Ok so I went and looked at the camera. It's in near mint condition, there isn't a single scratch on it. So here is what he has. He has a lot of accessories which I'm not too familiar with, so if anyone here can help me that would be great.
RB67 Pro-S Body with Waist level VF and 120 manual back
90mm f/3.5 Lens (non "c")
140mm f/4.5 Macro C
3 different grips for the camera. Two of them have a mount for a flash.
Two M-adapters, one vertical and one horizontal (I have no idea what these are, can anyone clarify?)
A case for the camera and boxes for the lenses.
Basically everything is in perfect near mint condition except for maybe the back. He told me the foam light seal had deteriorated and he scraped it off. This might need to be repaired or I might have to just get a new back.
I don't know why he had three grips. All three serve seemingly the same function. One is just a grip, and two have a shoe for a flash. One of the ones with the shoe also has a cable that comes off of the grip which seems like you need to attach somewhere. Also there are two "M-Adapters" I have no idea what these are for. As you can tell I'm not familiar with the accessories at all so if anyone can enlighten me on what some of these are for.
Is the 140mm macro lens a good lens? I'm sure it is but I just wanted to verify.
Finally, what do you think all of these would go for? We didn't really talk about price, he wanted me to go and think about it etc.
