Wide angle & macro lens

I HAVE CANON EOS REBEL T2I ( LENS EFS 18-55-MM).
I LIKE LANDSCAPE PHOTOGRAPHY. I LIKE TO BUY WIDE ANGLE & MACRO LENS.PLEASE ADVICE ME ABOUT BEST LENS . THANK YOU

In the Canon range, where I suspect you will not go wrong, there is the EF-S 60mm f2.8 Macro USM. This could well be the lens of choice, although Tamron, Tokina and Sigma will offer lower cost options.

As for wide angles, the EF-S 10-22mm USM looks good. Perhaps the Sigma 10-20mm, or the Tamron 10-24mm could be alternatives. Tokina also has the 10-17mm Fish-eye zoom, an interesting ultra-wide with a different look.

Of course, there is no "best lens" per se, but if you start by looking into the ones I've mentioned hopefully you will narrow it down to the ones that suit your own style of photography.

Best regards

John
