I have been looking for an upgrade from my Canon SX50 for a long time. The SX70 reviews do not look good. (Unless anyone knows differently.) I want 4K and a bit more zoom. 83x optical on the Nikon P900 is about right I think. But it doesn't have 4K. I was wondering what the P1000 would be like used at half its zoom capacity. All the reviews seem to want to touch the moon. I've not seen any half zoom reviews. At full zoom wobblies seem to creep in on what I've seen online. Can anyone comment how the P1000 performs at half zoom as I want to keep the videos pretty solid.
