The lens has not yet found its way to my home
But I was on the lookout today for some Queenstown-like neighborhood to shoot some real-life images at a sufficient distance. Now here is...
Little Bavarian town with the Unremarkables
Shot with the Sigma 150/2.
8 to get a feeling for the angle of view. And to identify landmarks and measure them in Google-maps. So I added the distances to prominent buildings and looked up the cambridgeincolour dof-calculator to get a feeling what the dof would be when focusing with a focal length of 200mm at the building at 2900m distance. And what did I get?
Under normal viewing distances of 1x the diagonal of the image and 20/20 eyesight I get acceptable sharpness from 1200m to infinity. But if you magnify the image to 100% presentation (of a crop) on screen you're approximately 2.5-3.0x closer to the image. Putting those figures into the calculator it delivered a 2000-5600m "field of acceptable sharpness". Now that means you can not
judge sharpness at the closest buildings at 1600m because they are no longer inside the dof.
Now I only have to wait for the lens (not for too long) and clear, sunny weather. Well, the forecast for next week is not looking too good
So perhaps I'll shoot some Siemens-stars at first
