What shutter speed were you using. If it was a slow one then, yes, that could be the problem. On CF lenses the slow shutter speeds have an indicator as a reminder. Not sure about the c lenses but the situation is the same.
Have you fired the camera with the back off to observe the behavior of the “barn door” shutter in the body to ensure that they are operating correct?
That’s what it looks like to me. At fast shutter speed there’s not likely other sources of such an obstruction... unless there’s an errant piece of paper inside the camera or film back.It looks like the bottom half of the barn doors are not open
I'd agree, although I expect that it is the top half that is misbehaving - images end up inverted at the film plane.It looks like the bottom half of the barn doors are not open
Yeah take off the back and lens, fire the shutter, and look at the barn doors. They should be open until you release the shutter.Both barns are not fully open when the lens shutter is released. The top barn opens slower/later due to the mirror, and the overlap with the bottom barn.
Could be out of sync, or a slow barns door mechanism.
Do both barn doors fully open at longer shutter speeds? if not, you probably need a new rubber brake wheel.
I see this problem on occasion in the shop. It can be the auxiliary shutters are not opening and closing properly. Usually due to a bad main spring. The brake mechanism could be faulty too. However, to me it doesn’t look like a barn door issue at all. It could be sequence issue. I think the lens is timed improperly. To check, remove the lens and back and determine if the auxiliary shutter is opening and closing correctly. No hang ups or slow closing. If it is working well then it is your lens. If the bridge needs adjusting or repair, then the shutter may be opening later than it should be causing it to open when the auxiliary shutter is actually closing. Next roll, put the shutter button to “T” and then the auxiliary shutter will stay open throughout the whole cycle until you return it to “O” and the doors close. If the blocking of the image goes away then I’d say time for a service of your lens. If the auxiliary shutter is obviously wonky then get the body serviced. I would actually just get the body and lens to someone qualified and have them both inspected. It could be the “relationship” between the body and lens as well.All of a sudden my Hasselblad is acting very strange. All of a sudden it exposes only half the negative with light. It looks that the picture is taken when I RELEASE the button, and not when I push it. Something must have happened with this lens. My local camera repair guy doesn't know what it is. Any idea? (please tell me if there is another forum that might be more appropriate)
