There's a Taiwan user reported a similar case, his em5 died after exposed in a light shower. link
5D2, a33, D50, 400D - all survived. EM-5 which is splash proof died. So ironic. I bet all those owners would had laugh their ass off.
The TW owner say Oly TW told him that water went in from the bottom, the part where it is supposed to be in contact with the HLD6.
When i got my set, i also feel that rubber part is a little flimsy.how can contact points be so easily accessible. one small accident rubbing, one corner of the ru bber piece could easily come off and allow water to seep it. that is worse than no protection to me.
but i thot oly engineers might have thought of this and is good to go. but now, i think my intuition was right that this part can be problematic.
Perhaps its Oly way to get owners to buy the HLD6 so then it can provide a better splash proofing.
seriously, i bought the EM5 with 12-50 largely because it was splash proof. now, i am worried if it can even survive SongKran2013 or the kids waterpark in zoo, etc....
