This specific 'Di' model (272E) does not feature Vibration Compensation (VC). A tripod is recommended for high-magnification macro work.
The lens uses a 55mm front filter thread for attaching polarizers or ND filters.
Absolutely. The 90mm focal length and f/2.8 aperture provide excellent subject separation and flattering compression for headshots.
