Helium2, welcome to posting!
I don't know your specific subject interests for macro and close-up photography. But let me suggest that you strongly consider buying a dedicated, long-focal-length, standard "macro" lens. (I put the word "macro" in quotation marks because this use of this word has made pedants argue--but don't worry about that.) A longish lens that focuses from infinity to 1:1 is an incredibly useful optical multitasker that will ease your entry into the world of photographing small subjects, and that will continue to be an imaging workhorse even if you go deeper into photography of even smaller subjects--even if you acquire expensive, specific, exotic optics and other tools. I'll bet that most of us here who have lots of optics for high magnification also have a good, general-purpose macro lens, and make frequent use of it.
Your camera has a "crop-frame" APS-C sensor with a 1.6X crop factor, so a macro lens with a focal length of 60mm will likely serve you well. (Speaking here from experience about what seems to work in life.) It will have equivalent coverage of an approximately 96mm lens on a full-frame camera. I live in the Nikon world, where 105mm is a standard macro-lens focal length, and find this a sweet spot for a wide variety of close-up work. The moderate "longness" of such a lens lets you stay back some distance from your subjects, which is helpful in for lighting your subjects, keeping some distance from bugs, and shooting with a pleasing perspective.
When I was in university, I first started getting close to small photographic subjects. I was on a tight budget, and tried diopters (aka "close-up filters," of which the Raynox offerings are current examples), bellows, reversed lenses, and other things. I found none of these fully satisfying. But when I scraped together my pennies and bought a dedicated macro lens, my images, and experience shooting macro, made me think: "Where has this macro lens been all my life?"
Years later, I continue to find that having a really good, basic, infinity-to-1x lens (aka, a "macro lens") gives me a useful, versatile, tool. Today, I shoot from infinity to 100x, and have lots of expensive optics dedicated for specific slices within the range of "small." Still, my trusty 105mm, infinity to 1:1 macro lens is perhaps my most-used lens. I doubt many photographers regret buying a solid, basic, longish-focal length standard "macro" lens--no matter how sophisticated they get.
Best,
