The D810 as a 73-Megapixel Medium Format Camera with a 49mm X 36mm Virtual Sensor: Nikon 19mm f/4E ED PC-E Shift-Lens Stitching (Alpine Creek)

See my wish lists at B&H Photo including my Nikon wish list.

See reviews of tilt/shift lenses in DAP.

Update: I’ve added large crops as well as this page:

Nikon 19mm f/4E ED PC-E Aperture Series: Shifting for Stitching: Virtual Sensor of Up To 49mm X 36mm

...

This page builds on the initial shift-lens stitching examples with the Nikon 19/4E PC-E.

This particular 73-megapixel example includes an annotated finished image along with a discussion of what focusing choices were made.

To be able to double the camera resolution quickly in the field, with minimal post-processing is a huge win for the Nikon 19mm f/4E PC-E. It makes the Nikon D810 into a 73 megapixel camera with a huge virtual sensor area.

Shift-lens stitching has always been possible but never worth the trouble before: I have tested about ten other shift/tilt-shift lenses over the years (Nikon, Canon, Olympus, Mamiya), and not one of them can approach the Nikon 19/4E in image quality. The 19/4E ED is thus a breakthrough lens.

Nikon 19mm f/4E ED PC-E Aperture Series: Shifting for Stitching: Double the Camera Megapixels (Alpine Creek)

Includes images up to 36 megapixels.

The aspect ratio after cropping is 1.37:1, which is only trivially different than the 4:3 aspect ratio of many medium format cameras (a bit of cropping would yield 1.33:1). Thus what we have here is essentially an image competing and beating most every medium format camera. And at an angle of view not even available on medium format, that is, in focal length terms: 19mm along the short axis of the finished image, and approximately 15mm along the long axis. In other words, the rough equivalent of a 19mm medium format lens.
