Nikon 45mm f/2.8P (on 5D)
An outstanding performer on the Canon EOS 5D. It’s a real winner: very high sharpness, no hot spots, diminutive size, and minimal weight—140g without caps, but with filter and hood. It’s a superb choice for a small and light shooting rig—the 5D dwarfs the lens.
Backfocus is modest, but it must be accounted for in order to achieve critically sharp results. Stopping down to f/11 can mostly overcome the backfocus issues, but some subjects simply will not yield optimal results unless care is taken. Fortunately, the focus correction is easily learned; the best technique is simply to get in the habit of focusing slightly in front of the subject.
As with all Nikon lenses on Canon bodies, focus and stopping down are a manual process. Still, operation is relatively quick and easy, and no problem at all for static subjects.

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.
