Full review of the Coastal Optics 60mm f/4 UV-VIS-IR APO MACRO is found in DAP.
This section shows photographs taken with the Coastal 60/4 APO macro in infrared.
Because most cameras converted for infrared have had their focus adjusted for “average” lenses that strongly backfocus (focus behind what is seen in visible light), the Coastal 60/4 can front-focus on some cameras since it has zero focus shift from UV through IR. This means that accurate focus might require some trial and error (shoot, zoom in on the camera LCD, adjust focus, etc). The author’s Canon EOS 5D-IR suffers from this problem but his Nikon D70-IR does not.
The performance seen in infrared is limited largely by focus accuracy (and sensor digital artifacts and Bayer interpolation). It’s a shame that a monochrome sensor is not available to exploit the stunning sharpness of the 60/4.

Examples below are all in infrared.
It just doesn’t get any better than the level of detail seen in the next two images. Careful attention was paid to focus, and even though the 60/4 was stopped down beyond its optimal f/5.6 aperture, the results are still stunning. Click to see actual-pixels crops.
