Canon Zoom Lens J17a x 7.7B4 IRSD SX12

This is a Broadcast television B4 2/3 Zoom Lens with 2 x extender and macro.

It's been well looked after and is generally in good condition.

Includes both lens caps

You can set fast (go to) frame presets with the zoom.

It is suffering from the usual perishing rubber coating that a lot of these lens's seem to suffer from and is a bit sticky.

I'm sure there is some way to clear this up.

It's been stored in a dry place.

I recently connected it to my broadcast camera and it still looks as good as ever, with all functions working.

The zoom started to creep very slowly and then stopped without using the servo rocker, so this, I believe, will need

a small adjustment from a competent engineer. I remember I had it done years ago, so it probably needs another tweak.
