Thanks for the info. I use mine with the same combination.
You can of course add my "lego hack" to add macro. I asked several times here if the macro gear fitted, but got no answer.
I've now bought it. It is sufficiently long, but the macro must be thinner all the way, so the hole in the gear is too thin.

About the 12-50, why would you use it without macro?
I have an e-pl1, 14-42(I), 14-42(IIR), 12-50.
On land, my 14-42(I) is clearly the sharper of the three. It seem like geometric distortion is not/not fully corrected in it. It has the shortest focusing distance. Movies are not really possible, and focusing time is double of the other two.
The 14-42(IIR) is blurred in the corners, and has a longer minimum focusing distance.
The 12-50 is slightly less sharp over the full surface than the 14-42(I), and minimum focusing distance is clearly longer. The advantage is macro, movie and faster focus.
This is the case with my actual lenses and my e-pl1. I'm in the process of finding a pattern of the blurryness of the 12-50 (which was the same before the mod, btw). If it depends on the image stabilizer etc.
So I'm interested in hearing about your experience with that lens/body combo. I got no feedback on my requests on the matter on the m43 forums.
