I received the ShenHao TZ45-IIB a few days ago, it is well made and has great movements on it. How ever I have had two little things to pick on, first of all the ground glass is rather dim, so best to make sure you have a fast lens on the camera. Second of all is because I have a 90mm lens attached to the camera it has not got as much front rise as I’d of hoped. So this is my reason for bag bellows, a lot more freedom in the movements of the camera. I could have gone for a recessed lens board but I felt I should make sure that the movements are going to be available and went for the bag bellows.
Having some film developed from a shoot in Liverpool so I shall update with them when I have received and scanned them.
