Excerpt: I recently purchased the Canon EF-S 17-55mm 1: 2.8 IS lens to replace my kit 18-55mmk lens, I am so glad I did I have used this lens for macro shots with a extender tube (also purchased fro B&H), landscape and general walk around shots and I love it. The pictures are sharp and crisp with great saturation. I use it on my Canon 70D (purchased also from B&H) with no problems. I would recommend this lens to my friends to replce the old 18-55 kit lens.
Excerpt: I use this lens all the time and love it. The wide is enough for my needs and opening up to f2.8 is awesome. If I had to pick on it for a reason it would be that I wish it could be a longer zoom closer to 105mm.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged
