About Timothy Mayo

I love shooting wildlife the most but will happily point my camera at pretty much anything. I started RFShooters.com with my amazing sister Emma to share our own adventure with the Canon R Series. At present I own the R5 + RF 100-500 lens. I also run a similar site for Sony Alpha Shooters and also shoot with a Sony A1. I find new camera technology fascinating so I unfortunately suffer from a very bad case of GAS! You can follow me on Instagram if you wish! Although I don’t post as often as I should.
