Macro Lens Working Distances

working distance

Working Distance is the measurement from the front of the lens to the subject. It does not include lens hood; it's the measurement from the focus plane on the subject to the middle of the front element of the lens

The following data is from my field notes compiled when using these lenses, coupled with known published manufacturer specs. There can be small variabilities to these numbers due to differences in measurement techniques. 

Nikon Lenses
Note that all Micro-Nikkors use a combination of focal length and focus extension to get to 1:1 (life-size) magnification ratios, which also impacts the maximum aperture value reported.
