I have never owned a macro lens, but I often find myself wishing my lenses focused closer than they do and think I would really enjoy a macro. I have also considered alternatives such as tubes and add on close focus filters. Right now I'm not in the position to buy a macro, but maybe it won't be too long, so I looked at the Oly and Panasonic offerings and noticed the Oly is much cheaper. For those of you who use macros, is there something about the Panasonic that makes it worth the premium? I believe it has OIS, which would be nice as I use a G5, but I am someone who has to take the cost/benefit ratio seriously. Maybe in the meantime I could get either tubes or a close focus filter. Any recommendations on those? Thanks.
