Cameras which are seeing rising prices are not the legendary professional workhorses. Hassselblads, Pentax 67s, Nikon F4/5/6 are reasonable. Even the Rollei 3.5 which was the legendary professional machine is still reasonable. Itīs the 2.8 F that is coveted.
Itīs the camera jewellry like Contax T3, Leica M6 (Leica had long been out of the pro game when the M6 was released. M6 and M7 are enthusiasts cameras), Zeiss Ikon that is seeing a lot of hype.
Otoh, compared to Leica lenses everything looks cheap.
