Sanj, how could it do anything to IQ? It is a mechanical device outside of the row of elements in the lens, it is not optical.
The only way it would affect optics is if it doesn't work properly.
But really this thread is about a non issue. There is no IS vs non IS lens that Canon makes that would be equal, those that are close the IS version is superior to the Non IS version.
I don't know but am trying my best to understand!
I bought the X100 and asked the Fuji 'guys' about IS and this is what they said:
Hello Greg and Billy.
Great video, great camera! Mine will be with me end of this month...!!
Could you please educate me on one point:
Why is incorporating Stabilization into the camera a bad idea: Does it:
a) Increase costs?
b) Increase size?
c) Reduce quality?
Asking because I am sure ISO 400 results in better quality than ISO 3200 (which 4 stops stabilization would provide.)
I understand that u guys strongly believe that this camera does not require IS but my question is: HOW CAN IT HURT?

A) Yes, B) Yes, C) Yes as the ability for customization of the lens to the sensor would not be possible (well at least cost effective). I believe in I.S. however not so much with a 35mm equivalent lens. Especially the quality of ISO settings up to 3200 and a fast lens should allow for decent shutterspeeds for most situation. Others, use a tripod, or enable the flash.
