seeing many complaints on local FB boards from experienced wedding photographers about the Sony A711
Glad I went 5D4
---------------
Be Advised- They dont seem to work too well with Flash systems
Seen this complaint many times on the Godox boards
Owner
"""I am wedding photographer and i use Sony A7 III and Godox Xpro S trigger with Godox V350S, Godox V860II, AD 200, AD 600. I have problems with them 15-20% miss fire
I tested today all and Xpro S and Godox V350S use as trigger miss fire 20%. Godox V350S only using with body same miss fire and heating quick
If i put Godox V860 II as trigger is ok at 1/250, i have 0 missfire. But in HSS i have 90% miss fire
If i set EFCS (E-Front Curtain Shut.) from my Sony A7 III to off is ok, 0 missfire but is very loud. If i take a picture, sound is very loud like i shoot 3-4 picture.
( And AF lamp for Godox not working. I write mail to Godox but 0 response. Any solutions?"""""
response from an expert in the industry who uses Sony. Truly a gifted guy who knows what he is doing
"""* Turn of EFCS when using flash. It’s that or get inconsistent firing AND banding.
* Turn off red eye reduction.
* Use alkaline batteries in your XPro.
* If you are using HSS you may be hitting the thermal protection limit. Lower power and raise ISO, slow down, or turn off and turn on the OCF to reset the protection counter.
* Try a different channel as you may be getting interference.
* Check firmware and update if necessary.
I shoot with the a7rIII and a7rII with every Godox flash and have zero issues with misfires.""""
or this one
"""The Sony uses a phase detection focusing system so it operates differently than most other cameras, especially Canon/Nikon dslrs. I also believe the focus assist will not work with EFCS."""""
or this one
""In my opinion Is the xpro transmitter. Try with X1. I have a lot of issues with sony version , but same happen with Canon version of XPro, replaced by X 1, no problem"""
I decided to stay Canon and got the 5D4 over the Sony. For these reasons and many many others.
Try before you buy and be advised----Its another totally different camera system to learn and conquer
