I was trying out the Summilux-R 80/1.4, that arrived today, on the A7r2 when cranes were overhead.
These images are a 3280x3280 crop from the original size of 7952x5304, then reduced to 1988x1988.
Here they come.
Beginning to circle in a thermal to gain height.
After having gained height, ready to move onto the next leg of their migration route.
Sony A7r2 + Leica Summilux-R 80/1.4, processed in C1, followed by Auto Contrast in CS6 to make the cranes better visible in the images.
Unfortunately that also overexposes a few spots in the images. Oh well. The .ARW files themselves were not overexposed.
Here is an un-cropped, un-auto-contrasted, only-reduced-in-size version of the middle image above.
Obviously using an APO-Telyt-R 180/3.4 would have better filled out the frame with the Sandhill cranes.
