The lens on my ST-1200 HD reads "Elmo Super Zoom Lens 1:1.3 f=12~25mm Japan". The focus knob does move the lens front and back but I can't rotate the lens to zoom. Does this not zoom?

In the quote of my first post, I typed what's written on the lens. From your words and what my lens says, it looks like my lens is 12 to 25. The lens is pretty beat up as you can see in the pic. However hard I twist, it doesn't rotate.

It was just a thought Tony. Someone may have taken it apart to clean and couldn't get it back together. We've seen stranger things in this hobby....

Or maybe the previous owner has a permanent set up, so didn't need to change the screen size. With the lens glued he was only to worry with the focus. Just a thought.

Hi Ashkay
Try heating the whole lens with a hair dryer or warm it up in the sun. The original lubricant in the zoom thread may have gone hard and caused it to become seized. This has happened to me and the jammed lens came loose again after I left it in the sun for a few hours.
worth trying.

It shouldn't do Winbert,any fogging usually disappears when a lens gets warm.I still feel the lens has seized and needs a bit of help.

It's called RONSONOL Lighter Fuel Made by Ronson.(used in Cigarette Lighters..Don't use near a flame...I've used it to loosen up old stiff binoculars I've collected through the years and works great. Has no lasting grease left behind. Dries up nice...
