I’ve got an E-M5 also (same model as you). I don’t think I bothered with an LCP for this combination and shot. I am notoriously lazy in bothering with LCP and distortion correction unless it’s really bad or distracting. (I kind of like the slightly fishy distortion of un-corrected raws on the wide end of this kit for some reason). In this case I was shooting at 50mm, so the distortion was minimized on the subject…
If you don’t think it’s very good, you can always help out by making a better one and sharing it…
