This medium range scene evaluates sharpness, bokeh, color correction, and depth of field gains of the Zeiss Batis 40mm f/2 CF. A very high dynamic range scene, details in the black tires are of interest in terms of penetrating power under extreme blue light.
Includes images up to full camera resolution from f/2 through f/11.
The Zeiss Batis 40mm f/2 CF looks to be an exceptionally strong performer; see for example (at full resolution at f/2) the spectacular resolving power in the horizontal interior of the headlight and nearby areas.
Winterized with 3/4" high-grade foam insulation along with Reflectix shields for windows, the van stayed 32°F inside with outside temperatures of 19°F for 20 hours. I could take further measures if I anticipated temperatures down to 15°F and lower such as baffling the interior, but I sleep best at 32°F anyway. It takes about 20 minutes of idling to get the interior from 32°F to 70°F, and that also charges my 10 kW battery system. This article and many others were written within this van exactly as seen!
