Summary: I actually sold my L-series 24-70mm Canon lens to buy this one. While the L-series lens was great it cost $1,200 and was super heavy. It was so heavy that it made my Canon 70D weigh 6-1/2 lbs with it on. I find that this lens takes photos that are just as good and it doesn't weigh much when it is on my camera. I am super happy that I made the switch. This is now my everyday lens.
Excerpt: I love this lens, it's so much better than the lens that came with my Canon. It shoots better close up photos, and has more zoom capabilities. That's what makes it so great as a regular go to lens.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Great all around use
Excerpt: This replaced a wide tele that I dropped in Alaska. Got this shipped and had it within 3 days. I have a T3 for most of my 'everyday' shots and it has stayed on since it arrived. Color is far superior to the 18-55. Sharpness is better. Using the Canon RAW software I've gotten photos much better (sharper - accurate color - very little noise) than with the 18-55 kit lens. Quiet with video. I put on a good glass UV at first but it's gone. Shots were excellent without it.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: The first zoom of any brand that I've found to give sharp, consistent results throughout the entire range of focal lengths. A true value for those who cannot afford the L series glass. I'd recommend it to anyone.
Summary: I love this lens. It is silent while focusing for movies with the new STM engine. It takes great sharp pictures. This is the primary lens for our SL1. It is a good balance. I recommend this for the casual shooter that wants to get up close and personal and yet still wants enough lens to reach out there when necessary.
Summary: We are using this lens (we have two of them) on a Canon 70D and 7D Mk II. We have a Sigma 18 to 250 mm 1:3.5-6.3 DC Macro OS HSM lens with which we were becoming increasingly unimpressed as a general walk around lens. The images seemed flat and lifeless somehow. This Canon lens is much much better. The images seem to jump out at you. This may be because the Canon camera body recognizes the lens and applies corrections to the image as a result.
