Can someone explain the reasoning behind limiting the shutter speed to 1/1000 in A mode?

There are plenty of cameras which do it. It's a mechanical function, limited because of the amount of shutter movement required to expose an f2.0 lens at high speed

On the X10 you can manually adjust the shutter to 1/4000.

Some folk who haven't tried it claim that the exposure will then be inaccurate. I have posted images with exposures at 1/1000 and 1/4000, with matching ISOs of 100 and 400.

The images show identical exposure levels in the middle range - because they were both over-exposed (f2.0 is too wide on a bright day, even at 1/1000 and ISO100) and so I feel that the higher shutter speeds are still accurate.

The example shown in the X100 review does not seem to affect "real" images.

You get good exposure if you want at 1/4000 f2.0

but what you don't get is real f2, because the shutter doesnt open completly, and you have the bokhe of f4

try it
