Good news! (kind of...)

    I shot a macro of what I thought was a chip in my lens. Turns out, it's steel melted onto the glass. Anyone have any ideas of how to remove it with the least chance of damaging the glass further?

    Update: I ended up just leaving it on there. No effect on image quality.

      And if you're asking yourself how in the world does someone get melted steel on their lens...

      Given that the metal is opaque I would think it more likely to distort if you get it off and the glass is warped underneath. Right now all you have for distortion is some relatively small diffraction effects and a shadow that is very spread out in the image and doesn't appear to be noticeable, So leaving it on may be best. However if it just melted a coating on the lens you may be able to pick it off with your fingernail or something. I wouldn't go as far as using something metal to scrape it off though - that'd be just begging for trouble. If you get it off you could get a distorted bright spot somewhere in the image if the lens itself is warped. .However if you get it off and it does distort, you can probably get it back to the way it is with a small dot of black paint.

      I was thinking same thing is try your fingernail to scrape or pop off. Maybe a hot sauder tip just above the metal too warm up then wipe off? Let us know any luck of removal. Good Luck!

      PS I had been looking into doing some steel wool spark photography . . . until my recent sparks at the house lol and now knowing hot flying metal may stick to me or the lens I think I may skip trying steel wool spark photography. Think next I want to learn how to take and stack photos.

      It seems very likely the lens coating will come off with the metal blob, but that's probably better than leaving it on there. On the plus side, hooray for Nikon's quality lens coatings! They hold blobs of steel!

      It would be easy to make a big scratch prying it off. What if you got the lens really cold? Would the difference in material expansion just let the metal fall off? Another approach might be to press a piece of very sticky tape over it, and hope the blob comes away with the tape as you slowly peel it off.

      From seeing how solder blobs stick to stuff, I think maybe it is only held at a few small points underneath. It might not be stuck very solidly. Do you have a massively powerful magnet you could hold near it?

      I thought about the cold idea last night (good weather for it.) My main concern is that since there's no noticeable effect, removing the metal might be worse than just leaving it on there. Although as mentioned above, I can always dab some black paint on if the metal comes off and the damaged coating causes weird issues.

      Magnet would be scary near all the electronics and little moving parts in there. ;)

      Outer lens damage is not uncommon (ie finger prints). I would just take it to Nikon and get a quote to replace that piece of glass.

      Why didn't he have a UV filter on if he was spinning around a blob of molten metal???

      The 14-24mm does not accept filters.
