Excerpt: This is my first "L" lens and I am now a believer that the additional cost is worth it. Don't buy into the sales pitches or reviews telling you that other glass "for half the price" is "L" quality - it's not. I bought them and have never been truly impressed.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: I was planning to buy a 70-200 2.8, and by chance I also tried this one. After two seconds I was completely in love with it. It's one of the best Canon lenses and it's also very cheap compared to the 70-200 2.8. However it has nothing to envy to her more famous sister.
Pros: Durable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I shot macros and close-up and own both 5d and 7d. Neither camera could make this lens shine. The quality just wasn't there. Very surprised at canon. Tried the lens for shooting distance shots as well and still not acceptable. Blurry in every case.
Excerpt: I use this lens at the skating rink and other sporting events. It takes a little getting used too because I hand hold it. I found that by bumping up the ISO and the shutter speed it takes crisp pictures. Adding a flash helps.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Excerpt: I shoot with a Canon 6D and own several "L" lenses, so I can say that this is a sharp lens, particularly so at f4+, but I don't hesitate to use it at f2.8; not at all. I use it for informal weddings, street, granddaughter, anything.I read reviews on this site saying that the lens is often soft, and...
Pros: Fast / accurate auto-focus, Lightweight, Nice Bokeh, Sharp
Summary: I love this lens! It's fairly light weight, unobtrusive and fun to work with. As you'd expect with a prime, the image is sharp and the lens focuses very quickly. Because it's so unobtrusive I found it was easy to carry into a concert and none of those sitting near me were disturbed when I took a few...
Summary: I shoot with a 6D, own several L lenses, including the very sharp 24-70 f2.8 Mkii, 70-200 f4 IS and the 135 f2. The 200mm is quite sharp at 2.8, I'd not hesitate to use it here, better at 3.5 and top notch through to f8.
Pros: Very sharp, very quick autofocus, smallish, lightish, great out-of-focus blur
Cons: A little long for really good handholdability
