How do I make an old vintage flash with only one contact on hot shoe synchronize and fire when using Pentax DSLR (K-30)?
I know it works, because it charges and I can fire it manually with release button, and I know the contact works, because the old no-name Sony film camera I found it on can trigger the flash when pressing shutter.
It also seems to be stuck in 90° and I have no idea how to rotate it down, should it just rotate with light force?
Something in there might be broken and stuck, if there's no special way to rotate it.
Pic related is more or less what it looks like.
