Fungus in my A35-70 f:3.5-4.5

Has anybody taken one of these apart ?

I've noticed some fungus inside the rear element of my A35-70 f:3.5-4.5, and I'm wondering if it's feasible to pull it apart to fix it ?

It's my favourite walkabout "one lens, chuck it anywhere, don't mind if it gets banged up" on my old K-x. IQ isn't the best but it's OK, I love the colours, and the "macro" I find really useful. And it's tiny.

It's obviously not worth paying for a pro job, but if the alternative is that it becomes a paperweight then I figure I may as well have a go myself.

Any pointers ?

Cheers...Ian.

Rear elements are usually straightforward although I haven't looked at this particular lens before (the F series one is easy). Just take off the aperture lever guard and unscrew the rear element holder.

Thanks for the encouragement !

Turns out it was just a case of unscrewing the rear element. A doddle

Many thanks.
