On this page are compared the Canon 5D Mark II using the Canon 85mm f/1.2L II (“85/1.2L” on this page), and 85mm f/1.8. The Nikon 85mm f/1.4G is also included, with the 24MP Nikon D3x images downsampled to match the Canon resolution.
Note that this is a comparison setting aside the qualities of out of focus blur for which the 85/1.2L II is well known. As such it should not be used alone in making a lens choice, but rather as one consideration in light of intended usage.
Series at 1/5000 sec @ f/1.2, 1/4000 @ f/1.4, 1/2000 for f/2, etc.
Apertures in 1/3 stop increments used from f/1.2 through f/2.8, full stops thereafter. This helps show just when things start to improve.

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.
