I have the Oly 14-42 which came with my camera. I'm actually ok with its sharpness from 14 to 30mm but it's not fast enough. I was thinking to get the Pan 14-45 which is sharp throughout the range all the way to 45, only $150, but still not fast. Now they have the tiny 12-32 coming which I'm assuming to not be as good as the 14-45, also not fast, and likely to cost $400. 12mm at the widest is a huge plus, however. As is the size. Or, I could sell my 11mm converter for $120, sell the 14-42 for $80, sell my Vivitar 28/2.8 for $40, and sell the Sigma 30/2.8 for $130 and use that $350 to help subsidize a Pan 12-35 f2.8 because if I had that I wouldn't need any of those (and I'd still have the 14 or 20 for when I need something compact). But then why would I pull that trigger when the Oly 12-40 reviews are coming. Ugh!
