If you want a flash that will not get overheat nor shutdown quickly then stay away from the
Sony HVL-F60M flash. The Sony HVL-F58AM is a little better but no ATG ADI TTL.
Just like the Canon 600EX-RT and Nikon SB-910, we demand weather sealed.
So the heat from the flashtube & components can not be cool down due to those seals.
You have some choices, but one is clearly the best.
But some think it is not available.
1. ATG Gold MG8k Flash Kim X3
2. ATG Gold Trio Flash Kim X3
3. Metz 76MZ-5
4. Quantum Qflash Trio
5. Quantum Qflash T2 and T5d
6. Metz 60CT-4
7. ATG Gold Metz 60CT-1 & 2, Metz 60CT-1 or 2
8. ATG Gold Pro II Flash Kim X3
9. Profoto B1 (500ws). Must get the radio transmitter
10. ATG Gold Profoto A1 (800ws). Comes with ATG R Transimtter.
From 1 to 7, these flashes can fire all day without overheating nor shutdown.
#1 can shoot & recycle under ONE SECOND.
#1 and 8 can do nine wireless flash modes.
#1 and 8 can do 1st, 2nd and HSS/Auto FP/HSS
#2, 4, 5, 6 and 7 require special external battery packs.
#3 required special hotshoe adpater for TTL.
#8 is a direct fit on Sony latest hotshoe.
#9 is only for Canon or manual shooting.
#10 has awesome power of 800ws in radio ETTL II, ITTL and ATG ADI TTL.
If you are a serious into shooting events & weddings then an external battery pack is a must.
Pushing that ASA/ISO high is not the answer.
When was the last time you see well known indoor portrait photographers shoot without monolight and can sell one image for over $6,000.00?
Quantum Instruments make & was the king of battery packs until ATG Elite Gold Battery Packs.
ATG Elite Gold Battery Packs
Quantum Turbo Battery Packs
Both of these required HV cable designed for your flash.
HV cables for ATG, Canon, Nikon, Metz and Sony
Again, if you need the power and using Canon or want to do it wireless radio manual flashes, then go for the Profoto B1. This set will hit you under $3,000.00.
More power, then #10 is it for shooting with Sony, Canon or Nikon.
Shooting wireless radio ATG ADI TTL (Sony), ETTL II (Canon) or ITTL (Nikon).
This can do what the Profoto B1 can not do, wireless radio in 1st, 2nd and HSS.
If you can't afford Profoto nor play with the big boys, don't ask for the prices.
The biggest drawbacks for the working Sony professional photographers using HVL-F60M Flash:
1. HSS is disabled once flash is bounced
2. Overheat & shutdown very quickly
3. Fresnel Lens will warps or bubbles
4. No PC Sync Socket
5. No ATG Auto Sensor
6. Can not get wireless IR flash (Remote) once flash is pointed into a softbox
7. Weak Hotshoe Locking Button
8. Lousy instruction manual
9. 160 of sync on wireless flash
10. Delayed flash due to Shutter Assy has to close & up that ATG and Gary Friedman knew in R/D.
Bet you didn't know that the Sony HVL-F60M Flash is the most expensive flash ever came and made in China?
