ISO 100 and RAW

[esanchez]

Today I realized that the X-T2 supports RAW using ISO 100. The X-T1 only gave you a jpg using ISO 100. My question is any reason to use ISO 200 when you can use ISO 100 with RAW support?

ISO 100 is an expanded ISO. It's just like taking an image at ISO 200 (over exposed by 1EV), then adjusting the exposure by -1EV in your RAW processing software (only the camera does it for you)---meaning you'll lower the noise floor, but you'll also probably have some blown out/unrecoverable highlights. Does that answer the question?
