Diffraction Limits for High Resolution DSLR (Dolls, Nikon D7100)
This example used the Nikon D7100, a 24-megapixel DX-crop sensor which does not have an anti-aliasing filter. Pixel density if scaled to full frame would be 56.0 megapixels, a realistic prospect by late 2013 (this example written in March 2013).
There are three things that make this example particularly instructive:
- A sensor with photosite/pixel density equivalent to a whopping 56-megapixel full-frame DSLR.
- A sensor without an anti-aliasing filter (optical low pass filter), thus allowing maximal lens performance to be acquired.
- A world-class lens, perhaps the highest performing DSLR lens available in 2013: the Zeiss 135mm f/2 APO-Sonnar.

Diglloyd Making Sharp Images articulates years of best practices and how-to, painstakingly learned over a decade of camera and lens evaluation.
Save yourself those years of trial and error by jump-starting your photographic technical execution when making the image. The best lens or camera is handicapped if the photographer fails to master perfect shot discipline. High-resolution digital cameras are unforgiving of errors, at least if one wants the best possible results.
- Eases into photographic challenges with an introductory section.
- Covers aspects of digital sensor technology that relate to getting the best image quality.
- Technique section discusses every aspect of making a sharp image handheld or on a tripod.
- Depth of field and how to bypass depth of field limitations via focus stacking.
- Optical aberrations: what they are, what they look like, and what to do about them.
- MTF, field curvature, focus shift: insight into the limitations of lab tests and why imaging performance is far more complex than it appears.
- Optical aberrations: what they are, what they look like, and what to do about them.
- How to test a lens for a “bad sample”.
