I'm an amateur photographer based in the UK, I use two main camera systems - a Nikon D850 full frame and an OM System OM1 Mk2 micro four thirds, the difference between the two cameras is stark. I also have an Olympus EM10 as a street/pocket setup and occasionally some film work courtesy of my Nikon F4.

The micro four thirds platform gives me a compact easy carry option and is a computational beast, it has IBIS, built in ND filters together with an adjustable GND, live composite mode, focus stacking which generates the finished single image in camera. The full frame Nikon is brilliant, amazing metering and auto focus, but, it's heavy and bulky for carrying around especially having lower back problems. I will continue to use both as the subjects and opportunities allow.
