To capture 1:1 (life-size) with my Nikkor 105-mm macro lens, my WD is approximately 6-inches.
A 150-mm macro lens requires approx. 9-inches WD, and
a 200-mm macro lens requires approx. 12-inches WD.
I normally shoot macro between 9-inches to 12-inches WD for better DOF, then crop final image to desired magnification.
Sounds like the extra cost doesn't buy much - at least in terms of WD. Thanks for the prompt response.
