Lawrence-
Welcome to APUG! I'll put in another vote for Hasselblad, since the system has been around forever, there are TONS of accessories for it, and with few exceptions, everything is backwards and forwards compatible. The camera itself is lightweight, very comfortable to hand-hold (I can get acceptably sharp exposures hand-holding to 1/15th of a second with mine), has a range of lenses from 38mm super-wide and 30mm fisheye to 500mm telephoto, and there is a zoom for the Hasselblads too- a 140-280 F5.6 zoom. Big beast of a lens though. The biggest determinant of if you like a Hasselblad or not though is the square format. If you like shooting squares, you will LOVE the Hassy. If you prefer rectangles, then an RB or RZ would be the better choice. If you go down the Hasselblad route, avoid the older chrome C lenses and the 500 C bodies, as they are now 35+ years old, and repair parts for the C lenses are harder to come by, and the C bodies are also at the end of the factory parts supply line. The black C lenses are ok, as they are generally newer, and so in better condition, but keep them in line for focal lengths you won't shoot as much, like a 250 or 350. Stick to 500 CM bodies and CF lenses and you can put together a very nice kit for reasonable money. Watch out for any camera that was used professionally by a previous owner. Especially if the seller mentions the words "Wedding Photographer" in conjunction with the camera in the same sentence. Run as far away from that example as you can, as fast as you can.
