Today I got a delivery of the latest Nikon super telephoto lens, the immense 200-500mm f5.6E. So far my main comment is that it’s a beast to hold but I can see the new possibilities for my photography career, airshows and birding will be a lot more interesting.
One interesting note is that with the TC20E-III I was still able to get autofocus to work even though it’s not meant to work beyond f8.
Here’s some unboxing pics, hopefully I’ll get some decent daylight in the next few days for some decent samples.

I was tired so dug out the monopod for some late evening shots (TC20-III attached)
I started keeping a short “next three tasks” list instead of a massive to-do list, and it’s made it much easier to actually begin work. The point about reducing friction really resonated with me—sometimes productivity is less about motivation and more about making the first step obvious.
