Since getting my OMD in August I have grown to love mine and it is by far my most used lens out on the street, yet it has been seen by some reviewers as being somewhat lacking.
The 12-50 may be a little slow but I have forgiven Olympus for this, in whole there is a whole lot to like and used with care this is a very capable performer.
This lens has seen a fair bit of bad press, is there really anything to dislike.
