I returned a Nikon 50mm f1.8 series e lens and picked up a Nikon Nikkor 50mm f1.4 instead. I use it on a GF2 body, not sure if switching it over to my G5 would help with sharpness, going to have to try. I guess I had higher expectations from this lens, but I am comparing it to my 25mm PL 1.4 so its not a fair comparison.
One more image with this lens, again on a GF2. Converted DNG file to JPG, no other pp. I really like the images from this lens when I hit the focus, still learning on how to get the images quick with everything set on manual, will gladly switch lenses on my G5 between my 25mm PL and this lens if necessary after spending some time with it on my GF2.
