I managed an old style test today. No newspaper so I set up an old product leaflet and took the attached pics at a distance of 20 feet.
Lenses used : Nikon 105mm f2.5 AIS, and Sigma 28-200 f3.5-4.5 Ashperical IF zoom. Nikon TC201 2x converter
Lens aperture was f8 for all shots to give the zoom a realistic chance for image quality. Ideally this lens should be at f11 for best performance. Light levels did not allow f11.
Pics attached
1) A crop of the field of view showing the whole target.
2) Composites of 100% crops at 105mm
3) Composites of 100% crops with converter
4) Composites of the Linhof logo at 105mm and with the converter.
