Sony FE 20mm f/1.8G: Sometimes a Fast Lens Is Needed to Get the Shot
The wind was violent, and even hiding behind a house-sized boulder I was unable to make any sharp images at any aperture other than f/1.8 while the peak color lasted—not even f/2.8 and not even trying multiple times—rather frustrating! And I would have liked to make a panorama too, but not feasible. A bit later after the color had faded, I was able to make mostly sharp images at f/7.1.
Sharpness across the frame suffers accordingly and yet the overall contrast characteristics of the Sony FE 20mm f/1.8G make the result a winner—thus an argument for a reasonably fast lens.

Today and the past several days, the wind has precluded most photography—I just cannot count on getting a sharp image, even hiding behind house-sized rock formations. There is supposed to be rain coming for several days, so that should be super, and I hope it means snow down to 6000' or so, for beauty on the Mt Whitney range.
Fifteen minutes later, the wind settled just enough to make a reasonably sharp image.
