Ijust purchsed a copy of thi iconic lens from the last non-AI run. I hope it won't be a problem to convert it to AI. Does anybody have experience with Fototechnik Hofmann in STUTTGART?

Conversion rings are gonna be hard to find, but in terms of just filing it down anybody should be able to do that

I wonder why you didn't get an AI lens to begin with? Some just grind off the aperture ring to make it works but I doubt if you hire someone then there is no saving except you consider the older lens is better?

What camera are you going to be using, it is quite usable in stop down metering.

Which 105/2.5? Older Sonnar type or newer double Gauss type?

@Dan Fromm That is the most important question. That is why I bought both.

If you have a Nikon FE you can lift the AI tab.
