As you browse through this and other sites, you will start figuring out some of the equipment you need for your studio. Some are essential, things you will need – Cameras, lenses, lights etc., and others are something you can do without for the time being – things you want. Try putting most of the things in the second list. You can always move them to the first list if you really need it.
You may find that your primary list has too many items that overrun your budget. You do have to be careful not to extend yourself financially. Do you really need all the three lenses in the beginning?
Much more details are available in the Studio section where the basic studio configurations for each type of photography are listed.
