I have a manual Micro Nikkor 55mm lens and it stays open at f2.8, i.e. maximum aperture. Anybody knows if it is a simple, low cost job to repair this? Or would it be too much for the value of the lens? I loved this lens because I could take very sharp pictures with it. I live in Montreal, Canada. |

The first incarnation of the 55mm Micro-Nilkkor featured an automatic extra exposure Stop when in close focus. Such was a pain in the posterior. Nikon responded to market forces and dispensed with such feature on later models. I am simply saying that the Micro-Nikkor is a little more complicated than the norm. It is arguably one of the finest lenses ever produced by Nikon and you'd be well advised not to fiddle with it. I would be taking to the Canadian Nikon Importer Service Department and asking for a service estimate. Hope this helps |

This problem is probably caused by the diaphragm blades being sticky with oil. In the 55/2.8 Micro Nikkor the diaphragm is removable from the rear as a unit for cleaning.... it is not difficult or time consuming to do and the repair should not be expensive. A more common problem in this lens is stiff focusing, caused by the extra helical that operates a floating internal element to improve image quality at longer distances. Having this fixed at the same time will increase the cost but it's probably worth doing. |

Thanks a lot for those answers. I will have the lens examined by Nikon for an estimate. I hope it is only caused by the diaphragm blades being sticky with oil. I won't play with it myself, having neither the tools nor the knowledge to do it. |

Hi, My name is Don and I'm from www.procamerarepair.com, we would de-assemble the entire lens and place the diaphragm blades in an ultrasonic cleaner and clean all the optics for about $95+10s/h. If Nikon decides not to repair it, feel free to send it over yonder. Kind regards Don |
