Thanks for the reply. I realize that some of my questions were poorly expressed.
1. The Blad CF lenses have an internal shutter. If that is closed, how does light get into the camera body? By inference, how do you open it.
2. The lenses have a curved rocker on the side to stop down the lens, does this have to be used to stop down the lens?
3. Do any settings on the lens have to be set? In what mode(s)?
4. If I want to use an incident light meter in what mode would I make the settings. Will those be on the lens or on the body?
5. Is it better to shoot in A or S mode? Why?
6. What parts of the exposure components-f, time-does ISO adjustment effect. Does it only change the shutter speed? If so how does the aperture get either adjusted or set?
7. You mentioned something about ExpComp----what does that influence in this scenario.
1. Sorry, the 'blad lens I have is a C lens, no shutter I think so I can't help in some of your lens specific questions. Bronica lenses I've used that have shutters remain normally open so I just ignore them and use the camera focal plane shutter. If the CF shutter is normally closed I don't know how to open it. It's usually up to the maker of the adapter to add a key on the lens mount side to interlock with the lens to open the shutter.
5. As I mentioned above I use A mode so that I can set my focus and exposure WO or close to WO, focus, close down the aperture (If I want to) and let the camera manage the shutter speed. Many people use M mode though and I do occasionally.
6. ISO increase in effect just makes the sensor more sensitive (by amplification), for example if you increase the ISO from 100 to 400 you gain 2 stops. You can use this to close down the aperture by 2 stops to get better DOF, or decrease the shutter speed by 4x to hand hold or freeze motion better, or split it for a combination. In manual lenses the aperture is changed by the aperture ring as the camera cannot interface with it (or know the value, it just knows there is more or less llight coming in as the aperture is changed).
7. On the A7 series cameras there's an exposure comp wheel that allows you to adjust exposure by up to + or - 3 stops. So if you want to increase the exposure by 1 stop, just set it to +1 (or 1 higher than where it is). If you're in A mode then the shutter speed will drop in 1/2 to allow more light in. If you want/need to keep the shutter speed where it is then you'd have to open the aperture by a stop to maintain the same shutter speed.
