Here we compare lens performance on a planar (flat) target at a focus distance that is very close to infinity.
Macro lenses are generally corrected for a flat field (no field curvature) for closeup work, but even world-class lenses like the Leica 100mm f/2.8 APO-Macro-Elmarit-R exhibit significant field curvature when focused near infinity. Therefore it must not be assumed that a macro lens has a flat field for general use at any distance. However, a flat field is a very useful characteristic, because it allows top performance at wide apertures for planar subjects, including landscapes.
Let’s see how the Nikon 60mm f/2.8G ED stacks up against these two lenses:
- Nikon 60mm f/2.8D (its predecessor);
- The superlative Coastal Optics 60mm f/4 UV-VIS-IR APO macro.
