I was just wondering, bought a "crappy" Elmo lens on eBay, had some marks on the inside. How to dismantle and clean the lens? Is it screwed on, glued on (ie not possible to open) or what?

And what do you clean it with?

Thank you

Hi Vidar,
There is no glue if its the 1.1/1.2/1.4/1.0 lens. You just need a Lens Spammer tool. It will allow you to remove the rings that hold the lens in place.
Then you can clean using Cold Cream. That's what I used when I had to clean a Schneider Lens. For the Elmo lens I just used warm water and soap and it removed the fog.
Now if its the 1.3 lens..I believe you cannot take those apart. They are glued in. Maybe you should get a 1.1? Hint hint..I have one for sale? [Smile]

Good Luck!

I bought ELMO Zoom Lens Super F:1.1 f/1.1 12,5 - 25mm for about 20 dollars and it did say it had problems. Just thought it was cheap and might be salvaged :-/

I am fairly sure I can't get anything to open the lens with here in Norway, so next question ... Are they available for sale?

How much you want for your lens? And it will fit a ST-1200D MO?

Thanks for the reply

Hi Rik, what size lens wrench will I need for the Elmo 1.0? There are a lot of different versions on eBay, and I want to get the right size. I know the big outer lens on the 1.0 is easy to remove and clean, but I would really like to get at the inner one. Please e-mail me, or a reply or link here would be fine. Thanks!

Hi Joe,
I got this spammer from Sk Grimes. They are the same company that was able to shave down the 1.0 Ektar Lens so it would fit in the Eumig 938/940. They do great work and they also make a great product. While it is a little more expensive than the ones on Ebay I know that I wont be buying another one anytime soon. I got the pair.

Good luck!

I’ve used two small flat screwdrivers and drilled two small holes to the required diameter in a bit of wood pushing them through the holes with a tight fit before now. Screwdriver set £1 from a pound shop. Sounds a bit Heath Robinson but it enabled me to dismantle a lens OK and clean up. [Cool]

From that it sounds like there's nothing inside that need to be pushed or anything ??? Is it enough just to twist it off using the the two holes in the lens? If there's no locking mechanism inside, I think maybe that's a nice solution, Lee

Thanks for the link Rik, and thanks for sharing your method Lee, a cheaper alternative. Since I have several lenses I may need to disassemble, I'm going to invest in a tool. Good luck with your lens Vidar!
