LZ, your photos are persuasive evidence that good picture quality can be obtained with this lens. Are the shots you've shown shot from tripod, handheld using VR, or both?
. Since VR was implemented, have never used tripod outside. Handheld VR ONLY, with supporting for elbows, as the night image of Manhattan at 1/8, as VR in this lens is a blessing! On speeds range of 60-180, VR is on "Active" position, to avoid VR-shutter-mirror wrong mechanical vibration, caused by engineering mistake of D800-810 mirror boxes. At this position, the lens is fantastically sharp, no double lines at all. So I left the "Active" VR at any speed, it nicely working for me. Thank you! LZ
