General purpose lense, is lenses with range 18-50. This lens have fairly good wide while able to do zoom. There also normal lense with wider range, but these lenses could weight our camera bags, plan a head.

Macro Lenses, is nice a must to have. An 50mm f/2.8 is great to capture small things. You will be stunned seeing the result, small things has never been this interesting captured with macro lenses.

Telephoto zoom, these kind of lenses is good for professional photographers. The fast lenses in this range could weight more than you could handle and sometimes it’s too advanced for beginner. Budget is also reason you would stay away for these lenses in the beginning, as you develop the skill your time will came when you need this range of lenses.
