Tamron SP 24-70mm F/2.8 Di VC USD

From the jury's assessment

The standard zoom Tamron SP 24-70 mm F/2.8 Di VC USD maps excellently also on the large full frame sensors from super wide angle to the light portrait telephoto. The continuous, large luminous intensity of 2.8 allows – together with the 9 aperture blade – a clear cropping of the image in front of a blurred background with beautiful Bokeh. Fast focusing and long shutter speeds are self-evident due to ultrasound drive and integrated stabilizer.
