And a quick few seconds of a fucus pull thru a palmtree, with Sigma 600mm plus tamron 2x, Kenko 1.5x and Pentax 1.7 stacked.

The moon looks brilliant. My teacher told me the sunny 16 rule works really well for the moon. However, I don't actually know how to apply it, especially without manual control over exposure. This video also underscores the unfortunate need for a follow-focus when doing a focus pull on a long lens.
