The Tamron SP designation is reserved for lenses developed with special emphasis on extraordinary photographic performance. Engineers are free to innovate in an uncommon atmosphere where optical performance comes before price, resulting in lenses that satisfy the demands of discerning photographers.
Fast becoming a benchmark for this category, the SP 70-300mm F/4-5.6 Di VC is an ideal choice for a two-zoom system—complimenting a wide-to-moderate-tele zoom perfectly. Delivering class-leading sharpness, brilliant color and striking contrast, discriminative APS-C and full-frame digital SLR photographers alike are quick to laud its performance. The first lens to feature Tamron's USD (Ultrasonic Silent Drive) auto-focus drive mechanism and VC (Vibration Compensation) image stabilization, these proprietary technologies are teamed with XLD (Extra Low Dispersion) and LD (Low Dispersion) glass in a 17 element, 12 group formula. APS-C-sensor photographers will enjoy extreme telephoto subject magnification, with a resulting picture angle range approximating a 109-465mm lens on a 35mm film or full-frame DSLR. Sharpness, enhanced by Tamron's exclusive tri-axial VC image stabilization is amazing. Combating blur from camera shake, Tamron VC enables shooting handheld at as many as four shutter speeds slower than would be possible otherwise. Full-time manual focus makes fine tuning easy.
