All very true. In addition, according to the first reports coming in
on the Nikon VR 105/2.8 Micro, it does nothing for macro shots
either. The few stops of gain with stabilization is just not enough
and a tripod is still needed.
The other consideration is that focal plane stabilization is just not
as good as that built into a lens. It is just having to move too much
mass too quickly compared to the mechanism that uses optical elements
in a lens. The lens systems consistently get more stops of
stabilization. The focal plan systems undoubtedly up more battery as
well and the in lens VR/IS systems already suck up a lot of power.
