Thanks Colin, yes I am certainly impressed by the resolution performance of the 300PF. I sort of predicted that for myself when the first MTF charts were made public, in the center 5mm radius both the 10 and 30 lines/mm are really squeezed together at the top of the chart, which benefit both small sensors and TCs.
I know of a certain forum member who has an AW1 etc. and might still have a 600/4 for evaluation...
... if atmospheric conditions cooperate....

That said these straightforward moon closeups are more of a technical task than a creative endeavor. And as a test subject it cannot show how bad a lens is, only how good it at least can be under the given atmospheric conditions. It is fun anyway.

Jan Anne, I like the "cave" image, looks cozy in there.
Elsa, it should be the same possibilities for creativity and variability on the moon as in a barren desert here on earth, given a little mobility. Thinks about all the different rocks.

It is just when capturing the moon here from earth that we all have essentially the same perspective and viewpoint, except for a little wobble of the moon, and the variation in lighting.
