120fps slow motion territory is where things get expensive – the Sony FS7 is about £6K+ or $9K in USD, and out of the budget for most NX1 type shooters. 120fps in 1080p HQ mode renders the best slow-motion that $1500 can buy today. He does point out that Full HD suffers from heavy aliasing, due to the pixel-binning required to get the 1080p image from a 28MP sensor. In 1080p mode the rolling shutter is even less, again without a crop. On the other hand, the Samsung NX1 has no field of view crop and does a 6.5K readout. Andrew points out the fact that Canon 1D C and the GH4 have a little bit less pronounced skew is due to the crop in 4K that they do, which saves time as they don’t read out any more pixels than they have to. The NX1 with its 28MP APS-C Sensor has a staggering amount of lines to read at 24fps or 30fps. Not as big of a problem as some might have thought – comparable to rolling shutter on the Canon 1D C in the real world and Sony A7s – which has a full pixel readout on a 12.2MP sensor – more than twice as less pixels as on the NX1.
