Zeiss Otus 55mm f/1.4 APO-Distagon Aperture Series at 50 Megapixels: Summit Building on White Mountain Peak, North View (Canon 5DS R)
Get Zeiss Otus at B&H Photo.
Example images are all up to 24 megapixels in size (with intermediate sizes also).
Snow lice can be seen to be crawling on the snow and building. Watch ’em move across the f/1.4 to f/11 aperture range! The crops include 1/3 stop increments starting at f/5.6 for a detailed look at effects with stopping down.
If you’re going to shoot 50 megapixels (or 36 or 43), shoot Zeiss Otus. Hardly anything else comes close and nothing is better. Well, some aspects are better than riding a mountain bike to 14,252' elevation with a tripod and Canon 5DS R and Zeiss Otus.
For Sony shooters looking to shoot Zeiss Otus on the Sony A7R II with its vibration-free EFC shutter, I recommend the Novoflex lens adapter with the Novoflex ASTAT tripod collar. If buying Otus, the Nikon-mount Zeiss Otus is preferred for its manual aperture ring (no electronics needed in the adapter).
