Just got the PL45mm and 75mm lenses this month. Did a photoshoot with my littlest one last night. Absolutely amazed at the sharpness of these primes. 75mm has the magic of the giant aperture, but sharpness wise the PL45 is right there with the 75mm. Impressed at the bokeh of the PL45mm for "only" being f2.8. Here's a side by side at 50%, PL45 on the left. Color balance has more to do with lighting, so don't judge that. Remember these are heavy crops.
