I mean the people that want a small and cheap ‘real camera’ are not the same people that want a reach limit busting 7D replacement.
The first group have the M system. It is small and comparatively cheap, it has the lenses most users will actually use on it too. It is very feature rich with excellent AF and fps.
The people that are after a 7D replacement because of the reach limit argument have the RF800. They used to use a 7D II and a 100-400 4.5-5.6 II, so 20mp at an effective 160-640 focal length, with an effective f5.6-8 dof. With an R5 and RF800 they get 45mp with an 800mm lens at f11 dof. So one stop less dof. As for the light gathering argument, the ff sensor is over twice the area of the APS-C sensor so gains over a stop of iso performance and the R5 is considerably better than a stop of iso performance better anyway!
The 7D II cost $1,799 and the 100-400II $2,399, total $4,198. An R5 costs $3,899 the RF800 $899, total $4,798. Thats $600 more six years later with longer reach, more than twice the mp and fps, and MUCH better AF, all things reach limited shooters say they want. Downside is one stop of dof.
So why don’t those mythical R7 supposed buyers put their brains in gear and realize they already have it!
