These are a huge array of lenses that provide the best of the best within the Canon line for the basics and essentially the professional level as well. The 50mm f/1.4 USM is the nifty-fifty that is a must in anyone’s bag for the portrait look and feel. The 28mm f/1.8 USM is a sharp and edgy lens that provides the best in product as well as engine bay focus shots. The 17-85mm f/4-5.6 IS USM is an all around best use lens for the close up wide angle shots as well as the long distance telephoto captures that provides that extra grasp of your subject from afar. The 10-22mm f/3.5-4.5 USM gives the user that extra wide angle effect to the photos with the ability to reach the 22mm end without having to switch prime lenses all day long. 100mm f/2 USM allows the constant f-stop for additional aid in video yet amazing sharpness and bokeh in still photograhy. The 70-300mm f/4-5.6 IS USM continues that last bit of extension that the 17-85mm cannot reach. These are a mere suggestion of lenses for a collection and are obvious that there are many more options to choose from but by far this is the best of the best for the Canon APS-C crop sensor cameras that Canon offers.
