With a variable angle view ranging from 99 to 61 degrees embodied by 7 circular diaphragms that assist in letting in more natural light without distortions. It's compact and lightweight design gives this lens a powerful punch in a small portable package. It weighs in at an amazing 1.07 lbs and measures 3.2 x 3.5 inches.
