A bit more than two years after shooting the PhaseOne IQ4 in December of 2019, I thought to take a retrospective look at its image quality. Reviewing my images, I remain as impressed as ever that its single-frame image quality remains unbeatable.
When depth of field challenges can be met, the potential for very high resolution images with not so many frames is possible—rotational stitching. This allows a far wider viewing angle at far higher resolution.
Example — Alabama Hills View to Mt Whitney, Lazy Winter Day
This stitch was shot with the Schneider Kreuznach LS 80mm f/2.8 with a finished field of view equivalent to a 40mm lens for the finished image. That longer 80mm focal length (vs 40mm) delivers a result that would in effect would require an 107mm-wide capture area. In other words, the 'feel' from the focal length is like shooting a 4X5 camera with its ~96 X 120mm capture are—and that is one reason to do stitching rather than a wider lens with cropping. The feel would be vastly different had I shot the same scene with a 40mm lens and cropped for this aspect ratio to ~100 megapixels—much larger foreground and much smaller mountains would have resulted. The amount of telephoto compression feels just right.
