These are full frame. Sorry for the earlier error. Comments?

Non-IQ comments (as I have negligible experience with using "tilted near-infinity horizons" (TNIH) for "good copy vs bad copy testing" (GCVBCT):

Lotsa questions. I'll just deal with one for now, and circle back in the morning.

  • How far away would you estimate the tree line is at the horizon? Half mile? Full mile? Less? More? Ever actually stepped it off, if that would be feasible?

I estimate the tree line at between 500 and 800 meters. Using the formula in this post:

(I can't believe there have been no comments on that), (35/55)^2 = 0.4, so I should be OK with anything beyond about 200m, even with a much sharper lens that's just as sharp at the edges as at the center.

The hillside you're looking at is very steep, and thickly wooded. I couldn't possible climb it. The vertical rise to the ridge is about 700 feet from my yard at the low point.
