I have a Sony Cybershot DSC-H7 8.1 maga pixel camera. Im considering buying a macro lense for it so I can take pictures of my shrimp. As far as what lense to get im sorta lost, so can someone more educated on the subject recomend a lense for me. The pictures are just for my own amusement and dont have to be the best macro shots ever, so I dont necessarily want a real expensive lense. More or less one that will get the job done. Im just looking to pick up a little more detail in the shrimp. Any ideas?
