Two models, one frustrating, one misbehaving
The light was failing, so the series ends at f/8 with a 30-second exposure, which is the maximum exposure time possible without resorting to Bulb mode and a manual release (which I did not have). The arbitrary capping of exposure time to 30 seconds shows flawed design judgment. It’s frustrating to be there and want to make a 60 second exposure, but to stymied by an arbitrary limit.
This scene was also shot with the 24-megapixel Sony A7, but the camera misfocused so badly that it was not usable even stopped down to f/8. In short, the “better” autofocus of the A7 failed to perform. It appears that both cameras focus at the leading edge of the sharp field.
