I dunno. I find pictures taken with my Olympus C-2100UZ to be plenty sharp at
full zoom (equivalent to 380mm in 35mm cameras) handheld. Perhaps there are
sharper cameras out there, but it is definately great IMHO.


It is optically stabilized though, isn't it?

A good test to see if the lens is sharp enough for the sensor is to run
a USM filter on a well-focused image with fine detail image at native
resolution, set the strength to about 300, and see what the smallest
radius is that has a big effect. If 0.4, for example, has very little
effect, but 1.2 has a big effect, then the image is resolution-limited
by the lens, and not by the sensor.
