I have been shooting with my a7II since 2017. It has been used in the mountains, caves, rivers and all images have been of really good quality. I have been able to shoot handheld in the caves in Arkansas I was impressed with the photos. The camera is light and with the addition of the battery grip fits my hands comfortably. Even with my Sony 70/200 f4 lense you can shot off hand without a problem. With it being a full frame body, I can get the photos that I want in the size I want. In Cades Cove outside of Gatlinburg, TN, I was able to catch very good shots of a Black Bear juvenile running in front of our Jeep. This opportunity came at a seconds notice from my wife and our friend in the back seat shouting "Bear, Bear:, so I had to grab my camera, lean out the window and shoot about 5 frames of this juvenile.
