lens assingment

Shoot a series of shots using the wide angle and the telephoto focal lengths of your lens. Your subject should be a portrait and you should frame the portrait as a "head and shoulders" type of shot. Keep the same ratio of head size in the frame in the wide and telephoto shots. Also shoot inside in low light with your aperture wide open and a low ISO such as 100 or 200 and then switch to 1600 to examine the difference in shutter speed.
