Title: 5D2 and telextenders
Post by: stever on May 04, 2009, 10:38:57 pm
i'm pleased that the 5D2 microfocus remembers the combination of lens and extender (and pleasantly surprised that it remembers non-canon lenses, aparently by focal length)

however, resolution seems to be proportionally more degraded by the use of the extender than with other bodies  -- and the focus interaction of the extender varies from lens to lens.  that is, the same extender requires a plus correction on one lens, but minus on another

what's going on?
