I have been thinking about it arriving next year and how it should be differentiated from the current lineup. First, it should be more than 45 mp. The Z7, Z7ii and Z9 already cover that. So it should be in the range of 70 to 100 mp. Second, it should be focused on portrait, landscape and studio work (traditionally medium format territory). Notice that medium format cameras don't now feel, and have never felt, the need to copy the old 35mm film format. Rather, they tended to follow either the square format or the old 5x4 format. I would like to see Nikon "freed" also from the 35 mm film format in the Z8. Third, I don't know the circle of light projected by current Z lenses but it must be large enough to cover the long end of 35mm so therefore it must be good enough to cover a width of 36mm. Why then limit the sensor to a height of 24mm? The circle of light must be good enough for a 36mm square sensor, even if there is some falloff in the corners. West End Photo suggested this on NR many years ago. However, I suggest something a bit different. I suggest Nikon work with a sensor format that is the old 5:4 format and simply fit the Z8 with as large a sensor in that format as they can fit into a Z mount body. Call is "Medium Format Lite." Shorten the width, increase the height and simply make the entire sensor larger with as many megapixels as currently possible. Make the Z8 a cheap competitor to the Fuji GFX bodies and the Hasselblad X2D with the wonderful advantage of not having to buy any new lenses. This could create a new category and sell well to both current Z body users as well as attract people away from Canon and Sony. Of course, my idea is far too late. Nikon has already made its choices and created prototypes which must be out in the wild undergoing "real world" testing right now. The odds must be over 95% that it has a standard 36 x 24 mm size sensor with the only question being how many megapixels on it and what level of image quality they are able to obtain from that sensor.
