Hi,
I have tried searching for this, but was unable to find anything related to this issue.
I recently purchased a Super Angulon 90mm f8 from eBay. I put it on a Tachihara and as I was trying to focus, I noticed that the Tachihara bellows rails' reflection also showed up in the image even though it is outside of the coverage area. I moved the lens to the front moving the back plate forward to as far out as I could move. The front element is just a little behind the front end of the bellows rail and not visible in the image to the naked eye. However, to test it, I rubbed my hand over the front rail and I could see my hand in the image on the ground plate.
Does anyone know if this is normal? It seems weird to me that it is picking up reflections from outside of its image area. Any ideas on how can this be corrected?
Thanks.
