Base ISO - What are the challenges in lowering it?
5 months ago

The majority of hype regarding a camera's ISO seems to be around the high end and manufacturers continue to raise the usable ISO range.  Fujifilm ASP-C sensor cameras currently have a base ISO of 200.  What are the engineering challenges of lowering that base ISO?  I understand what happens when it's raised, but don't fully understand why lowering it is not a much less challenging prospect.
