I have been fighting arthritis in my hands so using and carrying 9 pounds of camera and lens has become very difficult to do (Nikon D750 with Sigma 150-600 Sport). My current rig gives wonderful results. I use it handheld and hate using a tripod. I have been researching and I'm thinking about changing to an Olympus OMD EM1 ii with a Panasonic 100-400. Nobody in the area I live handles these and I'm very leary of ordering online without having handled the camera before. This combination would only weigh about 3 pounds which would be a lot better for my hands. Has anybody out there used this combo? I would like to hear some feedback and see some photos. Any other suggestions would also be welcome I shoot a lot of wildlife and most of the time I am walking around a lot.
