More PhotoGeekery: Finite Conjugate MTF Bench Tests for Macro Lenses
For the last several years we’ve talked about the fact that lens performance can vary with focusing distance. Our optical bench tests at infinity. Computerized target analysis (Imatest and DxO) tests at close distances. But when the results of target analysis and bench tests differ it’s hard to decide if the difference is because of different testing […]
