What lens would fit my Sony Alpha a200?

Question

55mm

Answer 1

Your Sony Alpha A200 takes autofocus lenses in the Sony mount.  Older autofocus Minolta or Konica-Minolta lenses should also work with your Sony.

Here's the current Sony lens lineup:

Do not get the older Minolta manual focus lenses (Minolta MC or Minolta MD), as they will not fit your Sony.

Also, do not get an accessory lens that screws onto the filter mount of your lens; those accessory lenses are cheaply made and will give you poor results.
