I started off using the Olympus 4/3rds system about 10 years ago, but have now moved on to Canon camera gear.
I currently use a Canon 6D with a EF24-105L lens for my landscape photography plus a Manfrotto tripod.
For my wildlife photography I use a Canon 70D with Sigma 150-600mm or Canon EF 70-300mm lens plus a Manfrotto monopod.
I also occasionally use a Sigma 105 F2.8 macro lens.
I use a combination of Adobe Photoshop CC, Aurora HDR 2019, Nik Software, and Piccure Plus for processing my images.
