D3200 Sharpness from ƒ/4 - ƒ/45

The interest here is not really D3200 per se, but rather an investigation into what a future full-frame ~58-megapixel camera having about the same photosite density could deliver in terms of sharpness. Presumably such a sensor could take a course similar to the D800E, omitting the optical low pass filter.

The APS-C sensor in the 24.2-megapixel Nikon D3200 is 23.2mm wide, versus 35.9mm for full-frame. Consider the same pixel density implemented in a full-frame sensor:

24.2 megapixels * (35.9 / 23.2)^2 = ~ 58 megapixels (9310 X 6190 pixels)

The results seen here can be interpreted as the (minimum) quality one might expect in a ~58 megapixel full-frame DSLR. It is “minimum”, because presumably with another year or two of sensor development and a pro-grade camera and no OLPF, one could expect even higher per-pixel quality.
