Canon Lens service?

CyberDyneSystems · 22nd of April 2004 (Thu)

Does anyone know if Canon can or will be able to clean/repair a lens that has "Very slight haze" on the elements?

I understand this will cost either way.. but think of a really good deal on a 400mm f/2.8 because fo the haze... if they could fix it it would be a super bargain.

Can Canon clean it/fix it?

I suspect that they could clean it up for you, but I have no idea of the cost. I would guess that depending on where the haze is, it may require a good deal of disassembly or it could be more simple.

Nope, they cannot do that. You might was well send me the lens and I'll use it as a door stop

Based on my experience with the 'gravitationally challenged' 100-400, Canon uses a flat rate for lens repairs. In the case of my lens, it's $299 plus any parts. I would guess that it's the same policy with the 400 f/2.8, although the flat rate is probably different.

My understanding is that they will do whatever is necessary including complete disassembly, reassembly, and calibration. If the haze can simply be cleaned off the optics, the repair should be no more than the flat rate. If the haze is 'terminal, replacing the optics will no doubt be brutally expensive.

Of course I am strictly guessing, but the correct answer probably is, 'depends'. (Somehow, the mention of adult diapers seems appropriate when talking about a cheap 400 f/2.8. I know it would have that effect on me.)

CDS, give them a call and ask them. If you call the general number, you'll get the customer service located in Somewhere, USA but they should be able to tell you if the one in NJ, if that's the closest one to you, can fix/clean the lens for you. They might even be able to give you a qoute on the price.

If you were lucky, then the haze might be some simple water vapor on internal surfaces of the lenses. Cleaning would get that.

If you were unlucky, then the haze might be from magnesium fluoride removed from the front surface of the foremost lens element.
