18-140mm getting scratched up.

I doubt Pete is tossing his camera and lens into a carry-all bag without a lens cap.

You might be on to something and potentially it's the lens cap itself that's doing the scratching? Like Fish, I'm a fan of the Hoya HD2 protectors and have either that or an older Tiffen UV filter on each of my lenses for protection. I've been curious as to whether my lens caps are scratching the filters, but haven't seen evidence of that yet. It could be that the filters are taking the brunt of the lens cap edges and doing a better job of resisting scratches.

Either way, it does sound curious and I hope you're able to figure out what's going on.

Since none of my other lenses have any scratches, this is what I'm thinking. The 18-140 front element sits almost flush so when I put the lens cap on I have to make sure that I'm holding the cap really horizontal other wise it will touch the lens. (If that makes sense. ) All my other lenses are more recessed. Even my Tokina that has somewhat of a bulge sits more recessed. I think I'm just going to buy a filter and use that as a lens cap.

Hmmm That is strange! I know how well you care for your lenses, so this doesn't make much sense!
Have you thought about trying a filter to see if it continues on it's own? Maybe that might stop future damage if it's caused by something touching the lens. Just an idea for ya buddy! :)

That is what I'm going to do. Thanks @Bill16

Well....not to start a debate on it, but yes....I do use a filter on all of my lenses so I've never had that issue. I would use a sensor loupe with magnification to look closely at the scratch mark(s). You might discover something lurking, and then just take the lens on and off a few times the way you normally do, and see if you notice anything in particular that might be a habit that is causing your scratches. Are they long scratches, deep gouges, or just more or less a blemish? When did you first start noticing them? Are they on any of your other lenses?

They are short hairline scratches. You have to turn the lens a certain way to the light to see them. It doesn't effect image quality at all. Like I said in OP I noticed one a while ago then the second one last week and then just a few days ago the 3rd one. No, they are not on any of my other lenses.

Love the phrase cheap glass in front of a lens,you do the maths :D

18 -140 lens cost £580,construction 17 elements so we have £580 divided by 17 = £34 this is allowing nothing for the rest of the lens materials and construction B & W filter on amazon £46

I'd try that before I go putting cheap glass in front of a lens :).

LOL, I would take off when shooting.:hororr: Since I'm suspecting the lens cap to be the culprit, I'll just buy a cheap filer, and put the lens cap over that, and just unscrew the whole thing when I get ready to shoot. If I get more scratches, then I'll know that it's not the cap.

Make sure you read through the lens reviews to see if people can suggest which filter to use. In the back of my mind, I once read how someone tried to put a filter on a lens, but the filter's glass touched the lens' glass. If the bulbous front element sticks out so close to the filter threads, it may pose a problem. I read it several years ago but can't remember the name of the lens.

Could you take a picture of the scratches so we can have a better idea of what they look like?

Truthfully, I don't think my pictures have suffered at all by utilizing filters on the lenses. Some may be hesitant as if the filter will be causing some kind og distortion, but I sure as hell don't see it.

I was just hoping with a wet clean, the lens scratches might just be blemishes that could wash away. Good luck. I hope the issue gets resolved.

BTW, you can get a box of 100 zeiss wipes for $5 at walmart. Blow it off, scrub gently with a wipe or micro fiber cloth and lens solution.

You probably could, but I would buy some lens cleaner....like this : lens cleaner

I would never spray anything directly onto the lens....spray it on to a cloth, then wipe.

I have a whole box of them sitting right here. I use them to clean my reading glasses, but was always afraid of using it on my Cam lenses.
I'll give it a try now.

Ditto on the wet clean ideas (or should I say Plus One). Nikon manuals actually say:

Clean lens surfaces with a blower brush. To remove dirt
and smudges, use a soft, clean cotton cloth or lens tissue
moistened with ethanol (alcohol) or lens cleaner. Wipe in
a circular motion from the center to the outer edge, taking
care not to leave traces or touch other parts of the lens.

I don't know why they spell out ethanol instead of just saying alcohol, unless the idea is to drink it so you don't give a %$#@ about the dirty lens anymore.

Not all ethanol is created equal, so probably better to use a recommended lens cleaning solution or wipes specific to lens cleaning.
