One often over-looked accessory that is very important is the lens shade.
It not only improves image contrast measurably, but it protects the lens from
most incidental contact.  I use original equipment metal lens shades on all
my lenses. I must admit that the shade on my 24mm lens is almost a joke,
but the others are very important.
