Phoblographer posted an informal comparison between the Fujifilm X Pro 1 and the Sony Nex 6. He compared both cameras in landscape shooting. The image samples you can watch on phoblographer show some differences. The first thing we recognise is that pictures on the Sony Nex 6 look warmer than on the Fuji X Pro 1. Phoblographer notices also that “at the same exposures the X Pro 1 will retain more detail in the highlights but the NEX 6 will retain more information in the shadows”, and that pictures taken with the X Pro 1 look sharper.
