Talk sense to me - lenses

[Dale V]

I've had my Canon Dslr just about a year and I've bought a few lenses for it, all genuine Canon and brand new and wanted to keep my dslr a single brand collection. I'm currently eying up a few lenses for the future (not immediate future), but because the ones I'm looking at are a lot more expensive than the others I've previously bought I've took notice of the non Canon brands such as Tamron and Sigma.

The lenses I've got my eye on are:

17-55 2.8 is
24-70 2.8 is
70-200 2.8 is

In non Canon form, you can pick up the lenses brand new for less than half the price of what Canon retail for, but is my thought of "I must buy Canon only" irrational?

I've read reviews and they are favorable, but then there's some saying there are "bad and good quality copies" which kinda seems luck of the draw and out of the buyers hands as to which you'd pick up, where as I assume there would be a stricter quality control on genuine Canon?

Cheers

Thanks for the help.

Raymond, all these lenses would be brand new copies, so from each model would you go for genuine Canon or the sigma/tamron. Basing your decision on quality/price and not depreciation. Are the Canon lenses worth THAT much more?

Yeah steeps, there would be an overlap, I think like you say I'd just buy one or the other. I think I'd lean more towards the 17-55. I'm not in a budget really, but I don't want to be paying more than I have to if they're essentially as good as each other barring the brand name.
