The Canon EF 24–70mm lens is a family of professional EF mount wide-to-normal zoom lenses manufactured and sold by Canon. The first of the family, the EF 24–70mm f/2.8L, was introduced in 2002 to replace the well-regarded 28–70mm f/2.8L. Two later versions were announced in 2012. The first of these, the EF 24–70mm f/2.8L II, was Canon EF 24-70mm f/2.8L II USM Lensa Canon EF USM 24-70mm f / 2.8L II didesain untuk meningkatkan kinerja optik untuk lensa zoom standar profesional. Lensa memiliki satu elemen lensa Super UD dan dua elemen lensa UD yang meminimalkan chromatic aberration di pinggiran wide-angle, serta mengurangi color blurring di sekitar tepi subjek.

The EF 28-70mm has better 50% MTF performance at f/2.8 and f/4 than the 24-70mm lens at this focal length. Linear Distortion Linear distortion is slightly more severe in the EF 24-70mm lens than the EF 28-80 as would be expected for a wider range zoom.
It outclasses many alternative lenses to the newest RF 24-70mm f2.8 or 28-70mm f2 and can more than hold it's own even against it's contemporary rivals. It's also one of the fastest autofocusing EF lens of all time. This is courtesy of it's super short focus throw and retro-focus design. 2.

The Tokina 24-70mm f/2.8 is an excellent pro-grade standard zoom lens for Nikon full-frame DSLRs. Tested on the D800E, it delivers marginally better image quality compared to the popular third-party Tamron SP 24-70mm f/2.8 and Nikon’s own 24-70mm f/2.8G, due to its excellent sharpness between f/4 and f/11 at most focal lengths.

The new EF 24-70mm f/2.8L II USM, EF 24mm f/2.8 IS USM and EF 28mm f/2.8 IS USM lenses use a rear focusing system, high-speed CPU, and a powerful ring-type Ultra Sonic Motor (USM) with optimized AF algorithms for faster auto focusing and sharp images. With large apertures these new lenses deliver beautiful, soft backgrounds for superior image

Only one filter may be attached. If you need a polarizing filter, use the Canon Circular Polarizing Filter PL-C B (82 mm).

Try this: 1) In Live View - auto focus as normal. 2) Hit the magnification button, usually to 10X or beyond. 3) Check the focus against a manual adjustment. If you can still sharpen the focus point beyond what the AF has selected there are two options: recalibrate the lens to the body, or alter the AF selection.
