Excerpt: I've used this lens for portraits & sporting events. I am extremely pleased with it's performance at sporting events, it's quick & sharp. It out performs my 70-200mm 2.8 L USM II in the clarity of the photos. I've shot many photos using the 135, in low light there are problems. However, I do notice a couple things with the 70-200 that are lacking, but there are strengths as well.
Excerpt: I use this for weddings, instead of the 70-200 2.8. This lens is lighter, smaller, and faster. If you want to differentiate yourself just a bit, use this lens. The separation is stunning, the bokeh creamy.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Excerpt: I bought this for the wide aperture to give me a little better isolation of subjects. Things look great so far. I'm looking forward to working with it and to force myself to do more portraits. It is sharp and colors look really good.
Pros: Durable, Fast / accurate auto-focus, Nice Bokeh, Rugged
Conclusion: Of course it is fine quality, fast focusing, and tack sharp. I knew all that before I bought it. What has continually stood out to me about my 135 is how BEAUTIFUL my photos turn out; so very pleasing to the eye. For my needs (and low light photography is one of the things I really enjoy) IS would not be a meaningful addition to this lens. This lens is a bargain. It is also a specialist.
Conclusion: I had read for years that this was perhaps Canon's sharpest prime. After shooting with it for several months now, I have to agree. The focal length is a little bit of an adjustment when shooting casually on a hike or in the street, especially if you are used to a 50mm or zoom, but once you get comfortable, this lens will hardly leave your camera. With a still subject, such as an arranged portrait, this lens shines.
Excerpt: Best Canon L lens! <br />Perfect for Portrait and Street Photography as well.<br />Pairing with my Canon 16-35L f/2.8 II, 24-70L f/2.8 II, and 35L f/1.4 perfectly. <br />If I would pick one and one lens only! This Canon 135L f/2 is the one!
Pros: 6d 16-35l 24-70l 35l, Best L Picked, Consistent Output, Lightweight, Nice Bokeh, Strong Construction
