Need a bit of help porfavor!

[alejandraw.]

I currently have a Canon 20D ( am looking to updgrade ) that comes with the 18 55mm and also purchased a 50mm 1.4.. canon speedlight 430, I do mostly portraits but have been asked to do wedding photography recently, what lenses would you recommend for that as well as portrait photography, any must haves? and also, any recommendations on sigma or tamron, canon lenses are just so expensive for me right now! Thank you so much for the advice in advance

You need coverage to go from very wide to medium-long telephoto. I would look at the Sigma 10-20 f3.5, and 24-70 f2.8, and 70-200 f2.8 in whichever ,maker you like the feel/look of better.
