I just realised that I took tons of photos during the party. I used combination of three cameras, the main one being the Sony Alpha 7R mk II with the Zeiss 24-70 lens with a flash. The other two were the wide angle Leica Q and the X-pro 1 coupled with the 35mm f1.4.
The combination worked a treat and as I only had the flash for a couple of days, it worked much better than expected. I would be employing the setup for the upcoming MSH meeting in late April as I would be tasked with taking the photos again.
