Does it come with the original receipt from a Canon Authorized Dealer dated within the last year? If not it has no warranty that Canon will honor, and the warranty starts on the day of the receipt. Technically they aren't transferable.
"New in box with warranty" really means "used but well taken care of with the warranty card"

The guy that owns it said it was brand new in box never opened and he has a receipt to go with it, I asked him why he was getting rid of it without ever using it, he told me he was an I-T tech and bought it because he got it super cheap his job. Im not sure if this is a BS story or what. But i priced this lens at a local camera shop he had it forsale used for 450, i know they retail for 649, but if it isn't worth a **** at 300mm then it can't be that good. IM not sure what shooting full frame is and why that lens would be better, "Im really new at this" I just figured it would be a kick ass lens because of its zoom, better optics?, and the fact that it is an IS lens.
A few points. The 70-300 is NOT a bad lens. It is quite good for the money out to about 250mm. The 55-250 is quite good, also, at half the money. Both of them are IS lenses. The difference between 250 and 300, as far as reach goes, is not worth paying for.
Full frame refers to the size of the image sensor/film. The 55-250 is an EF-S (not full frame) lens and will not work on full frame/film cameras. The 70-300 will work on any and all Canon EF mount bodies, digital or film. If you don't own a film body, and don't plan on upgrading to FF ($2,000+) any time soon, get the 55-250.
I do use a film body and have no use for the 70-300, on any camera. I use a lesser lens, the 70-210 f/3.5-4.5 (old lens - $100), when I can get away with it, and a 100-400L when I need the reach and/or IQ.
