    Ever wonder what's inside but don't have one or would not dream of taking apart your expensive baby? Not to worry, I've got tools and no sense so have a look!

    Actually, I get paid to do this kind of stuff. I might even take a file to some of the innards. Wish me luck!

    Anyone have any ideas on reducing the friction in the focus mechanism I'm all ears.

    No worries!

    Lest anyone gets overly concerned I got it all put right back together ship shape.

    I have one, and I refer to it as "my baby" as well. At the price I paid for it- I totally gasped when I saw your pics :smile:

    Out of curiosity- what ARE you doing that for?

    Kills cats and does much damage when misused.

    Trying to figure out how to lessen the friction in the focus mechanism. Can't say why - top secret stuff.

    I've stripped all the grease from the helicoid threads and applied graphite as a lubricant but still not so great. There is tremendous bearing surface in that thread arrangement - I think I need to shave the threads down a bit.

    unless your copy is different to mine, the focussing is perfect, so what on earth are you trying to change?
