150MP Phase One IQ4
Schneider Kreuznach LS 80mm f/2.8

Aperture Series: View to White Mountains From Summit of Eureka Dunes (IQ4 150)

This aperture series look at performance of the Schneider Kreuznach LS 80mm f/2.8 on a landscape scene at very far distance. The $65K question given the Phase One IQ4 system is what aperture to use to make use of the fabulous 150MP sensor.

I had wished for beautiful warm light at dusk, but the reality is that this 'blue' scene with a “blue line” lens is a severe challenge for any camera, and is thus a win in seeing what camera and lens can do under difficult conditions—blue light of low contrast.

Includes images up to full 151MP camera resolution (14204 X 10652) from f/2.8 through f/11, plus crops. Also includes 100 megapixel downsampled variants for perspective versus Fujifilm GFX100.
