Summary: I'm a professional photographer and using this lens to give me some extra power for outdoor game photography. I often shoot from a standard sized football/soccer field from the end zone and can capture clear full-body sized action images when the players are in motion and from about 50 yards can...
Summary: Let's get this out of the way at the beginning. This lens is huge, heavy, and VERY expensive. The price is very hard to stomach, but when you take a while to realize the technical brilliance and attention to perfection that went into designing and manufacturing this lens, it becomes apparent that...
Summary: This lens is about cramming in as much light as possible without sacrificing (serious) loss of quality when fully open. It is just wonderful for wildlife or some sports photography in low lighting.
Simply amazing lens. Sharp, great colours, fast, well built.

Summary: This is my upgrade lens. I used the 100-400L IS lens for birding before this lens. I use this lens on 7D with or without TC's. Pros: - Well built - Weather sealed - Sharp wide open - Bokeh is amazing - Mind blowing colours - Very good resolution - Very fast on 7D - Almost noiseless focus.
Summary: Very sharp, and with intangibly better feel of the images compared to the cheap telephoto lenses. This copy has a dead-on focus, which is expected here, but rarely happens with the cheap ones. Pleasant bokeh.
Summary: If you have the $$, buy the 300mm f2.8 now. If your a birder and a have a strong arm, you might consider 500mm f4. The 300mm f2.8 is a must own lens, and yes this lens is a 6. Some of my pics here: [...]
Summary: I've had mine for a couple years now, then added 1.4, and gets mounted on the 1DsMkII when at the race track usually. Quite the beast when this set-up has to be toted around. A quick 60 second sample at Youtube of Iowa Speedway will show you how far from Tv camera operator up on crane about 250 feet...
Summary: This is a beast of a lens that can create some incredibly sharp images. Bolted to my Canon 7D (an APS sized sensor) this works out to be a 480mm f2.8 (35mm equivalent) lens. I have never seen images this sharp in my life. My primary use for this lens was football, night games.
Summary: I had been looking at this lens for a long time. I was skeptical of the stellar reviews and extremely hesitant to drop the $[...]. I wanted to see for myself first so I rented a copy from [...] (BTW, great company). For seven days I shot everything imaginable with this lens.
