Lenses for Nikon
Please see the Lenses page for important background information, including the lens rating system, with its discussion of hot spots, backfocus and sharpness.
There is wide variation in lens performance in terms of autofocus accuracy (backfocus), hot spot problems and sharpness. Take the time to understand how your lenses perform under varying conditions on your particular camera—unlike color photography, the type of infrared camera conversion is a non-standard factor that precludes accurate generalizations.
Lens assessments are based on my particular Nikon D70 converted for infrared use by irdigital.net using internal sensor glass with an (alleged) 800nm nanometer cutoff. Focusing and hot spot performance could differ with other conversions of the D70/D70s, even those by irdigital.net. In particular, it’s possible that a conversion using glass instead of hard-coated plastic (as in my D70) might behave differently with respect to hot spots.

Diglloyd Infrared Photography covers cameras and lenses for infrared photography.
The coverage explains all the issues involved in shooting for monochrome and in infrared. It is not a review of any particular camera or lens, though many examples are included.
- Monochrome vs color cameras.
- Post processing for monochrome.
- Guidance on workflow for infrared, including black and white and channel swapping for false-color images.
- How infrared renders, and why certain spectral cutoffs matter: false color vs black and white.
- Image quality issues to be on the lookout for in infrared.
- Numerous lens evaluations in infrared.
View an overview of infrared as well as filter spectral transmission plus examples from an optimal lens.
