I am using a 62mm polarizing filter on my 105mm micro vr lens with the HB-38 hood mounted. While looking through the viewfinder, I manipulate the filter ring by reaching around the front of the hood, extending a finger into the hood, and moving the ring with my fingertip, being careful not to touch glass. The maneuver is a bit awkward, but it works.
I am currently researching the feasibility of using the Nikon HN-30 screw-on hood in lieu of the HB-38 hood in the hope that screwing the hood to the outer ring of the polarizing filter will allow me to turn the ring by grasping the hood. However, the HN-30 is designed for a 200mm focal length lens, and the hood might be too deep for the 105mm lens, resulting in vignetting.
