Spectacular picture! Can you add your gear to your profile? I am interested to see what lenses you used on your trip
Canon 5D4 plus 300 2.8 ii. And guide's 5 flash setup at low power with remote trigger. Yong nuo I believe. I have a similar 2 flash setup now.
I brought my 100-400 but it dropped and broke on the second day so I didn't get much use out of it on that trip. I have it back now repaired by the way.
