Nice portraits. I like the way the first image shows all the fine detail from the subject's face and at the same time, even from his fingers which are way off-center.
The second one seems to have focus issue (more on the left shoulder, rather than face?) but I would not have imagined shooting a 6400iso for an image like this even a few years ago.
I only have the kit lens with my e-pl2, but this lens seems an interesting option to consider (even though I am currently torn between the 45mm and 60mm!).
Thanks for sharing.
