Will it work with a Canon M50 and Canon 470EX AI speedlite?
Asked by: ankit
The 470 AI does not have a receiver built in. You would need both a transmitter and receiver like this kit https://bhpho.to/2Zsmexp.

A known defect of the original version was battery rapid drain even when switched off. Has that issue been fixed in this newer release? I'll upgrade if I can quit removing the batteries every day.

Can you turn off the AF focus assist beam or does it always go on in low light conditions?
Asked by: Scott
The AF assist beam can be turned on/off in the transmitter settings. The flash AF assist beam can also be turned on/off in the YN600EX-RT II flash settings. On my G15, neither AF assist beam does anything regardless of the settings. I don't know how bright these would be since they are behind a dark red lens. The G15's AF assist beam works and is very bright white. Turning the G15's AF assist beam on/off has no effect on the transmitter or flash AF assist beams. Overall, the transmitter/flash work very well on the G15, but it's always a roll of the dice with 3rd party units. It may behave differently on other Canon cameras. Interestingly, this transmitter/flash combo works great on my Nikon D850 in manual mode even though the hot shoes are very different. No adapters required, just pop the transmitter on and shoot.

Assuming all firmware is up to date, it should certainly work on the 5D series cameras.
