That is clearly a misprint. The 7E/7G lens refers to the 21/3.5 lens---not
a 24/2. I can tell, basically, because I know the specifications of all my
favorite Zuiko lenses by heart. ;-) The 21's focus down to 0.7 feet / 0.2
meters, The 24's only go to 0.8 feet / 0.25 meters. (The 24 PC goes down
to 1.1 feet.)

John
