They are interchangeable.
The 75's have a nice bayonet hood, which they share with the 60mm; the others from 40 to 250, except the 105 1:1 Macro, slip on and then snap into the holes on the outside near the front.
The 40 and 50 share a hood. The zooms and the 500's have their own hoods.
The 105 1:1 Macro has its own bayonet hood, but I haven't been able to find one.
There's also the bellows hood, which will fit everything from 40 to 250, using a 62mm adapter ring that mounts on the front threads. The original 75mm uses a 58mm ring, and the 105mm 1:1 macro needs a 67mm adapter ring. The hood uses an insert in its front filter slot with the longer lenses to reduce the opening size. The bellows hood is not as easy to use, but when you need maximum protection against stray light, it works best. As the longer lenses use a round hood, and it covers several focal lengths, the bellows hood is very useful there, if you don't mind the extra hassle.
The snap on hoods are fine for most things. I use the bellows hood most when I'm using a tripod, as those are times I most need it anyway, like late afternoon and night under overhead illumination.
It has filter slots front and rear.
I have found KEH to cost the same or less compared to ebay for used hoods, including the bellows hood, and of course you know what you're getting that way. Ebay has a lot of new hoods, but they're usually stupid expensive. I got extra adapter rings and inserts there also. Bronica made smaller adapter rings, like 49, 52, and 55mm. Bronica says the hood can be used with 135 format equipment, so I guess that's the reason for the smaller sizes.
