p.1 #1 · Cost to repair 24-105 scratch?


My 24-105 f/4 has a little scratch in the front element. It may not affect image quality but it severely affects resale value. Any idea how much repair would cost? I don't want to waste my time and money sending the lens to Canon only to learn it's an expensive job.

I'm betting that the cost of repair will be more than the loss in resale value. In particular, if you plan to use the lens for a long time before selling, I'd live with it if it isn't affecting your photographs.

A potential buyer cut $200 off for the scratch. My guess at repair costs was in the ballpark of $200. It would mostly be a spare lens if I kept it; I don't have another 24-105 but I have other lenses I am more likely to use.

p.1 #4 · Cost to repair 24-105 scratch?


I sent my 25-105 f4 away 2 years ago as the aperture blades were sticking and had the front element changed at the same time as it had a scratch.

Parts replaced were Iris unit, Plate, Seal, Optic, Screw according to the list 123 in parts plus 109 labour plus our wonderfull UK Vat.

So I would guess the suggested $200 figure would be pretty accurate.

p.1 #5 · Cost to repair 24-105 scratch?


I remembered reading some time ago that someone had dropped a lens and broke the front glass, I think the cost was quoted at $189, which jives with sparkks. And I think that was before any CPS discount (Gold is 30%, Platinum is 60%).

Tracked down a couple threads:

How substantial is the scratch? The lens is worth around $750 mint. I'd say $625 for a coating scratch, less is there's an actual chip.

It's 3-4 mm long, thin (scratch rather than chip), almost radial at the edge of the front element.

I have no idea where it came from.

You can buy a front element and replace it yourself in about 10 minutes - just peel up the makeup ring, remove 6 screws, replace it with the new one. I believe they are $99 (may have changed I haven't looked at invoices in a while) Part #YG2-2198

But the guy asking for $200 off for a front element hairline scratch is just seeing if he can get a deal. We discount them $75 for a nonvisible (in photos), nonflaring scratch and people can't wait to get them.

What you describe would not even be in the APS-C image circle, 99.9% likely to be invisible in the photos. Knock off 50 off your price, or find another buyer.

p.1 #10 · Cost to repair 24-105 scratch?


Based on my recent experience with Canon CPS, I don't think the repair cost will be cheap. These are the estimates that they sent me:

- Tighten a lens barrel = ~$138 after tax and 30% discount
- Replace top window of 5D Mark III = ~$168 after tax and 30% discount

I don't think these are major repairs with inexpensive parts. I ended up buying the top window directly from Canon, which cost me only $10, and I did the replacement myself.

I have no idea how much it'll cost, but my guess would be something in the neighborhood of $250-$400 based on the above estimates.

Roger...

How does one know when the front lens element is a simple "pop in" and when alignment adjustment by screws or shims is required?

In your experience, does the Canon Parts telephone staffing have the ability to lookup the proper part number based on the lens name?

Thanks...John

Thanks. I had no idea it was a potentially user-replaceable part. I can't find a parts list online to verify current price on a weekend.

Yes, they are able to do that. When I ordered the top window for my 5D3, the representative that I talked to opened up the diagram to check if an adhesive for it needed to be ordered separately or not.

I had thought that this causes lens decentering if a person replaces the front element, since you have lots of experience, are you saying its not a factor?

Thanks

I don't believe the front element is actually a focusing lens, just a protective glass cover, so there is no real alignment to worry about...but I don't mean to speak for Roger and certainly will yield to anyone with first hand knowledge of the 24-105.

As others have said, a virtually non-visible scratch is not likely to have an impact on images. Worst case would be shooting into the sun

- To test this you can cut a small square out of a post-it note, stick it in the middle of the front element, and you won't see it in photos

I think that resale value would only drop by ~$100 at the most, so a $200 repair is not really worth it.

Keep the lens and use it if you can, otherwise resale shouldn't be affected too badly

The 24-105 front element isn't a centering element (although it is an actual lens group, not a protective element). It does have a rotational ability that has a slight near-far movement but if you put the new element in the same position the old one was in (screw marks will identify it) they're almost always (99%) right on the money. I've done several dozen and never had to make an adjustment.

There are several lenses where a front element replacement does require recentering (original 24-70 f/2.8, 70-200 f/2.8s, 100-400) and those are not something I'd try at home. The 24-105, 17-55 f2.8 IS, new 24-70, 70-200 f/4 though, are all straightforward.

I believe Canon charges a minimum of $180 for a repair. So with shipping you're looking at over $200 even before any additional repair costs.

I don't think there is a flat rate. I sent in my 5D2 to replace shutter curtain and shutter box (it had around 280,000 shutter counts). It cost me $416.19 after tax and 30% discount.
