[OM] Re: new models?

[Chuck Norcutt]

I don't see how.  The way digital image stabilization works is to allow 
the image to float across the surface of a sensor somewhat larger than 
the image area and capture the image area wherever it happens to be. 
How you tell where the image is supposed to be I haven't a clue.  Maybe 
accelerometers?

Next has to do with the sensitivity of the sensor.  As the image is 
skittering across the sensor surface eventually the shutter button is 
hit and it's time to capture.  Is the sensor fast enough to do that?

Let's use some hypothetical numbers.  Assume a 9.3 MP E-3 sensor with 
2700 x 3600 pixels.  (nice round numbers, I just made it up).  Using the 
14-54 lens at 54 mm the image covers 19.1 degrees horizontally.  If the 
camera is rocking horizontally at a rate of 10 degrees/second (another 
number I just made up... but it seem reasonable) then the image is 
skittering across the sensor at a rate of (10/19.1) x 3600 = 1884 
pixels/second or 1.884 pixels per millisecond.  Does this mean that 
stabilization only works at very high shutter speeds?  Seems that that 
problem has already been solved by none other than high shutter speeds.

What's wrong with this picture and my calculations?
