Excerpt: This lens is fantastic, and will help a skilled portrait photographer produce excellent images. Compared to my other L series portrait lenses (which are also amazing) this lens is superior in many ways. For instance, it seems even sharper and quicker to focus than my 135mm f/2 L. Previously, I had thought that the 135L represented the "ceiling" or the absolute best performance/image quality that can be had.
Pros: Consistent Output, Fast / accurate auto-focus, Sexy As F, Twice As Fast As F28
Cons: Attention Grabbing, Expensive, Heavy, Not An Indoor Lens Duh
Excerpt: Sharp, Sharp, Sharp. So sharp you won't have to post-sharpen your image, especially a portrait subject.I received my lens last week and photographed my 4 year niece a few days later at the park with lens attached to a Canon 5D Mark II. Photographed her in open shade at 1/125 sec @f/2.8, handheld with IS turned on. I can't believe how sharp the image is at f/2.8 and the sharpness and creamy bokeh can't be beat by the Canon 135mm and 70-200mm f/2.8 II IS lens set to f/2.8.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Incredible sharpness, Nice Bokeh, Rugged, Strong Construction
Excerpt: My previous 200mm f2 was the Nikon version vri. Im happy with the Canon version as its technically 400 grams lighter which is a lot when you have to lug it around all day. Performance is around the same. Feet on the canon is better. Collar on the canon is better with preset 90 degree positions that click into place. Make sure you get the don zeck cap with this. I was lucky with my copy as i did not experience the noise issues when paired with the 5d mark iii.
Summary: In this lens you can basically buy youself into the ranks of the great candid portrait photographers, when combining this with the 5D3, you can automatically take terrific photos of young people, but the old folks may not like the photos because they are too revealing. Try to politely change a lens or intentionally blur the images when you are shooting moms and grannies.
Conclusion: One of the greatest lens I've ever used. I had the f/1,8 FD version, which was already stunning, but this new model is even better, especially wide open. And the stabilizer is a great addition. To improve this lens, I can only think about a shorter minimum focusing distance. Other than that, this lens is just perfect from every point of view, regardless of the diaphragm, the lighting or the distance of focus. Bokeh is very beautiful.
Pros: Fast auto-focus, Superior build quality, Super-sharp images, bokeh, sharpness wide open, color rendition
Summary: Excellent lens for indoor (i.e. crappy light) sports. Very sharp pictures, and has stood up to a beating. I dropped it and cracked the lens hood. The only reason I'm not giving it five stars is pricing issues. A new lens hood is $500, which seems a bit steep, as does the price of the lens. Performance wise, no complaints.
Excerpt: Fast glass - yes, super shallow depth of field, an extra stop of light vs a f/2.8 lens. Claimed to be the fastest 200mm in production. Fast focus - yes but not as fast as the 70-200 f/2.8 II, or the 300 f/2.8 II. Of course the 220 f/2.0 is MUCH faster to focus than the 85 f/1.2 II. Buy the lens cap designed for the 300 f/2.8 II as it works much better than the silly leather boot that comes with the 200 f/2.0. Recommended.
