K2 Pro uses the same sensor as the standard E2 which is at 4.63 µm grade. Each sensor cell is 54% larger than the Sony A7R IV, that is how we get these smooth footage even in extremely low light situations. However the large sensor pitch size shall inevitably limit the output size. The iZugar MKX200 fisheye lens is tailor made for E2, and it is perfectly match on the 2772p 4:3 mode. After unwarping the native output resolution is at 5.5K. We prefer to export as 5120×2560@60 for high frame rate content, or rescale to 5760×2880@30 for mono for distribution. Anyway the iZugar MKX200 fisheye lens is very sharp from edge to edge, scaling up a bit or even to 6K will not have obvious impact to the final render quality.
