On the left is my Nikon D200, 35-70mm Nikkor and battery grip. This was my main camera from 2006 to 2014 and is still the camera I used the most and for the longest.
On the right is my Nikon D2x with Sigma 10-20mm. My late father-in-law bought this used camera for me around 2016 as a thank you for reviving his very sick laptop and saving the data on it.
In the centre is my Olympus OM-D E-M1 ii with 12-40mm Pro lens which is my current main camera. As I get older, I increasingly value small size & light weight in my camera gear!
