Phase One IQ4 + Schneider Kreuznach LS 150mm f/2.8 Aperture Series: MemChu

This aperture series look at performance of the Schneider Kreuznach LS 150mm f/2.8 on a planar target at far distance with much more near to-far detail than in the mosaic series. The detail in the tiles of the mosaic is at a much smaller scale than in the mosaic series, which is helpful in seeing which aperture is really optimal.

This series is also a demonstration of the superb image quality of the Phase One IQ4. I might have to shoot it again though, if I can get just the right lighting at dusk, which should be awesome compared to this fairly ordinary morning lighting.

Phase One IQ4 + Schneider Kreuznach LS 150mm f/2.8 Aperture Series: MemChu

Includes images up to full 150MP camera resolution (14204 X 10652) from f/2.8 through f/11, plus crops.

I am eager to do my field shooting, but hazardous winter conditions have delayed my departure.

The fabulous sensor quality of the Phase One IQ4 has a wonderful synergy with the 150/2.8. It makes me wonder just how well the Phase One IQ4 Achromatic could do on a highly detailed scene like this, not that I’d really want to lose the color—but 150MP at this quality would be incredible (better actually, since no Bayer matrix and filtration can be used).
