I am thinking of purchasing this Tamron lens (my first non-Canon experience) and I've read a great deal of reviews online and checked out the photos on flickr and it doesn't seem too bad for the price. Granted, it's not a Canon L lens but it doesn't carry the price tag either.

I was wondering if anyone on this site has had experience using this lens and what your opinion of it is? I'm not sure if it would work with my Canon 1.4xextender but I probably wouldn't really need it anyway with this lens. I will be using it with a Canon 7D.

I just received$$$ from paypal for recent photo gear salesand am debating on purchasing this lens or other accessories such as soft box set up, umbrellas, etc.

Any input greatly appreciated,

Denise
