Sorry Gary, are the two lens swapped (80mm<->90mm), I have no experience
with the Zuiko 80mm Macro but I think 90mm macro works better than the 80mm
macro at infinity. As Olympus does not design this lens (80mm) to work at
infinity and even up to 0.09 magnification (with bellows) is suggested as a
non professional method only, so the quality of this lens must be poorer
at lower magnification.
