Camera Systems

I am currently using 2 systems for wild life photography. For heavy duty requirements, i am using Canon 7DM2 Body, and pair with Sigma 150-600mm (Sports). For lighter and walkaround shooting, I will use Panasonic GH4 and pair with 100-300mm.
I own multiple bodies and lens for various purposes now and in the past, for backups and different kind of shooting requirements such as wide angle or Macro.
