A solid performance here, but nothing to get too excited about – largely because cramming 61 million pixels into a sensor the size of a frame of film is going to have a payoff. From the native ISO of 100 up to 1600, results are good. There is an increase in grain at 1600, but it’s manageable and, more importantly, colours stay true. Head north of ISO 1600 and it starts to get more interesting. Grain is obtrusive at 3200 and very noticeable at 6400, but colours are still accurate. Once you get past 12,800, colours start to shift, with an increasingly obvious green cast appearing as you head to the maximum native ISO of 32,000. Grain is excessive in extended ISOs, with the top setting of 102,400 really offering very little pictorial benefit.
