E-M5 low ISO long exposure night photographs

Dear m4/3 users,

I would like to ask you to provide any low ISO long exposure night photographs (in full resolution if possible ) done by OMD E-M5.

I'm a long time GF1 user and I'm quite satisfied with my camera with an exception of long exposure photography at night (base ISO on a tripod). Despite the fact that I'm using dark frame extraction the images are still very noisy.

I'm torn apart between E-M5 and X-E1 and I have a feeling that if OMD E-M5 can take such photographs with relatively low noise I will just pull a trigger:)

Thanks a lot in advance!

Vlad
