I took this shot yesterday at dawn (technically: before sunrise), on a really clear and cold morning, from my homeplace patio. The foreground trees cover a hillcrest maybe 2 miles away, and the mountain peaks in the background are 70 miles (as the bird flies) away. The center peak is "Sustenhorn", 3504 m above sea level. I live at 520 m. PeakFinder view for your reference.
Being a technically oriented guy, I wanted to explore the limits of my gear (A9 and 100-400 GM) at maximum zoom level. Shot taken from a tripod, with wireless triggering. Focus and light setting on "Auto". I did some medium sharpening in Capture One Pro. On a scale from -100 to +100 I chose + 50.
This is not about artistic merit, composition and such. Just the "raw" performance. Please comment honestly - I can take it. 8-)
