Today I got back the first flash HVLF60M with firmware 1.10
Side by side Version 1.10 vs Version 1.00
No overheating even at 80 flashes vs 22~25
What I have notice with recharging time in sec, as the number of flashes increase (over 20 flashes) the delay for the ready lamp increase. It needs almost 7~8 sec when it reach the 70~80 flashes.
The version 1.00 it seems to recharge the same time even when it reach the point of overheating.
Next week I will send also the second one ... and remember no charge is free from Sony
