And, as mentioned, the 24mm Shift and 20mm f/2 Macro Zuiko, but not the
40mm f/2. The 40mm, as well as the 1.4x teleconverter have "low
dispersion" glass, not extra low dispersion (ED). A look in the glossary
of the Olympus OM System Lens Handbook reveals that Olympus considered
what they call "ultra low dispersion glass" to be what we typically see
as SLD or ED in today's marketing hype.
The FAQ needs updating to include the 20mm.
