Even wide open, the Canon EF-S 18-55mm f/3.5-5.6 IS II SLR is incredibly sharp across the image. The image stabilization features really works, which delivers steady results. Unobtrusive, light and compact, the lens also offers accurate and fast autofocus performance. Unfortunately, some users reported that barrel distortion occurs at 18mm. If this is a deal-breaker for you, it could be necessary to invest a few hundreds dollars more on more expensive Canon L models. However, this shouldn’t be noticeable in typical real world application. If it does happens, some Photoshop tricks can fix this properly.
