The barrel distortion is even more noticeable in this shot. If the horizon was really that curved the Earth would only be about 30 miles in diameter.
While the overall exposure is good, the bright yellow on the boom of the digger is very over-saturated, causing it to lose texture and detail.
At the wide angle end there is fairly significant barrel distortion. I’m beginning to think that these Schneider-Kreuznach lenses aren’t as good as they used to be.
