Modification of Pre-AI lens to AI

[cpkoh]

Any one knows which camera shops in Singapore can do the modification of Nikon lenses to AI lenses. If so, how much for a 28mm F3.5 lens and is it worth modifying it.

Look like we cannot get anyone in Singapore to do the modification.

Anyone please response if you have any idea.

Thank you very much and I don't think I am competent enough to DIY.

I've not done this for maybe 10 years, but back then Shriro (Nikon agent) did conversion for me for 28/3.5 and 24/2.8.

I think they stopped the service a few years back.

I wonder if they can modify G lenses to include an aperture ring..

Yes, I did sent in my 55mm F/:1.2 for modification and AFAIK they have stopped doring it.

Did you ask TCW? I would have thought they'd do this.

Thank you, I will call them to check whether or not they can do it.

Not sure who else does it now, but i did it myself for some of my lens including a 55, a 135

Simply do some easy calculations on how much to file, then measure. Using a drill file, work off most of the chunky parts and do the fine parts with a small file, then sandpaper. I believe some sec1 D&T syllabus covered that.
