Our take on the Canon EF 24-70mm f/2.8L II USM Lens

by Woody Sherman

This, quite simply, will be the most reliable and versatile day-in, day-out lens you can put on the front of your Canon DSLR. Why do we say that? Well, first of all, it's in the super-useful "standard" zoom range: 24-70mm for full-frame sensors, and 38.4-112mm on APS-C sensors, so you can get beautiful landscapes and intimate portraits within seconds of each other.

It's also a Canon "L-Series" lens, their premium designation. This means it has superb optics, ultra-quiet mechanical elements, and superior dust and water resistance. And with its maximum aperture of f/2.8, you'll have great light sensitivity to go with the subject-flattering shallow depth-of-field it can generate. If you don't know what photo opportunities await you, this lens is the best place to start your preparations.

Overview: The Canon EF 24-70mm f/2.8L II USM lens is a standard zoom lens for Canon EOS cameras. The inner focus system and ring-type USM (ultrasonic motor) gives you faster, more precise auto focusing. The lens mount has a rubber ring for enhanced dust and water resistance. The 9-blade circular aperture diaphragm provides beautiful soft backgrounds, while the fluorine coating on the front and rear lens elements reduces smears and fingerprints.

Focusing Ring: Regardless of whether you're in manual or auto focus mode, the full-time focusing ring always works. This means you can auto focus on a subject (One-shot AF), but manually change the focus by turning the focusing ring.

Focus Mode Switch: You can switch between Auto Focus and Manual Focus using the two-way AF/MF switch on the barrel of the lens.

Zoom Ring Lock: To keep the lens from inadvertently extending, you can lock the zoom ring to keep the lens at the shortest point.

Lens Hood: The EF 24-70mm lens comes with the EW-88C lens hood, which cuts out unwanted light and protects the front of the lens from rain, snow, and dust. The hood can be inverted and mounted backward on the lens for storage while not in use.

Crutchfield Customer Review (What's this?)
I had the first version of this lens a few years back and sold it because I was never happy with the sharpness of the lens. I got a 16-35 to replace it.

Couple of years later , I decided to buy this lens. It is tack sharp. And quick to focus. No complaints at all! I highly recommend this lens for anyone needing a general purpose lens.

While this is still not my favorite lens because I find it too short or or not wide enough, it's still a lens that I can rely on in times I need something in this range.
Price. But I think the price is fair for a lens of this quality.

Steep but worth it

Written By Igor, Brooklyn, NY on Friday, March 08, 2013
It's quite steep and nearly $1,000 more than the version 1, but I think it's worth it. Having had the opportunity to use this lovely lens for about two months now, I have to say I'm thoroughly satisfied with it. Paired with a 5D Mark III, the AF speed is lightning fast, even in virtual darkness and the lens is sharp, contrast-y, just great overall. Sure, IS would be nice but I really haven't needed it at this focal range. Great walk-around or event lens.

AF is super fast, faster then my 70-200mm f2.8 IS II. It's sharp end to end.
AF is fast, sharp end to end, lighter
