Hi.. I am talented to take good shots and I like photographing so much but I didn't study and I miss some basics to be a professional but I shall learn soon. My Canon Cam EOS 500D with a standard. Lens 18-55 mm. Which lens you advice for better zoom & angle to take shots in open areas and mountains and help me in my architectural career.. Thank you in advance
Sounds like you want to venture into wide angle lenses.
The Canon 10-22 is a great wide angle lens for crop bodies like yours. You have some other options as well such as the Tokina 11-16 but it has more limited range and is basically a "pseudo-prime" lens (but at 2.8 it is fast) and affordable.
