The first all-in-one zoom lens to achieve wide-angle-to-long telephoto coverage (28-300mm equivalent) along with outstanding imaging performance, it's still the world's lightest, most compact 11.1X zoom lens in its class. Ready for virtually any photographic opportunity -family events, distant wildlife and sports action, compelling close-ups of the kids -it does it all without having to change lenses. Advanced Tamron technology -special XR and LD glass, Hybrid Aspherics, and Internal Focusing -is what makes all this possible in a dramatically downsized package. Cutting-edge internal and external multi-coating assures flare-free pictures even under challenging conditions. With specs like this no wonder it's Tamron's most popular lens. MOUNT COMPATIBLE SONY.
