Thank you, terence2 - This was actually a test-shot with a brend new Nikon Df, borrowed for a few hours from my friend, a photographer colleague - he was the "model" walking through this old "hole in the wall" an ancient doorway from 1678. I only had the Df in my hands for about 2-3 hours and fell in love with it's files. But, alas - too expensive for my wallet! I usen my own ff-lens on it.
Best regards,
Walter
