The price of the R8 is quite underwhelming. You can buy an RP for 899 Euros. The R8 costs 1799 Euros...
It is always easy to compare the actual street price of an old camera with the MRSP of a just introduced new camera.
But it is comparing apples to oranges.
Of course, you will also see some rise when you compare both MRSPs at release date. But
- RP has an old, reused sensor
- RP has the weakest AF system of all FF R cams
- RP EVF is so slow
- R8 gets the latest sensor, an up-to-date EVF and the latest AF system
- R8 is almost an R6 II at a fraction of its price
- and globally since the two releases there is all that inflation from COVID, war, etc.
Still, and of course with reason one can argue, that that price is too high.
But nobody is forced to buy Canon, that camera and at release price.
