Hi Folks,
Just wondering if you would risk buying a water damaged fast Canon EOS L glass? I wonder if economical would it be to get one fiexed by a third party repairer? May be too risky or stupid to buy one?
Thanks.  |

Autofocus lens means motor and motors do not like water.
Optical glass does neither, but perhaps with a professional cleaning one might eradicate the risk of fungus.
For motor however it's different and I would not spend my money on a water damaged autofocus lens.
But actually I would not spend money on any autofocus lens  so my case may be an exception.

You're right Orio. I guess looking at that big "f1.2" hunk of glass is very tempting  But on the hand no point having it if you can't focus on anything. |

You still can focus manually. Hopefully.

I think most repair workshops will repair it to fully working conditio only. Because of this it would cost much - probably more than a used or even new working one.
I have bought a EF 100/2.8 macro with water damage, but at the moment didn´t opend it as much as possible to clean and repair it to get it as manual focus lens. The internal building is more complex than on those MF lenses I have opend that much. For the 50/1.2 I suppose a high complexity too. It is not easy to have access to all non cemmented lens surfaces.
I think for 100-200 USD I would be tempted to buy it, but not more.

Is that possible with a AF EOS camera lens. I thought nothing moves once the motor is damaged. However, Nikkor (non G) AF lens are different. MF is not a problem. |

Well this was the outcome:

Also interestingly, I got a reply from the repairer:
Hi Simon,
The lens must be inspected to assess the degree of damage. Generally, if
the lens was submerged in water, it is best used as a paper weight or door
stopper.
Regards,
Jeremy Chua
