If you already have the 105mm VR, then for the macro purpose you can get the extra reach via a 1.4X teleconverter (then you even get a 1.4:1 maximum magnification). Of course, this is a choice only if you like the lens and want to keep it.

Hi Frank,
That's - potentially - very interesting..!
Does adding a teleconverter always increase minimum focusing distance? By how much (is it a simple formula)?
I have the 105VR and am finding min. focus distance for 1:1 very close to the front of the lens, particularly with the lens hood fitted. Markus did sort of warn me..!
Could I use a 1.7 TC to increase min. focus distance (reach) more again? And get 1.7:1 magnification?
I guess the downside may be a darker image in the viewfinder with the loss of 1 (1.4TC) or 1.5 (1.7TC) stops on the aperture...
