A little confusion here - the ring needs replacing as it is split - I have effected a temporary repair but would like to replace it.

The focusing is very smooth, it just takes more effort than a brush with the little finger!

I have partly disassembled the lens (without disturbing the optics) and it is not the friction brake causing the resistance.

This is the only manual focus lens I have got and it certainly isn't as free as the AF lenses, so I was just asking whether this is normal behaviour for my lens - especially as it has two sets of helicoids.
