The numbers are in the reviews and are based on technical information from Ricoh Japan's Web site. Edit: Not all reviews include the numbers. I am checking the Ricoh Web site's claims and am wondering it the numbers quoted here are from press materials.
It is important to note that those numbers are CIPA certified* using outside CIPA-approved outside laboratories. I don't know what the current situation is, but at one point the full CIPA requirements were available online. The make for an interesting read.
Now whether 4.5 stops of SR is enough to overcome 8 stops negative input from the user is another matter.
