I am pretty disappointed with the low light performance and sometimes autofocusing a bland scape like clouds or sky. I have tried with high ISO and lower shutter speed but the noise is ridiculous and focussing (I am using XF70-300MM). If I had waited or a month I would have got this camera for 10K less which is pretty disappointing with i see the price. That probably would have been the right price for this camera. I am happy with colour profile and the image quality during sufficient light.
