I had a request to confirm shutter fires ( it still does ) and to check on how clean lens was. To do this I had to put shutter on B setting and look through rear of camera. However its a very small lens and I really cannot say for certain how clean it is. I just need to verify this for all bidders. I also need to mention that the catch to hold bellows in is very light and now its not holding front plate in and the spring seems to be stronger than the catch. I do not want to make my own adjustments and would rather inform all bidders. If you wish to withdraw your bid because of this, please do so. regards Tony
