The mistery knob

Hi all,

Finally got myself a big lens. Real cheap too.

My question is : What's the knob on the side for ?

Usually knobs like that are for loosening the mount so that the lens can be rotated and used for verticals etc...this one looks sort of weird though!

Yeah thanks Adam.
That's what I thought it was at first, until I unscrewed it to find that stud sticking out.

It's a Koboron 120-600mm if that's any help.
The resulting photos with this lens are quite surprising. Way way better than I expected.

Figured it out now.

On closer inspection (that I shoulda done earlier) , the knob has a hole in the side of it where there used to be a grub screw.

I fitted a new grub screw, and now the stud will undo to allow the lens to rotate.

Happy now.

10/10 Adam.

Cheers
Chromo.
