Conking

I had the opportunity to go to the stadium of light on saturday 22/10/2016 to attend the Conking something totally out of my comfort zone 
My flash gun didn't appear to be talking to my camera and my lens 24-70mm did not appear to be working on one of my bodies I did have another spare body with me so use that but still my flash gun wasn't working here is one of the images I managed to take more to follow
