60mm f/4 UV-VIS-IR APO macro
Closeup Comparison vs Coastal 60/4
On this page are compared the Nikon 60mm f/2.8G ED against the Coastal Optics 60mm f/4 UV-VIS-IR APO macro in terms of working distance and color correction.
Both lenses were shot without moving the camera, which was locked into place on a tripod.
Focal length shortening
Observe that the Nikon AF-S 60mm f/2.8G ED shows a notably wider field of view at this close range than the Coastal 60/4, the opposite of the finding near infinity focus.
The wider field of view is almost certainly the result of the focal-length shortening tricks used to focus to 1:1. This focal length “breathing” is intolerable to video users, but for still photographers it raises a practical issues: the wider angle of view means a correspondingly closer working distance needed to obtain the same magnification. This can make it more difficult to light the subject, especially at 1:1.

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.
