Lenses at the Shanghai Auto Show definitely test both sides of the envelope. Some photographers came with lenses long and wide enough to take close-ups of concept cars shown on the moon.
This photographer usually shoots big game in safari parks and only moonlights at the car show. Or maybe he#s the one who does all those spy shots.
Many members of the accredited media (the vetting process is hard and rigorous, nonetheless, press days are mobbed) must be in the live blogging business. One sees more and more cell phone cameras for a direct beam-up to high traffic websites. We hope.
