Lucky for you, lucky for us :)

I also have no idea what any of those lens details mean but thank you for the detailed response. I didn't know a lens could have anti shake, does that work similarly to a smartphone sensor's optical image stabilization? I guess you could compensate for movement with the final destination of the light or the path it travels through. I had never thought about it on a bigger camera, but when the sensor is scaled up that large, it would have to be easier to adjust through the lens than to move that entire sensor quickly.

Man the D500 is such a beast for wildlife photography. I wish they have an equivalent for the Z series.
