Hi, I have a Nikon D5000. I want to take some pictures of my baby and later on hopfeully do this professionaly. I want baby's full shots as well as close-ups of his toes, hands etc. I want to avoid using flash and lot of light on the baby. What kind of lens will be best? Will a 50 mm 1.4 be good for this kind of work? And can I add some sort of ring convertor to make it a macro to take toe /hand close-ups etc? The room space is small and not too big and that's why I think it rules out use of tele lenses. Thanks for your help.
