Wide open at f2.8. Not a lot of DOF in the image. But then again that's what I like in these images. The 135 also got me closer (35mm equivalent = 270mm). Took me a few tries to get this one also because the light levels were really low.
Note the E-PL1 coped well with ISO 400. A lot of people complain about the noise in the old Panasonic 4/3 sensor, but I don't find it particularly harsh in this one.
