Canon EF 85mm f/1.2L II
Expensive, but worth it. Performance in infrared might even be superior to that seen with color use when shot wide open. However, flare can be a problem, so shield the front element carefully. The original version is likely to perform the same way in most respects, but since the lens coatings have changed, it might behave differently with hot spots.
Hot spots are faintly present, but so diffuse as to be a non-issue with most subjects (and who stops down an f/1.2 lens to f/16 anyway?).
Canon EF 85mm f/1.2L II hot spots
As this lens is designed for shooting from f/1.2 to f/4, hot spots aren’t really a priority. Still, the results show that hot spots change little from f/5.6 to f/16, and the shape is diffuse enough to usually be masked by the subject.

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.
