If you purchased your Canon APS-C DSLR brand new, chances are it came with a standard kit lens, probably in the 18-55mm format. Though the user-friendly options make great camera lenses for beginners, they’re not without limitations.
The Canon EF-S 18-135mm f3.5-5.6 IS USM lens offers a vast increase of zoom when compared with the 18-55mm standard kit lens offerings, and incorporates image stabilisation and a faster, more sophisticated Nano USM autofocus system. This lens could be classed as an advanced standard zoom lens. Alternatively, consider a standard zoom lens, which is versatile and suited to general photography applications. Typically, these lenses start at a landscape-suited wide-angle focal length and zoom out to allow you to frame your portraits and similar shots.
