ISO 200 - that's about the limit you can go to if you are one of those people who are worried by noise. Most users of this camera would be pleased with it though and would understand that the higher ISOs are only to be used in situatations where a trade off between image noise and low light blur issues (camera shake) is reasonable. It is here that Image Stabilisation is so important, offering a couple more stops at one ISO mark lower. If Fuji put IS on the next generation of this model it would have so much more going for it.
