Re: MTF charts for first four S lenses
I agree that the curves must be the standard 5, 10, 20, 40 (two coarse, two fine values). The dark and light lines are radial and tangential resolution, I suppose, but which is which? And what is the horizontal axis? It's distance from the center of the image as a fraction of something, but is that the image diagonal, the horizontal extent, or what? The faint writing didn't answer that for me.
They do look very crisp across the field at f/5.6 (a good artificial light working setting) but a touch soft at the edges wide open.
