Originally posted by ismaelg Do you have a picture of the lens? I suppose the 4 larger ones are for the mount. Usually, to remove the rear element you only remove retaining rings, not screws. But I can't be sure on this case. Post pictures so we can all participate in this virtual surgery
Thanks,
Finally got around to taking some pics. As stated before, I was able to do a quick cleaning since the lens barrell unscrewed as I was trying to unscrew a front retaining ring.
As you can see in the front pic, there's no slots like in the rear photo. Could it be that it doesn't unscrew from the front?
Anyway, when I get to working on this, especially the rear element, which rings will I need to unscrew to get at the rear element?
Will I need to do anything with the mount screws, or is that only if I needed to work on the aperture blades?
Thanks for the advice,
