Nissin i40 and i60a fit problem.
Hi I have both the above flashguns, one for my wife FZ200 and one for my FZ1000.
Great flashes but, they are both a nightmare to get on or off either camera. So I tried filing the upper plate surface of the i40 , it made a slight difference. But I suspect that the real problem is the locking pin which doesn't seem to retract enough on either flash. I'm thinking of filing that down, as anyone found a decent solution. Thanks
