I am looking at purchasing the Canon 500mm f4, however there is significant dust an it will need to be cleaned. Does anyone have a ballpark number on what a cleaning cost would be to remove the dust from Canon?

I understand that no two cleanings are the same. I am just looking for a ballpark to negotiate the price for.

Thank you.

I don't think you can negotiate. Each lens probably has a fixed price for cleaning. I would guess 200-300 for that lens.

Are you apart of CPS? Try sending it in for a check/clean and get it done free.

Richard's not looking to negotiate the cleaning price, he's looking to negotiate the purchase price...


some fairly old canon camera stuff, canon lenses, Manfrotto "thingy", and an M5, also an M6 that has had a 720nm filter bolted onto the sensor:

Thanks for the help thus far. And Joe, you are on the money there. I was guessing around $250 for a full cleaning and servicing by Canon, but was wondering what other's experience was. Also, it appears that I can send it to NJ or to Newport News, VA. Any difference in the locations?

You can always call Canon NJ and see if they will give you a flat rate price for cleaning only. Although I know they tend to avoid quoting anything. But I would expect 250, give or take.

Are you sure the dust is internal? On my 500L whenever I look down the lens and see any spots. 99.9% of the time it's on the drop in filter at the back of the lens. This is the first piece of glass that any dust or dirt will hit that enters the back of the lens. Pull the filter out and wipe it off first and then look down the lens.

Chris,

Thank you for the idea there! I will do that as soon as possible. I hope that it is this simple, but we will see.

You're welcome, I hope that's all it needs. Also check the rear element behind the filter. That is about as deep as you can clean yourself on this lens. Front element, filter and the back of the rear element. The lens is sealed very well so chances are that's the only place you'll find dirt or dust.

Maybe the person selling th 500mm has considered the dust and priced the lens accordingly. In other words, a clean, no dust lens would be $250 more.

Be careful, when I bought my 500L used, I thought I saw some dust. I sent it to Canon and they said it was mold. Needless to say I was disappointed.

I sent it to my local camera shop, and they said it was not mold, but just some dust. Hard to believe, but this is dust!!!

I can't see any effect on images on performance either ,

I received the lens yesterday from Adorama. The lens body is in perfect shape, especially for a UU date code. The "dust" is hardly that at all. From what I can tell, there are small, minute specs scattered around the 2nd/3rd elements from the front. I am sending it off the Canon today for a clean and check just to be on the safe side. Heck, it is more for peace of mind than anything else. The photos are tack on with my 7d from what I took handheld at 1/640 yesterday playing around. I'll keep everyone updated.

P.S. FWIW, Final purchase price with shipping was $4920.
