Hasselblad 63.5-85mm variable extension tube brand_Bilora The Lowepro Dryzone 200 isThis variable extension tube for Hasselblad V series cameras and lenses provides helicoid based continuous extension between 63. 5 85mm. Ideal for close up work in the field, where a bellows may be less practical and this tube maintains shutter firing and lens cocking functions without the need for cable releases. In excellent condition, with minor cosmetic wear.
