Basically ,there are 1st class lenses in all makes,in sigma the better lenses have EX elements in them and are superb.
They are dearer ,but if you want quality you have to pay for it.
In the Nikon range they call it ED glass and it to is superb,but very dear also.
I have spent a lot of cash buying lenses willy nilly.
My advice through experience is to wait till you know what lens you want,tele,macro,wide, and then save to buy the best glass you can,
Cameras loose value over time,but good glass is always wanted so never does.
