Three different details from three different areas of a 6×9 frame from the Voigtlander Bessa I. No. 1 is right in the corner, and heavy focus blur can be seen. No. 2 is along the bottom edge but about 20% in from the short side, where focus is acceptably sharp all around; No. 3 is near the center of the frame and focus is quite sharp and even throughout this sample area.
