(sorry, my previous attempt at this post didn't have a subject. Attempt number 2)
Hi, I recently purchased this nice lens. After I received it I heard some rattling.
I removed the front element, and found that the culprit was the large middle element. It's hanging loose and I can move it back and forth a few millimetres!
Only I can't figure out how to get access to it. I can't see a ring holding it in place and I need to get closer for a look.
Anyone know of instructions on deconstructing this lens?
Any help greatly appreciated. The rest is in very good shape so I'm hoping to get it up and running!

I started also disassembling the back end but didn't get any further than this. No idea how to proceed...

Hi Bobby just wondering if it was the same as the 200mm illustrated above to get into the middle element I have 2 of these with working apertures but very dusty inside.
The only lens I managed to clean is the flecktogon and it was very straightforward. I don't think this is going to be the same
Thanks for sharing

It's not a hard lens to work on. If you don't need to get at the blades then don't separate the two parts as shown in my pictures above. If the blades are oily and sticking, remove the glass and flush the blades and mechanism thoroughly with lighter fuel, use the whole can if it needs it - it's cheap.
The glass can be accessed without risking the aperture blades and is easy to get at. But - I dropped one of the inner lenses on to a plastic storage box lid from a height of about 6 inches and a huge piece of the lens broke off, I don't know if the glass is more brittle than other lenses or what caused it break, but I was very surprised.
The 135 and 200 are just about the same as well, my pictures should get you through either lens. _________________ LENSES & CAMERAS FOR SALE.....

@Lloydy, @BobbyB
I have the same lens with broken aperture blades and I would like to repair it.
From your first picture, how did you do it to separate the lens in to two parts ?
