I purchased a used 70-200 F2.8 for a great price. 850. It has a small scratch on the perimeter of the external glass. I was fully aware when I purchased it. It's not showing up in my shots but I was wondering if it's possible to have it repaired? Thx. D

If you shoot with a crop camera, it wont even be inside the frame. Shooting with on a FF camera you might see a very small decrease in sharpness in that area, but I doubt you'll be able to see it unless you do some seriously pixel peeping. So I wouldn't spend any money on removing it, unless you want to sell the lens.
I have a Canon 70-200mm f/4 with a scratch like that closer to the center, and I have never noticed anything on my pictures.

I completely agree.
and from the looks of it you have a 50D, so you should be fine.

If It's not showing up in your shots I wouldn't worry about it personally, especially on a crop body.

I think the lens is most likely fine with the scratch. A repair may damage the lens coating and you could be worse off.

It's possible to repair it by replacing the front element, which usually is easy to do and likely the cheapest element to replace because the lens doesn't have to be taken apart. Canon typically would only give you a quote after they have received the lens, though you might be lucky enough to get transferred to a helpful technician. Third party authorized Canon repair facility would have access to the parts catalog and would be able to give you a quote too (for example: http://sp-ts.com/formmail.htm (external link) -- or just call them)

But is it worth doing it? If it were mine, I'd leave it alone.

for the price it will cost you to repair you could have taken your $850 + repair cost and bought a new one or bought one without a scratch used.

Front element scratches rarely impact image quality.

Not worth it, you said yourself it does not show up in pictures.

That is the BEST place possible to have a lens scratch. I have a mark on my 70-200 front element close to the centre. It doesn't not affect image quality. I personally wouldn't bother replacing it. I wouldn't even worry about it AT ALL. It would be such an insignificant scar that I would probably completely forget that it's there.

id talk the seller down to 800 (talk about factoring in the repair costs) and use that baby as is.

But that is just me.

Use a black permanent magic marker (Sharpie, or similar) and fill the scratch with ink. You'll never see it in your photos.

If you leave it as is, you might get see some flare from the scratch in certain lighting conditions, won't see any effect in a most conditions, especially if you use a lens hood.

I wonder what scratched it... maybe a broken "protection" filter?
