Oversampling for High Image Quality (Sony NEX-7)
The Sony NEX-7 has a 24-megapixel APS-C sensor, with its 20-megapixel Sony RX100 sibling having an even higher pixel density.
Were these sensors scaled to full-frame at the same pixel density, we would have:
- 56 megapixels (Sony NEX-7).
- 148 megapixels (Sony RX100).
Image quality of future camera can take advantage of high pixel densities to achieve ultra high per-pixel image quality: the elimination of digital artifacts by downsampling a higher resolution sensor to a lower resolution output size. Or, the full resolution can be used natively.
The key points here are that:

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”.
