I took a walk yesterday with only the G7X II in my pocket. I saw a Heron in Plum Creek and decided to see what it would look like if I tried to make a picture at maximum zoom. As wider or closer scenes go, the G7X II is acceptable for a lightweight system but I won’t be using it for wildlife.
In the past I had longer focal length zoom lenses on DSLR cameras, and I did photograph wildlife, but the amount of wildlife has declined quite a bit and I have gotten tired of carrying heavier gear. If we had more wildlife around and I thought I would feel like carrying it around, I could walk with the Fujifilm 55 – 200mm lens on my X-T2 in good weather.
