Hi all, I'm coming to purchase a second (perhaps third who know ...) hand the AIS Micro Nikkor 55mm: the lens are ok BUT the problem is that the diaphram blades doesn't close. I try to explain better: The little lever on the back of the lens is free in moving and isn't locked, instead the INNER one (INTO the lens) is visibilly locked. Now I want know what may be the value of this object and what may be the reparation price to correct this problem. Description of the lens: Micro Nikkor 55mm f2.8 Made in Japan Filters 52mm Focus min @ ~0.20 m S/N 354815 Another little question ... ;-) ... I may buy also a 16mm f2.8 EBC X-Fujinon Fisheye (Fuji mount) ... may it be converted to the Nikon F mount ??? (Someone has never used it ???) Thank You in advance for your answers.
