What's causing this vignette on 6x8?
I recently obtained an RB67 Pro-Sd, as well as an 6x8 motorised back and the K/L macro 140mm f/4.5. Shot a test roll and noticed what appears to be vignetting in the corners of one side of the negative. The bellows were fully extended for this shot, to maximise the image circle.
I thought the Pro-SD worked with 6x8 backs by default (i.e., no need to upgrade baffles or anything). Anyone have an idea as to what could cause this vignette?
