Probably a repetitive question but my question is not so much as to which lens is better, but which would be the best choice for my situation. I have the OM-D E-M5 body (which I love) and I recently pulled the trigger on a GX7... Now I am thinking of selling some of my lenses and streamlining my collection. Obviously, getting one of the new offerings from Panasonic or Olympus makes a lot of sense to replace the slower kit lens (Oly 12-50) and perhaps sell the Oly 40-150 and a few other items. Having too many lenses seems to be a problem... Fewer, better chosen lenses might make my shooting much more enjoyable. Now, since I have both bodies (E-M5 and GX7) the question is which would be a better choice of lens? The 12-35 has the OIS built in which would be a plus with the GX7 and the 12-40 has the extra 5mm of focal length plus arguably better performance... Which would be the best one to have for my case? Thanks!
