The original Tamron SP (Super Performance) lens is rich in features, with VC (Vibration Compensation) and USD (Ultrasonic Silent Drive). High-quality glass includes three LD (Low Dispersion) elements, three Glass Moulded Aspherical elements, one Hybrid Aspherical element and two XR (Extra Refractive Index) elements. The well-rounded aperture is based on a nine-blade diaphragm, helping to retain good bokeh when stopping down a little.
Image quality is very pleasing, with impressive sharpness and contrast, along with a creamy softness in defocused areas. Distortions and colour fringing are well controlled, throughout the entire zoom range. Autofocus is fast, whisper-quiet, and fully internal, so the front element neither extends nor rotates during focusing. The lens does physically extend at longer zoom settings, but a zoom lock switch helps to avoid accidental extension.
