Dust or Fungus on my 24-70 f/4, will CPS clean it?

Have recently noticed some dust or possibly fungus on my 24-70 rear element. Would CPS clean this, any ideas? 

 

Thanks in advance. Image.jpeg

The problem with fungus, and I am not sure that is what you have, is it does physical damage to the glass itself.  So simply cleaning it will not fix it.  That is why it must be dealt with as soon as possible. Call Canon and ask 1-800-652-2666.

EOS 1DX and 1D Mk IV, even less and less other stuff.

Canon will definitely repair it. Whether the repair is a cleaning or an element replacement will depend on how bad the problem is. As Ernie says - give them a call.
