Before we discuss about the performance of photo lenses on "Sharpness" and "Resolution", we should pay attention on the circumstances of the experiments, "Subject blur" and "Camera shake" are the subject to be avoided so absolutely.
The image stabilization technology in both lens and camera body has been remarkably improved these days, some desperate efforts by the engineers must exist behind the announcement. This kind of tendency is the climinal to form the mountains of deserted tripods. It's a matter for regret that famous ones are sold at nothing in the Auction!
But remember here, we can see the difference between the effect of Anti-camera shaking compensation and mechanically fixed on the stout tripod, if we compare the resolution by enlarging pixel level.
However sophisticatedly camera shake phenomenon might be compensated so fairly, the picture obtained in handheld condition is completely different from that in mechanically fixed image sensor.
So far the camera is held by hand "Blur phenomena" could not be compensated as to overcome the long lasting ancient "Tripod" at all.
Any announcement in a loud voice of Pseudo, misunderstandings of prayers, curses and spells would never be accepted by the Principle of Science.
Don't expect too many success stories from a single photo opportunity. Don't be greedy and omit a tripod. Don't be afraid of weight or umbrella tension. There's only one absolute success.
As a conclusion, we should never desert our marblous "Gem Tripod" if we aware a photographer.
