The reader is strongly advised to read the lens evaluation notes.
This page evaluates the Nikon AF-S 50mm f/1.4G and AF-S 50mm f/1.8G. The f/1.4 lens costs slightly more than twice as much as the f/1.8 lens, being 2/3 stop faster. But is it a better lens?
Both lenses were focused the same way (contrast detect AF at maximum magnification). Both appear well focused at center, and follow similar behavior as stopped down.
No guarantee can be made that the zone of focus was ideal for either lens. Nor is any evaluation made for focus shift, which could be present in both lenses (more likelihood of that with the 50/1.4G).

Diglloyd DAP is DSLR-oriented, but also contains workflow and other topics. Much of the focus is on Canon and Nikon but also Pentax and Pentax medium format.
Special emphasis is placed on lens evaluation, focusing on Canon and Nikon and Sigma lenses, but with a few others like Rokinon/Samyang.
- Make better images by learning how to get the best results right away.
- Save money by choosing the right lens for your needs the first time, particularly some of the new Sigma Art lenses vs Nikon and Canon.
- Workflow discusses image organization, raw conversion and post processing. Many examples show processing parameters for direct insight into how the image was converted.
- Jaw-dropping image quality found nowhere else utilizing Retina-grade images up to full camera resolution, plus large crops [past 2 years or so].
- Real world examples with insights found nowhere else. Make sharper images just by understanding lens behavior you won’t read about elsewhere.
- Aperture series from wide open through stopped down, showing the full range of lens performance and bokeh.
- Optical quality analysis of field curvature, focus shift, sharpness, flare, distortion, and performance in the field.
