This aperture series from f/1.9 through f/9 evaluates the near-to-far distance of the Hasselblad XCD 80mm f/1.9 including sharpness and overall lens correction, and how depth of field develops with stopping down.
Includes images up to full camera resolution.
In spite of manual focus (which should therefore not change), I had a very difficult time with the 80/1.9 for this series, with the same behavior elsewhere over and over: the lens kept going out of focus after taking a frame. See Unstable Lens Focus with Hasselblad XCD 80mm f/1.9. I was forced to refocus for every frame, but forgot to do so for f/11, which ruined f/11 so it is not included. The camera was also beginning to have difficulty focusing, so it is a real mess to deal with this problem under such conditions—use manual focus.
