Fuji Finepix F80 EXR Indoor Crops

Below are sample crops from an indoor photograph of a book-cover at each of the Fuji Finepix F80's ISO settings. A crop from the Fuji Finepix F200 EXR
Fuji Finepix F200 EXR at the same ISO setting is shown next to the Fuji F80 EXR's crop. Images are all unmodified 100% crops from their respective cameras taken at the highest quality setting. The F80 EXR was set to P mode and 12 megapixels resolution, this is equivalent according to the manual to using Resolution-Priority mode.

These crops help determine which ISO settings can be acceptably used on these cameras. As noise increases, most cameras compensate with noise reduction which introduces softness. The result is that, while you can partly reduce noise at the expense of details, the maximum acceptable print size gets smaller as ISO is increased. The point at which a print become unacceptably noisy is a matter of personal taste.

Fuji Finepix F80 EXR	Fuji Finepix F200 EXR
ISO 100	ISO 100 - 1/4s F5 .1
ISO 200	ISO 200 - 1/4s F5 .1
ISO 400	ISO 400 - 1/6s F5 .1
ISO 800	ISO 800 - 1/12s F5 .1
ISO 1600	ISO 1600 - 1/25s F5 .1
ISO 3200	ISO 3200 - 1/50s F5.1
ISO 6400	ISO 6400 - 1/100s F5.1
ISO 12800	ISO 12800 - 1/200s F5 .1
The Finepix F200 EXR still has a very slight lead, maybe a quarter stop over its ultra-zoom sibling. Considering these cameras are so close in every other way, the lens range is most likely the deciding factor.
