Upgrade to lens

in my experience, standard zoom users typically go one of two ways -- more zoom range or more low-light capability ...
for the low light standard zoom route -- canon, sigma, and tamron all make a 17-5xmm f/2.8 standard zoom lens which is the widest aperture you can find on an aps-c zoom lens ... this will allow for better low-light performance and better subject isolation and background blurring ...
for the zoom range route -- canon makes a 15-85mm which is almost wide angle and almost telephoto ... people love this lens because it's suited for well-lit situations like day hiking or touristy stuff ...

of course, you can go even further down either path ... a tamron superzoom 18-270mm does very poorly in low-light situations and an f/1.4 low-light prime lens cannot zoom at all ...

different strokes for different folks ... for my first lens, i went the low-light route ... never looked back ...
