Can anyone recommend where to send it? I'm half tempted to DIY but have no way of calibrating after.
I went the diy route with an older lense. Wasn't too bad. Getting the lenses clean (like immaculately dust free) was the hardest bit. Calibrating as in getting Infinity focus at infinity? There was a trick to diy that. I seem to recall it involved putting 2 lenses end to end? Something like that. A bit of googling got me there.
I cant seem to find a teardown anywhere. Dont want to potentially bork a £1k lens
If it is genuinely worth £1k then I'd probably get a pro to sort it out, rather than risk knackering it permanently.
I am keen to try this myself.
But I would definitely try it out on an old one that is OK to trash first.
Not been brave enough yet.
As I understand it, the zooms are more 'interesting' than primes.
(more moving parts).
I also suspect the newer lenses (which, by the sound of the value, this is) are more intricate.
Depends how mouldy it is.. If its growing on the elements, you will never get it off completely- the mould will have pitted coatings, or in some extreme cases, the glass.
Found a decent Yt video someone posted this month. I've had an L series 24-70 apart that was damaged
