Product Information 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. The ZEN finish helps prevent reflections and is designed to withstand the demands of tough environments. Bayonet-type lens hood is included.
