canon FD 70-200 f4L

<p>Hi<br>

I need cleen fungus inside my zoom fd 70-200 f4L,how the best way to disassemby it?<br>

Thanhs to all</p>

<p>soory,is the FD zoom 80-200f4L</p>

<p>The hardest part of taking a zoom lens apart, is getting it back together again. If you do get it apart, photograph every stage of disassembly, and mark how the helicals go together.....</p>

<p>Additionally, the fungus may well have etched the lens surfaces, so cleaning is not guaranteed to restore the lens. If you can kill the fungus so it stops growing (UV?) you may want to try shooting with it as it is. Sometimes the results can be surprising, as I found out with a badly overgrown mirror lens.</p>

<p>Depending on the moon phase, or some such variable, the eBay "sold" prices of versions of this lens sell for less than a hundred dollars to another mode at around $200-300. My first eBay purchase was to replace a fungus-infested lens that no camera repair person around here would touch. But that's another story....</p>

<p>Thanks,i take off de two first glass in the front,i don´t know thow took the third glass,this one has fungus,i don´t know if the front ring where we put the lens hood,get out or if this ring has a srew.I like to tent clean this lens glass,so if you could help me i apreciate that.<br>

Thanks in advance</p>

<p>Just take it in to a qualified technician, Paulo. Or, as JDM is suggesting, look for another copy. It's a stellar lens.</p>

<p>Do have it cleaned. And get another lens like it. You might use the first lens with teleconverter.</p>

<p>I've salivated over an FD 80-200 4.0 <strong>"L"</strong> for some time...mint / excellent conditions ones seem to go in the $350 - $400 range.<br />Don't want to put any more 'extra' money into the hobby than I need, and this would definitely be a 'want' instead of a 'need'...LOL...so I'd have to do something like sell a spare FD 300/4.0 first, maybe some other lens I rarely use, etc</p>

<p>I've got to stop reading forums...LOL...this thread pushed me over the top !<br /> <br />I bit the bullet and finally got an FD 80-200.4.0-L ...found one for sale by a dealer I've bought a couple lenses from in the past.<br />So far his descriptions have always been 100% accurate...his description of this one is:<br /> <br />Excellent + condition!<br />Body lens: Little sign of use, no dents, no dings<br />Optically: Light dust, no scratches, no haze, no fungus<br />Focus and zoom: Smooth<br />Aperture blades: Clean, oil free, working properly<br /> <br />Been wanting one of these for a long time, hope it lives up to it's reputation. </p>

<p>OK, most of my hunting season is over...re-focusing (no pun intended) on photography...had a chance to test the new Canon FD 80-200/4.0 L lens I picked up in December.<br /> Shot this Cardinal hand held, through a Skylight filter, through the kitchen window, through the storm window, and still got great detail...looks like the lens is a keeper as far as I'm concerned.</p>

<p>These Canon FD 80-200 / 4.0 'L' lenses really are great...this is a 'Rufous Sided Towhee', handheld off the front porch (Sony NEX-7) <br>
