For a few years, I've been a Tour Photographer/Music Photographer, working with artists like Anthony Hamilton, Common, Janelle Monae, Lecrae, and Kem, to name a few.
I recently finished an 8 week long tour with Anthony Hamilton & Fantasia, documenting Anthony's tour life. The captures included video (90%) and photos (10%). For this tour, I only used one camera body, a Sony a7r II (mirrorless), and two lenses, a Sony 35mm f/1.4 Zeiss and a Sony 55mm f/1.8 Zeiss.
The immediate discovery is the obvious difference in weight, and the size of the camera bag needed. I went from carrying a very large Lowepro ProRunner 350 AW backpack, to a rather small one, Lowepro Format BP 150. I did however miss out on the 70-200mm focal length, in certain situations. But, not so much that I'd carry that bulky lens for 8 weeks.
A second discovery, was the ease of use, when shooting run & gun video with artists. The Canon 5D's lack of tracking/auto-focus for video, used to hurt me a lot. I haven't mastered manually focusing video yet. So, the Sony does that work for me.
At a point in the tour, I picked up my Canon 70-200 f/12.8, from home, and my CommLite Lens Adapter, to use on the Sony body. It worked quite well for me. Not a perfect setup, but it got the job done for sure. I have yet to figure out why Sony 70-200mm f/2.8 lens is almost $3,000, so I will have to settle for the adapted Canon lens, when needed.
