Hello, newbie here. Gary is my name. Warmest regards.. Noticed tonight that the OM-D E-M10 camera can be had for $399 on Amazon now. I am quite new to the OMD and noted that it is much smaller than the E-300 I have now. Is the E-300 a "micro" 4/3? Is that the difference in the size camera and lens? I love the reviews on preview and will likely get this camera in the near future. Are there any comments as to a good macro lens, or a news that doubles as a macro? Love crystal clear close up work.
