I’ve recently updated my main camera to a Canon 5D Mk IV - mainly because of it’s better dynamic range and low light performance, although the snappier focussing and a host of other improvements were attractive too.

I decided to carry out a few tests to see if the Wifi performance was any better or worse than the 6D. The short answer is that it seems about the same. So no surprises there.

I thought it might be worth recording some results though.
