This well-designed telephoto zoom effectively covers the most frequently used ranges. It's light (only 12 oz.) and short (3.4 inches) with a filter diameter of 55mm, making it a true ultra-compact zoom. Best of all, it delivers exceptional performance in situations demanding ease of maneuverability. Without eliminating distance and depth-of-field markings, it uses a two-ring rotary zoom/focus system ideal for autofocus cameras, with the zoom and focus rings widened for improved operation.
