I've had this lens for quitea while.

It worked just fine for the longest time, then it started rattling

Having nothing to lose, took it apart.

Well, theres two lenses (2d and 3d from the front) that fell out.

They're spherical and fit into one-another (kinda like spooning)

So, do the go like this:

Front (( camera OR

Front )) camera

I'm sure we have some super guru who knows!!!!!!!!!!!!

If you are referring to the Korean made (Samyang??) lens with the barrel that rotates to select macro mode, I hope you can get it back together. For a cheap lens marketed by Sears it is incredible, I get sharp, high contrast images from mine that rivals my Rikenon 135mm f2.8 for quality.

Good luck, it is a surpizingly good lens.

PS, just did a test of mine, the attached image is a 100% crop at 200mm out my back window (through the glass). The image info is on the image. Note: These images have not been altered in any way except a little compression to get the file size down. They represent a 100% crop of a jpeg image downloaded from the camera and then cropped and combined, no sharpening, no levels adjustment, nothing.

Well, they didn't tighten down their stuff well.

Fortunatly, I have a compliment of auto tools with which to work on the lens. :-)

It's amazingly complicated, and appears well made.

If I put the lenses in wrong perhaps I'll have a 12-50mm or a 200-800, or some sick macro ...

Hey, a super macro zoom that doesn't focus past 2 meters could be interesting.

Do hope you get it working, it is no match for an FA* Pentax but there are very few constant aperture AF zooms so on a budget the old MF stuff will have to do. The image quality is good and I find it easier to focus than most of my old MF lenses. Too bad the focus ring rotates in the wrong direction.
