Lens Servicing

Hi guys!
I’ll be sending in my Canon 5D to have the sensor cleaned tomorrow (Friday) or Monday. I’m thinking of sending in my 17-40 & 70-200 L lenses for servicing too while I’m at it. They haven’t been done in years but I’ve not noticed any lens faults. Do you guys ever get lenses serviced without any obvious faults?

The only lens I have had cleaned was my old 'push & pull' 100-400 as it gathered dust internally, apart from that I haven't seen the need.
Clean them yourself and make sure the contacts are clean, as long as they function ok then I wouldn't bother.
I also clean my own sensors, its not that daunting, just watch a few you tube videos and you can save yourself some cash, and also the bother of sending it off.

I've only sent lenses in when they;ve been damaged.
If the lenses still operate normally I wouldn't consider servicing.
If it's peace of mind, get a service quote and then decide if that's ok to put your mind at rest.
As for sensor cleaning it's very straightforward, as you're only cleaning a glass layer on the sensor, not the sensor itself. But if it's something that concerns you then by all means get a service centre to do it. I've cleaned all my cameras ensors with no problem though it did take numerous attempts on a couple of occasions for some stubborn spots. I've not needed to clean them since fortunately.

No never considered sending a camera or lens for servicing. My 5D4 sensor has not yet needed cleaning but when it does, I can easily do it myself, as I have done for previous cameras. The only time I would consider sending a lens anywhere is, if a definite fault has occurred and the lens needs disassembly which should take place in a "Clean room". The largest clean room I have seen is where they assembled the Hubble Telescope.

Hi, My 100-400 also needs cleaning. I sent it to Miles W, but he said there was too much dust inside. Who did yours, please, Pink, and at what cost?
