Medical Nikkor 120mm f4
« on: September 04, 2017, 21:40:01 »
Hello again! Is there anybody that have an extra Nikon Power Cord SC-21? It is the cord that goes between the flash battery pack and the lens. I also need an upgrade of that lens with a proper CPU installed.

Sorry, probably can't help you there. I do have a mangled spare somewhere, but firstly it needs resoldering,  and secondly and more importantly, it has to be located :D

As to the idea of putting a CPU into the Medical 120, this is feasible (done this a couple of times and kept one sample for myself), but only meaningful if the linkage between focusing and aperture is severed. This occurs deep inside the innards of the 120 and should be left to a qualified repair tech.

Thank you Bjørn I like to check out a qualified tech for that. I will come back to you for a G type CPU!

Not even Nikon Europe can do the surgery on that medical nikkor 120mm. No tech is able to take on the task!

FotoCare (Oslo) is authorised Nikon repair shop and they can do it :D did this for me - on two different 120 lenses.

I can act as a proxy for you if necessary.

No, I am dropping this upgrade as it is to costly and uncertain! This is the answer I got from Foto Care in Oslo. "The cost of such a job is set at 2850NKR + VAT and shipping.
 
Also important to mention that this is an expired model that we do not share and that is something that is or becomes defective during disassembly, so we can not take responsibility for this or provide warranty for repair.

... sorry about that, but at least they could do the job :D

I'll stick to my own sample of the 120 Medical then, as would Erik. These specimens are getting unique.

Hi All!

Just acquired this beautiful lens, which in great shape, optically speaking.
The problem is that some parts on one of the PCBs are dead, burnt?
The AC-UNIT LA-2 fortunately works fine with my SB-21.

I'm looking for the schematics of course to try to repair it.
Is there any luck I can find such thing?
Thx.

Patrick
