Will share my results here. Used it for backyard wildlife and a trip to a nearby National Wildlife Refuge.
While I still needed to crop, the images with this lens are much larger then from the 80-400VR lens I own. The birds like the trees on the edge of my lawn. I was photographing from an open window in my house which is the perfect blind.
