Papa Francisco (in the picture below, adapted from the Vatican newspaper l’Osservatore Romano) was around 380 meters far away from my D800.

In the panel below it is depicted how could I see him with a 50 mm and a 16 mm mounted on my D800. First, second and third column are respectively left, middle, right crops of the full size pictures (f/6.3 and ISO 100 – click here and here for downloading 15 MB full size pictures) Click on the picture panel to see it full size. 

50 mm vs 16 mm

Except for the slight chromatic aberration on the left side of the 16 mm picture (that is automatically removed by lens correction, compare middle and bottom rows), I am happy I had this lens just in time before visiting Rome.
