Default Speck of dirt inside of new lens.

I just received a new lens ... a Canon 50mm 1.8 II ... and it has a small speck of white "dirt" stuck somewhere inside of the lens ... its easy to see. I took some shots and it does not seem to affect the images but they were not taken under "controlled" conditions .... its on the outer perimeter about 1/4 inch from the edge and its not "floating" and almost certainly is not a "bubble".

Is there a more "scientific" way to test to see if this spot will cause image problems? Any suggestions pertaining to this problem are most welcome. I would rather not send it back unless i have to ... it is wise to live with such an issue even if the images seem to be clear?

Thanks one and all in advance.

A speck of dirt inside the lens will never be in focus, and so will never appear in your photos. At most, it will block some light, and, since it's white, on extremely rare ocassions, it may cause flare.

But I'd take it back.

Thanks for the advice TCav. I do suppose sending it back is the correct thing to do ... but I have to mail it to Canon Canada ... and it will take weeks to get it back ... grrrrrrrrrrrrrrrrrrrr

little devil on one shoulder says ------------> look what Tcav said ... it wont do any harm

little angel on other shoulder says ---------------> don't listen to that devil and do what Tcav says.

If you just received it, why can't you send it back to the retailer for a replacement?
