Shot vertically, the Fujifilm GFX makes an excellent platform for panoramas. The main issue is focusing instability with all the lenses (as documented in detail), particularly with the GF 120/4. This series I was lucky—the lens varied only a little, so nothing was thrown off focus by the GFX in any significant way.
This panorama was shot using the Really Right Stuff PG-02 pano gimbal head. At the time, I had not determined the entrance pupil position for the GF 120/4, but most of the scene is at enough distance that the resulting stitch is free of parallax.
Presented at image sizes up to 85 megapixels.
My feeling is that such images take on more and more appeal as retina-grade 8K displays come to market. While the image is great fun to scroll around in on an 14-.7 megapixel iMac 5K, an 8K display shows nearly 32 megapixels at a time—I look forward to such displays as I have long enjoyed 5K better than any print.
As shown below, 14505' = 4421m Mt Whitney is seen just right of center and above the road-cut of Whitney Portal Road. The peak about 1/3 from left is 12944' = 3945m Lone Pine Peak. Because it is closer, it looks higher than Mt Whitney, which is the highest peak in the lower 48 states. Still, White Mountain Peak at 14252' = 4344m is nearly as high and rideable to the summit on a mountain bike.
