Tamron SP 24-70/2.8 VC @50f4.0 58091
Tamron 24-70f2.8 VC shot on D800 on a tripod, VR=OFF, contrast-based AF. Developed from RAW in Lightroom 4.1 at Camera Standard settings apart from sharpening at 70/0.5/36/10 and NR=OFF, CAred=ON. As this copy of the lens has a defect all apertures (apart from f2.8) are recorded 2/3 of a stop smaller than they are effectively.
