Nikon D700-IR with Zeiss ZF 25/2.8 IR Distagon

Reader Phil L sent me his converted Nikon D700 full-spectrum camera (sensor glass is replace to pass visible light, infrared, and UV). Using filters, the image can be infrared or visible or a combination of both. I concentrated on infrared, and today I just received my ZF-IR 25/2.8 Distagon, a special industrial version with coatings that do not attenuate infrared as do the normal versions. See my previous review of the prototypes.

The D700 does a beautiful job in infrared, though Phil requested my input on a sporadic reflection that is apparently a side-effect of the conversion process. I’ve reproduced it, but as yet do not know the cause.

Shown below are two examples shot with the ZF-IR 25/2.8 Distagon and a B+W 093 filter. The high quality of both the lens and camera are evident.
