I just jumped at a good deal on a used PL45, and am waiting for it to arrive on Tuesday. The choice is interesting between the two m43 45mm lenses (Oly versus Pana-Leica). They both appear to have very excellent sharpness, and richness. To my eye, a slight advantage may exist here for the PL45. The ability to shoot macro is a big plus for the PL45. The ability to shoot portraits at f1.8 of course goes to the Oly 45mm, probably a bigger plus. Size and weight definitely goes to the Oly 45mm. In-lens OIS could offer a slight advantage in some instances to the PL45. Lower cost definitely goes to the Oly (Although I found a used PL45 on eBay for not too much more than the Oly). In the end, I thought about the legacy Canon fd 50mm f1.4 that I love to shoot. The Oly 45mm would have been quite a bit of overlap for me. So, I decided upon the PL45 for mostly its additional macro capability. Now, just have to wait until Tuesday until it shows up at my work! I'm know I'm in the minority here. Anyone else either choose the PL45 over the Oly 45mm? Anyone have both? If so, why?
