Operating on the Graphex 135mm lens tonight. Anything below 1/25 doesn’t work, B does but not T, flash trigger also dead. I already cleaned up the shutter blades with no luck. Finally cracked open the shell and looked at the inside. A simple drops of oil in the right places and a good cleaning of the contacts solved both issues! The lens is super snappy and I am very happy!
