Canon 100mm/3.5 disassembly

[Mephiloco]

I was curious to whether anyone had any experience taking one of these apart. I just acquired one for pretty cheap, but unfortunately it has some haze or maybe fungus on one of the elements. Anyways, any help would be appreciated, as well as any solutions for fungus remediation (save sending the lens off)

The Canon 100/3.5 is only lens that I was able to open and get rid of haze off the elements.Have had a go on others..no luck ..no skill.
Just screw off ring at the back of the lens..thats it.

Save your trouble. What you see on the element is not haze. There was haze on that lens, and the lens was disassembled and cleaned by DAG. What you see it is some residual damage to the element coating.

It doesn't effect the sharpness of the photo, but may leave a bluish cast to the photo under certain lighting conditions. The bluish cast can be corrected with a warming filter.

Oh alright. I figured it'd probably have about the same effect as cleaning marks. I rarely shoot color film so I could care less about color cast. I'm just now finally getting my M2 back from DAG and wanted to make sure there wasn't something wrong that I needed to fix before it got worse
