That lens is notoriously bad I'm afraid. It debuted during the film era (not a good era for EF lenses). It does have some historical significance as the IS version was the first image stabilized lens. The plus side is that you didn't overpay for it and the 50/1.8 is a good lens.
The Canon 70
-300 is a much, much better lens, though it comes with a higher price tag. The 55-250, as sub suggests, is a good compromise. It's cheap, still has some reach, and produces fairly sharp images.

I was able to use the inside measure parts on the back of the caliper as a spanner and remove the front element group, I was also able to easily disassemble the rear lens mount and aperture control ring to get to the rear element group. Unfortunately a little bit of the fungus appears to be on the inside of the groups, which I was not able to get open with my makeshift spanner wrench, however I did get the majority of the fungus out of the way. I am also left with some haze that is in between the last elements that I was not able to remove either.
sorry for the cellphone pics, I just did not feel like having to bust out the DSLR and import photos etc etc.
in the lower left of the lens you can see the fungus still. That was inside the group, I could not get to it, but this is much better then how it looked before.
I took a few test shots with this lens after the cleaning, and as it stands now, the fungus that it has does not effect IQ in any way. I just want to do what I can to ensure that the fungus will not spread further.
I read that sitting it in sunlight for a day or two will kill the remaining fungus and prevent the spread. Is there any truth to this?
I can get access to a food dehydrator that would be large enough to fit this lens into. The dehydrator would be able to keep the lens at a constant temperature in a 100% moisture free environment, do you think it would be beneficial to subject this thing to 150*F of dehydrating overnight?
Also should I be worried about sticking this lens in a camera bag with my other lenses? I have read that fungus supposedly can spread. I have never had a lens infected with fungus before so I do not know whether there is any truth in any of this. I would rather be safe then sorry though.
LOL, in a moment of haziness, I almost posted "Wow, great view you have out your window!"
I believe they call that a "trompe l'oeil".
Very nice (but pricey as usual), but I still want the Zeiss 21/2.8 instead.
