Hi. My name is Gyroscope and I'm well known around these parts for asking dumb n00b questions. I'm really pleased with the macro mode on the 12-50mm lens for the OM-D. I can jam the camera right up in the face of wristwatch (maybe 5cm away) and happily snap away with (to me) pleasing results. I've learned that the camera needs to be on a tripod, but that's the only caveat. Yesterday I tried to use the 45mm prime for macro shots, and found that it refused to auto-focus anything closer than about a foot away, which is really too far away for what I'm attempting. Is this something inherent in the lens, or am I being dumb with the settings on the camera? Does the 12-50mm do something clever when I snick it into macro mode? Thanks in advance.
