Film size ?

Shooting distance ?

[karl french]

It's totally unrealistic to remove the cost in this situation. But the question really boils down to "Do you like the way modern multicoated lens render an image or classic non or single coated lenses render and image." The Dagor will throw a bigger circle but the Nikon will seem sharper within the circle it renders.
