scratched new lens

So, I just got my 70-200 f4 L a couple a days ago. Used a blower brush ting now to clean of some dust. Blew on it, then gently brushed away some that didn't blow off. And guess what? The brush made a ~inch long scratch on the front element, not cool!

I brushed a blank CD now with the brush and easily made scratches in it. Is this normal? I thought I was very gentle.. Bought the brush from Penn camera around here. I'm not going to use the ting again at least.

Anyone how would this work with warranty or B&H return policy? I suspect not very well..

Maybe this will serve as a warning to someone else at least..
Thanks

Yeah I guess it won't make much difference to IQ but even so it's not something I'm particularly happy about.

ps: yeah I know a UV filter would have prevented this but I only use them if I have to.

if you scratched the lens you'd have to lie to get canon or BH to take the hit for your mistake.

Is this a lens brush? It's actually not all that easy to scratch these lenses much less with a lens brush. Are you sure it isn't just a smear? In come cases a brush that touches oily substances can leave marks across a lens. Use a lens cloth and gently go across this scratch and see what happens.

how would a lens brush cause a scratch? even with debris on the brush I'm have a hard time imagining that a brush could cause the scratch. You sure just didn't notice the scratch after you brushed it.

How long have you had the lens? was it scratched when you got i?

No way a "lens brush" scratched your lens. Wire brush...maybe. The optical coating on the lenses today is pretty darn good stuff...you have to work to scratch a lens.

yupp it's a lens brush, bought at penn camera for $5 or so I believe.. Like I said I can scratch a CD with pretty gently brushing..
Pretty sure it wasn't there before either, looked at it closely earlier.
Took a picture of my wall but couldn't see it when zooming it on the pc though. Guess I'll just have to live with that. thanks for the replys

lenses do not scratch easily, today I witnessed a guy with a filter on a wider lens drop the whole body onto a wood gym floor and the filter shatters, the fragments glass of got wedged between the remains of the filter and lens. he removes the filter and the lens has no scratches at all, he was so lucky and I was amazed.

I would bet a first-class steak dinner that you have NOT scratched the lens or the CD. You have, most likely, laid down a strip of some contaminant from the brush. As others have said, it's rather difficult to scratch a lens or even a CD with a brush.

Take the lens, CD, and the brush back to where you bought the brush and insist that they help you clean the lens and the CD and refund the money you spent for the brush.

It is probably just a mark on the coating, lens is not easily scratch. Try use a lens pen to clean it.

Use sandpaper to even it out then move to fine sandpaper to smooth it even......... :)

I agree that it's likely not a scratch. Get a lenspen and breath on the lens, then rub it out...probably just a stubborn mark.

If the brush IS causing the problems, contact Penn camera and tell them you'd like them to pay for the lens repair.

Or clearcoat automotive polish. If that is good enough for sportscar fanatics, it has to be okay for the lens. ;)
