Quite a decent lens. As a replacement for a staff member, it is very worthy. Was earlier 18-135 Canon. 24-105 heaven and earth, much better. Sharpness is on the level, but here it often depends on the photographer. You can achieve very high quality and interesting bokeh (50-70 mm focal length), but you need to experiment like with all lenses. I like him. Its pros: Constant aperture,comnstructive, bokeh (at some focal lengths) (see, for example, ), fast autofocus. Has cons: Aperture is sometimes not enough, you have to use a tripod or flash.
