Having got a bit frustrated with the m43 PRO 12-40 f2.8 because of its lack of a longer end and remembering the old Zuiko 12-60, I took the plunge and ordered up the Panasonic Leica 12-60 f2.8-4 for a stiff wedge. First test vs the 12-40 seems to show the Leica OK, but not up to the Oly. Visibly less sharp at 100% on f8, both in the centre and edges. Must say I'm surprised because I'm used to even "toys" like the 14-40 pancake matching the 12-40 PRO. Anybody else tried it?
