Voigtlander 50mm f/2 APO-Lanthar Aperture Series: Alabama Hills Plain View to Mt Whitney Range, Pre-Dawn (Sony A7R IV)
This series from f/2 through f/5.6 shows the spectacular total optical correction of the Voigtlander 50mm f/2 APO-Lanthar in intense blue pre-dawn mountain light, blue light being the hardest to correct, a serious challenge to any lens. The air is of an unusual clarity (no dust or smoke) and because of the sub-freezing cold it also has no atmospheric distortion—that combination is hard to come by.
Includes images up to full camera resolution.
I like this image a lot because it shows the Alabama Hills from a vantage point that shows the main plain (very popular area), along with Mt Whitney and nearby peaks, a sum total that I had never seen before, never having been at this vantage point, nor do 99% of visitors.
