A reader sent a few pictures of his custom Leica Visoflex (Typ 020) mod with an additional flash sync plug that allows you to use studio flash at the same time with the EVF. If there is enough interest maybe Leica or a third-party manufacturer can create such an adapter and make it available for sale. This specific prototype was built by a Swedish Leica fan. The mod is actually just a sync plug connected to the ground of the housing and with an additional pin drilled (right picture see white pointer) to the X-contact. What do you guys think?
Additional information: mod | drill template.
Thanks Joakim Larssen and Christoph Protz for the pictures and details.
