But regarding segmentation of basic features, take Nikon's current mirrorless range:
-Z30 (20mp APSC): tilt and swivel LCD, no viewfiner, no in-body image stabilization (IBIS, which all midrange and higher end phones have), neglected set of APSC lenses, single memory card slot, no flash
-Z50 (20mp APSC): no IBIS, neglected set of APSC lenses, single memory card slot, has flash, one-way tilting LCD
-Z5 (24mp FF): 2 card slots, has IBIS, no flash, slower continuous burst rate than the Z30 and Z50, one way tilting-LCD
-Z6 series (FF, 24mp, for all 3 of them): Z5 with faster AF, higher burst rate, slightly better sensor and better video, still no flash, more expensive
-Z7 series (FF, 45MP, 2models): A D850 with IBIS and better video and slightly worse AF, still no flash, one way tilting-LCDm, costs more
-Z8 (FF, 45MP): a cut down Z9 or a sped-up Z7, has IBIS, no flash, better AF, higher burst rate, very expensive
-Z9 (FF, 45MP): a flagship with a battery grip but no flash, still a non-video optimized LCD, astronomically expensive
The Z6 series has the best video specs (for the price, the Z8 and Z9 are too crazy to consider) but doesn't have a a flippy screen, the Z30 is aimed at content creators but doesn't have IBIS or an EVF in case they want to use it for non-vlogging purposes even though the sensor is good for it, the Z7 would have been an ultimate stills camera but it doesn't have a flash, the Z50 and 30 still use the old but good 20mp sensor from the D500 which was announced in 2016 and have limited set of small lenses that take advantage of their smaller sensor.
-I don't even know the differences between the Sony a6000 series cameras; they're supposed to have good specs and processing power yet Sony also has a dedicated vlog line with the same APSC sensors, and only one of them have IBIS
-All of Canon's APSC lenses are slow as fuck yet don't reflect that in their cost
-Canon, Nikon, Fujifilm and Sony gimp their lower-end products by not giving them enough buttons / dials / direct physical controls
