We have been in Photography and Filming since early '30ies.. During those years the very refined material was German, camera bodies and lenses, Rollei, Leica, Linhof, Zeiss and the kind..
Let's do some considerations about pricing..
For a young Photographer willing to start his career or a Professional who wants update his camera set will be needed 2 bodies, 2 flashes, 2 Battery Packs and I would say 3 or 4 lenses NOT including the very costly superzoom f.2,8 or f.4. Therefore we have (assuming USD almost same of EURO)
2 bodies at 4.500 each = 9.000
2 flashes at 500 each = 1.000
2 Battery Packs 300 each = 600
3 L Lenses at average 2.000 each = 6.000
Total around 17.000
