I've recently made a significant change to the equipment I'm using. If you follow my work you'll know I've been shooting with Nikon D810/D850's and Sigma Art lenses for the last few years, but as someone who travels a lot shooting stills and video for GONE SHOOTIN I'm continuously struggling with both the size and weight of my kit bag. When you add on battery packs, batteries, filters, and accessories it all becomes just a bit too bulky at times.
However, I've also been shooting Sony equipment in parallel for a while to ascertain whether it was good enough to transition to fully. After using a couple of A7RIII's and an A9 for a year and being delighted with their performance and reliability, I've now decided to retire the Nikon and Sigma kit and transition to shooting Sony Mirrorless Cameras exclusively. I particularly love Sony's incredible Eye Auto Focus feature when shooting portraits, there's just nothing else I've shot with that compares to it. I've also found that the Sony lenses perform as well, and in most cases better than the equivalent Sigma Art lenses that I was using previously but in a lighter package. Having the assignable focus hold button on the Sony lenses that let's you assign eye AF is a brilliant feature, and the one killer feature that I missed most when using the Sigma's.
I use the equipment below currently because I feel it offers the best solution to my particular professional requirements.
