Excerpt: I am a photo enthusiast. This is my first Luxury "L" lens. Ordered it late Saturday night and received it Wednesday before noon in Idaho. Between B&H and UPS they have the whole delivery process down pat. Great Job! The lens, after the first two hours of use, is everything everyone previously raved about. I have the 70-300mm f4-5.6 is usm (non-L) lens and it is really good, but the first test shots with the 70-200mm f4 is usm made me say WOW!
Pros: Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
Excerpt: Just got the Canon 70-200L f4 IS lens. This is my first L series lens. Early pictures taken with a Canon 7D are outstanding. Our recently adopted puppy was the subject; got numerous compliments on the clarity of the photos. Every wisker and hair around the face can be seen.<br /><br />The lens is expensive, but the picture clarity is outstanding. Quality has its cost. Build quality is excellent. Although somewhat heavier than other lenses owned, the balance is good.
Pros: Fast / accurate auto-focus, Strong Construction
Excerpt: This lens is sharp from wide open and performs beutifully. Bokah is creamy and from reviews is better than the 2.8. A must have lens if you can't afford the 70-200 2.8 or do not need the extra stop.
Pros: Consistent Output, Durable, Nice Bokeh, Rugged, Strong Construction
Excerpt: This baby paired with my 5dm3 are stunning. The autofocus is razor sharp and lightning fast. Its about half the weight of the famed f2.8 L, which is why i purchased this lens over the 2.8. So save the money, and get this lens! You'll be glad you did!!!!!
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Strong Construction
Excerpt: The Canon L series lenses have excellent sharpness and clarity. Check out the quality on the lens group on Flickr. I use it for outdoor photography and I am able to crop the image from my T2i and still get excellent sharpness.
