Sony 16-35mm f/2.8 GM 3-Way Shootout @ 21mm: Morgan Pond
Includes images up to full resolution from wide open through f/11.
A far field scene was chosen to best show the differences, since far field scenes more easily reveal lens sharpness and asymmetry across a near-far zone. This scene shows something particularly interesting with the Sony 16-35 in stopping down from f/2.8 to f/4.
The behavior of the two zooms is 'wild' enough that this comparison is best appreciated by scrolling around the full resolution images to see the weird things going on. The Zeiss Loxia 21mm f/2.8 anchors the comparison and acts as a reference by showing consistency across the frame.
