depth of field. the more DOF the better. so i'm looking for a lens that will give me the most possible, it doesn't have to be a zoom lens, i looked at a 55mm macro lens that really didn't do "macro" very well and just seemed like a normal lens. i had to move up to 110mm before i could get close to anything. anyhow, could anybody suggest lenses for me? and show some examples of what kind of pictures they take? i'd also like to get some filters for my lenses, for example i want to learn to take pictures like the movie "children of men" so just suggest macro, non-macro, and filters, and i'll see what i like.
