My current favorite macro setup. No AF, no VR, variable, but in practice fixed reproduction ratio, but, With fast EVF, IBIS, and, since firmware upgrade 2.0 instant zoom-in zoom-out capability. Since 2.0 even full lens description , aperture etc. In EXIF. PB-4 even enables Scheimpflug, very handy with the, per defenition, shallow DOF in macro. Used this set up to get the fly - and dragonfly pics that I posted. Hand held.
Love the discussion going on about the different set-ups and their in and outs!
