Using a rounded diaphragm*4, the lens achieves gorgeous blur effects.

*1 For high-speed standard zoom lens compatible with full frame size SLR cameras except with Sony full frame size SLR cameras. Current as of February 2012. (Source: Tamron).
*2 USD (Ultrasonic Silent Drive) is Tamron's proprietary ultrasonic motor drive.
*3 The Sony mount does not include VC, because the body of Sony digital SLR cameras includes image stabilization functionality. The product name for Sony cameras is "SP 24-70mm F/2.8 Di USD" without the VC designation.
*4 This rounded diaphragm retains a nearly circular shape even when taken two stops down from its fully open state.
