With sharpness and micro-contrast in mind, I have decided on the following: Olympus 12mm f2 Panasonic 25mm f1.4 Olympus 45mm f1.8 Olympus 75mm f1.8 I have the 25mm on the way. Will probably get the 12mm next and will receive the 45mm free from Olympus (offer with OM-D in the UK). The 75mm is aspirational as I would use it quite rarely, most of my shooting is in the range 24-50mm FF equiv. I received 12-50mm with the camera. Nice colours but not the sharpest tool in the box. waiting for the 25mm before I start to assess the camera. I used to have 25mm on a GX1, so have major respect for it. Do you guys think I have missed any other outstanding prime ? (I looked at the 25mm Voigtlander but it only seems to sharpen and contrast up at f2 which means that the extra weight and MF only over the Panasonic 25mm doesn't seem worth it, unless you specifically want the dreamy look at f0.95) - also what happened to focus peaking on the OM-D ? ... come on Oly!
