Does the Nissin flashes overheat easily? I have the Sony 43M and used the 60M and both have overheated on me at unfortunate moments...
Totally agree... the 60AM has overheated on me on two occasions... and it takes quite a while to cool down. It lasts longer if you're shooting at less than 1/4 power... it shuts down very quickly on continuous firing at 1/1 power.
