EF 24-70mm f/2.8L II USM
24310

Overview
Meeting the ever-increasing demands on image quality that digital photography brings, the redesigned EF 24-70mm f/2.8L II USM is the latest update to the acclaimed L-Series of EF optics, re-establishing a new standard for superb optics, high-end durable construction and performance in professional zoom lenses. A standard focal length zoom lens, it features a large aperture throughout its focal length. Featuring the latest advances in optical lens design, it utilizes 1 Super UD lens element and 2 UD lens elements that help minimize chromatic aberration in the periphery at wide-angle as well as reduced color blurring around the edges of the subject. In addition, 2 types of aspherical lenses are combined to help reduce spherical aberration over the entire image area as well as through the full zoom range. Optimized lens coatings also help ensure exceptional color balance while minimizing ghosting. The lens is also equipped with a circular 9-blade diaphragm for beautiful, soft backgrounds. A ring-type USM and high-speed CPU with optimized AF algorithms enable silent and fast autofocusing. Built for the rigors of professional use as well as to meet the increased number of shots available with digital photography, it's constructed with improved dust sealing and water resistance while fluorine coatings on the front and rear lens surfaces help reduce soiling, smears and fingerprints. A zoom lock lever locks the zoom position at the wide end for safe transporting while attached to an EOS DSLR camera over the shoulder.

Several prime lenses in one
Photography has been my hobby for over 20 years. I am not a pro. In order to evaluate a new lens, I shoot everyday life instead of brick walls. This lens is sharp wide open at F2.8. You do not need to stop it down to increase sharpness. This is what I love about this lens. It is like having several prime lenses in one package. I used the 35L and 50mm F1.4 for several years. They are good lenses. But I had to stop them down from F1.4 to F2.0 or F2.8 to get sharp images. The combination of this lens on a 5D3 are heavy. Carrying them around for a full day is not easy. Despite the weight, I still wish it had image stabilization. Its autofocusing is very good, although it is not any better than the autofocusing of the 35L or 135L or 300mm F4L. But then again, I haven't done any scientific measurements. This is all based on my everyday use. The bokeh is "good". Although I much prefer the bokeh of the 135L. Shooting into bright lights is surprisingly good. Overall, I love this lens. I don't like the high price though. But if you think of it as several high quality prime lenses in one, I guess that can justify the price.

A definitive contender...
If your still doing homework on a lens of this caliber and price tag, then my review should only add confidence in a purchase. The build is of rigid and pretty standard professional grade expectations added the weather seal for environmental elements. I shouldn't be noted but common sense applies to complete the seal with a filter as stated in the manual. Im old fashioned and like the heft and feel, i could ask for better containment than engineered plastic, how about t-6061 aluminum?? Maybe then no one would complain about a price-tag. Furthermore, the optics are just phenomenal, from 24-70 if you use the focal length respectfully. Sharp, sharp, sharp and not afraid to use it wide open in any circumstance. Slightest distortion but critical in studio. Focus and zoom execute excellent and comfortable turns. simply a pleasure and all around contender.

EF 24-70mm f/2.8 II USM
I received this lens on Monday, and sold my previous favorite, the 24-70mm L f/2.8 on Tuesday. I have waited for this lens for too long. I shot all day Monday and found this new upgrade really brilliant; It's lighter, looks better and the photos that come out of it are a lot sharper. The color rendition matches those of my 85mm L f/1.2 and the 70-200mm L f/2.8. If Canon had included IS into this baby it would have been a work of art, a masterpiece. I am sure there is a reason for this; Canon knows better. I shoot manual and don't think I desperately need IS. Moreover, I am learning how to lock my elbows as I shoot, and the result is paying off...I have taken about a thousand photos and every single of them is as sharp as the other.
Thank you Canon. I love what this lens does!
