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.
