Coastal Optics
60mm f/4 UV-VIS-IR APO macro

Aperture Series: Bishop Creek Rushing (Nikon Z7)

See Sprinter Halogen Headlamp Closeup for a general description of what to expect from the Coastal Optics 60/4 as well as adapting it to mirrorless cameras.

This series and the others shot at Bishop Creek under similar conditions of blue mountain shadow light at dusk all put the color correction to the test.

As there is little to criticize except that the Coastal 60/4 is not at full performance wide open at f/4, this is a show-and-tell series of what a lens can deliver 45 megapixels when it is perfectly corrected for secondary color and very sharp with a little stopping down.

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 28 megapixels filling up to 5K display, 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.
