I have only shot with mirrorless digital cameras. I bought my first high quality digital camera, a Lumix GH-2, which I still use, in 2011.
It’s taken a decade for others to catch up! Heh – I’m usually at the tail end – or past the tail end of product adoption but in this case, I was ahead of time 🙂
