I went to a flea market today and brought my X-Pro1 along. This was an amazing place!It was also a great place to test the high iso of the camera, and I can only say I am hugely imressed.
Canon 5d mark II did not do a better job when it comes to high iso.
My last camera the Canon 1ds mark III would not have a chance!
I also find that with the latest firmware, there is hardly any focussing problems in the dark.
That camera is awesome...
All shot with the 35mm f1.4.
