Loose Top of Canon FE 70-200 F2.8 IS (Not II or III)

[subcreative]

Hi everyone. I recently picked up a 70-200 lens quite cheap. I noticed upon receiving it that the top / inner part of the lens has allot of play in it. I read that this is often caused by loose screws under the focus grip but after some exploration, they appear to be tight. 

Here is a short video of what is happening - https://youtube.com/shorts/fOudlCswZxo?si=IbUl2LCC_OTH5rdV

Any advice regarding what is happening, and if it's indeed just the screws that need tightening, I'd greatly appreciate it.

Greetings ,

This is probably not something that can be easily diagnosed in a forum on the internet.  I don't believe the mk1 version of this lens is still serviceable by Canon.  I think it reached its end of service life in 2017.  

Parts could be hard to come by.  You can try searching for local camera repair using your ZIP code.  If you have the option to return it, that might also be a good idea. The party who sold you this lens must have known about the play.  Maybe others will have suggestions?

Hmm. Was this purchased online? Return policy?

I think you could fix this!
I just recently bought a beat up original version (not IS). I briefly considered replacing the front elements and found a few videos on youtube showing how the front part comes off.I didnt go ahead with it but it doesnt look hard to do!
Does this video may show your exact problem? https://www.youtube.com/watch?v=DpiauO9xeO8
There's a slight chance that tightening the screws doesn't perfectly center the front elements,but it's absolutely worth a try as you wont be making it worse.

FWIW i'm not qualified but have worked on dozens of lenses.Some general advice: Use screwdrivers that fit well.
Always use both hands to guide the screwdriver! It's super easy to make small mistakes.It's safest to use a plastic tool for wrangling the rubber grip off
