Summary: Love this lens, I do (unprofessional but I like to think of them as professional) landscape photos. I am very new and this lens allows me to seem like I've been taking photos for a long time. Couldn't ask for a better starter lens!!!
Summary: This is a fine wide-angle lens that does not get enough publicity or does not receive the requisite popularity it deserves. You always hear about the 14-24mm, the 24-70mm, and even the 16-35mm as the best choices for ultra-wide to medium-wide angle shots. To be sure, each of them offers advantages and disadvantages that, depending on your needs, may suit you more accordingly.
Excerpt: I was able to find this lens used at a substantial discount. However, it was in excellent shape. This lens is on my camera 50% of the time and my 70-200 VRII the other 50%. You will not be disappointed.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh
Excerpt: This is one of the best wide angle you can get. The reason I settled for this over 14-24 was to ensure all my filters (4x6 & 77mm) to work. When compared to the color and contrast that you can get with 14-24, this one is not as good. But with a little PP you can get it similar results eventually. One limitation is if you are positioning people in the foreground with wider angle (like less than 24 mm), you find significant distortion of the subject (barrel).
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Strong Construction
