If high magnification macro photograph is what you have been looking for, forget about buying a dedicated macro lens because your 18-55mm kit lens is good enough for the job.
What you need to buy instead is an extension tube and a reverse lens adapter so that you can mount the kit lens on the reverse for a super-duper magnification. You should also invest in a flashgun and a diffuser.
This is what I can conclude after watching this very enlightening video by Thomas Shahan on how to take high-magnification close-up photographs.
Although I might have understated the tricks he employed to his extreme close-up photograph techniques, I feel that this is the way to start for any beginner wanting to upgrade from shooting macro photographs using a point-and-shoot camera to shooting them using a DSLR.
