Tammy 70-300 LD or Canon 75-300 III?

Getting one or the other for my mother who is a newbie on a Rebel T3 and barely has any idea what she is doing.

All my stuff is top-tier L lenses I know nothing about these but she won some money at slots I guess so she wants something with some reach.

They have good reviews, if not a bit over technical and harsh when rating lens that are not top tier.

The 75=300 is pretty bad and I can't speak for the Tammy. 55-250 would be my choice.

+1 on the 55-250IS. Stay away from the 75-300.. even if it's free.

Yes if you can swing it pick her up a 55-250mm is

55-250.

I got a 75-300 MkIII with my first dslr and I only kept it for just over 2 months and for most of that time I was trying to sell it. Mine wasn't the USM version and IMO I think it's probably Canon's worst ever lens. It's the only lens I've ever owned that I've got no photos taken with it. Not 1 keeper in about 9-10 weeks of having it. I'd have to agree with the others above and go for the 55-250 IS, which is a cracker of a lens.

Amazon has the 55-250 for $189 today w/ free shipping and, depending on state, no tax. While not a super deal, still a decent price for a very respectable budget zoom lens.
