I started as a Canon user and I also owned Panasonic GH4 while slowly doing the transition to Sony starting with the A7SII. I have a large inventory of equipment from led light panels, reflectors, flash triggers, a 360 turntable, backdrops, stands, stabilizers, various lenses, sliders, external monitors, tripods etc.
Most of my cameras record in 4K. I use Adobe Creative Suite to edit my videos and photos (Premier Pro, After Effect, Lightroom, Photoshop). Every shoot is different and sometimes it’s necessary to purchase additional props.
