Chipping a Nikkor - A Walk-through
Erik Lund:
I don't think Bjørn's CPU's are expensive, especially since they are same quality/identical to Nikon parts ;)
They come highly recommended!
Dandelion CPU's are very fragile, and really the only application where I can say they work on a heavily used lens is for the 50mm 1.2 Ais, where it can be integrated into the F-Mount.
richardHaw:
Thanks! yes, dandelion! all i know is that it was named after a flower starting with the letter d.
i am hoping to chip my lenses without any modification or at best minimal...
now, since nobody is offering this service here in japan, maybe i can start offering the service myself...
Bjørn Rørslett:
I am luckily in a position where I can order Nikon parts such as the factory contact assemblies and their specialised screws. Or in principle any other part in their vast inventory. The pricing policy of such items is 'strange' to put it mildly and most stuff can be frightfully expensive, so if you build an entire new camera from spare parts it'll probably cost 10x or more the street price. The contact block parts come in a middle position and getting the blocks as factory spares can be cheaper than buying junked lenses to scavenge parts from. Plus most junk lenses are cheap consumer 'kit' zooms that use inferior components and their contact assemblies are often plastic-based, not metal as the genuine stuff.
richardHaw:
not sure if i can do that myself! :o :o :o
in the past 10 years of my career, i actually do more programming and technical stuff than creative things but i still lack the practical electrical engineering skills do produce these chips! (apart from photo-etching,etc)
how much do these chips cost? the dandelion ones cost around JPY3000 each I think that is way beyond my budget :-[
Bjørn Rørslett:
I usually sell them for USD 45-50* each plus shipping and handling. Thus the unit price depends on the number ordered.* recent prices have been higher as parts cost apparently increase exponentially over time
