EF and not EF-S?
A claimed sighting of a prototype new Macro. An EF 60mm f/2.8 Macro IS. The tipster may have meant EF-S.
We’ve already seen a patent for the 60 Macro with IS.
A separate source has said to expect to see the new Macro with a 60D announcement.
New Macro to the Lineup?
The same source says Canon engineers are working on a Macro with the hybrid IS that is longer than the current 180mm f/3.5L. That macro lens would remain in the lineup.
Don’t expect this macro anytime soon.
