I want to brag about how how amazing the Godox lights are. They are branded under the names of Cheetah light, Newer, Adorama Flashpoint and several other manufactures. In theory, they are everything I could ask for in a portable lighting system: they are light weight, powerful and user friendly. I chose to order from cheetah light as opposed to ordering from amazon or other online vendors. Edward Tang, the owner will give you a 1 year warranty and has the fastest customer service in this business should anything fail he also has employed a full time technician to specifically repair all of his lights. The cheetah light v850 kit includes a lithium battery, charger, usb receiver and a hotshoe transmitter.
I have tested this flash on the A6000, A7r and A7s and it simply will work on all three without fail. I am trying to get an video up to show you the recycle times on the A6000, incredible is the word I’ll use to describe!!
This is probably one of the cheapest solid solutions that you will find for the A7, A7II, A7r,s, and the A6000. The v850 paired with the cheetah light 180 and 360 is more power than you will probably ever use. The TX will operate and fire each light and you can set groups.
